Abstract
Macro-level evolution as a function of time can be applied to four descriptors to plot
the maturity of a technology and thereby indicate the primary course for maintaining
technological supremacy. This pattern of design evolution is based on a primary discovery
of Altshuller: the evolution of a product or technology parallels the micro-evolution of
biological systems (the biological s-curve). Researching data relevant to critical
performance criteria of a technology, the number of inventions in this technological
field, the levels of the aforementioned inventions, and the profitability of the primary
resultant of the technology in question will allow interpolation and correlation of data
that will indicate the resultant location on the s-curve1. The derived location on the curve (pregnancy, birth, childhood, maturity,
or decline) will indicate to the manager of technology what posture should be assumed:
further investment in the current technology, stasis, or various levels of research and
development for a technology that will replace the current technology (pre-decline,
maintaining a positive profitability). A careful study will yield valuable information
based on data and the statistical analysis of this data in light of the Theory of Directed
Evolution. This unique ability of the theory of innovative problem-solving demonstrates
its versatility and power with respect to design and development.
A reduction to practice of this theory will be demonstrated by a case
study about the direction of self-heating (exothermic chemical reaction) container
technology.
- Introduction
Evolution in stages is a macrolevel methodology aimed at the
maturity mapping of an existing technology. The stages of the S-curve are pregnancy,
birth, childhood, adolescence, maturity, and decline. Four curves plot the maturity of a
technology from different perspectives: performance, number of inventions, the inventive
levels of those inventions, and profitability, see Figure 1.0. The interpolation of these
individual curves gives the analyst an indication of the technologys location on the
S-curve. Understanding this mapped maturity allows strategic decisions to be made
concerning the investment of resources related to research, development, marketing, and
sales. Understanding maturity allows the corporation to maximize the utilization of
limited resources as well as market profitability. It is for at least these two key
reasons that maturity mapping addresses fundamental issues associated with corporate
survival during the coming millennium.

Figure 1.0: These four curves plotted versus time indicate location of a technology in
reference to the extrapolated polynomial fits of previously studied technologies2. The data in question may be sufficient only
to re-create a portion of the experimental curves indicated above. Correlation of the
existing data may be accomplished by aligning the data regression with the appropriate
portion of the indicated descriptors.
- Summary
Self-heating container technology has had patent activity from starting
from 1976. The patent activity during the ensuing 23 years has been varied and
non-consistent. These particularities make self-heating technology an ideal candidate for
maturity mapping. Data were collected relevant to the technology that would provide
necessary information to create the required graphs represented in figure 1.0. The search
criteria was devised using Boolean operators selected to insure capture of relevant and
associated self-heating technologies. The abstracts were then reviewed for relevancy and
the database was modified accordingly. A properly constructed search can reduce the
abstract review period while a search criterion that is too broad in nature will
significantly increase the abstract review period.
Performance
Sustained core temperature was selected as the primary performance
characteristic to trend. Data concerning sustained core temperature was collected from
literature and company specifications for the last twenty years. This data was plotted as
Figure 2.0. The core temperature sustainement is measured in seconds beginning when the
specified core temperature is reached and ends when the specified temperature is no longer
maintained due to exothermic exhaustion (the nominal required temperature is monitored and
considered attained to +/- 5 ° F). A portion of the energy created is required to
thermally condition internal membranes and is therefore not directly translated to the
temperature elevation of the beverage. Due to this, beverage temperature was also selected
as a primary performance characteristic. Beverage temperature would be the final quality
criteria performance would be based on as it is directly transferred to the customer.

Figure 3.0: A second performance criterion was plotted for beverage temperature. There are
noticeable differentiations in core temperature and beverage temperature.
Number of Inventions
The number of self-heating technology patents was collected from a
patent database and these figures were collected and plotted, see Figure 4.0.

Figure 4.0 Patents per year for self-heating technology (and relevant criteria not
specifically naming "self-heating"). A chart produced by Invention Machine TOPE
3.0 is reproduced below indicating almost identical information (demonstrating accuracy of
the IMC search engine(s))

Level of Inventions
The associated aggregate level of inventiveness for the patents
disclosed in Figure 4.0 are plotted below as Figure 5.0. The criteria used for level
determination was primarily a combination of the following categories and the individual
patent ranking versus each. The category list used was as follows:
Required trial and error iterations (if known or surmised (acknowledge
strength or weakness of any assumption(s))
Presence or absence or invisibility of a contradiction(s)
(administrative, technical, or physical)
Number of contradictions
Strength of the contradiction(s)
Impact on the relevant field
Impact on science
Degree of system change

Figure 5.0: The highest level of the inventiveness is represented per annum as an
indication of the overall state-of-the-art in self-heating technology during the time
frames indicated.
Profitability
Profitability and bookings were investigated and plotted in the
following Figures 6.0 and 7.0. There are many indicators that are evident without
utilizing profitability data, as the company in question is a relatively young company. It
is primarily in the "start-up" phase with reference to the evolution of the
organization3.:

Figure 6.0: Profitability is plotted with reference to time and indicates losses
for the first twenty. The peak in profitability is the result of the emergence (birth) of
the technology.
- conclusions
The stage indicators placed the existing self-heating technology in the
infancy stage. This is demonstrated by superimposing the predicted curves from Figure 1.0
over the experimental data from section 2.0. In each case the correlation suggests an
immature status. A clear strategic implication was realized: invest in the production and
marketing for this technology. Previous technologies were employed but the peak core and
beverage temperatures realized were inadequate due to secondary limitations (or problems)
associated with the technology in question (e.g., cost to manufacture, weight, safety).
Therefore, there were several s-curves that were initiated but each declined prior to the
emergence of the technology. This is the first cycle of this technology that has emerged.
Several secondary problems were resolved and innovative design and utility patents were
filed that will protect this technology as it matures. Maturity mapping will be utilized
to insure the growth of this technology is understood and strategically managed to
maximize profitability. Resources will be directed to a superceding technology at a point
conducive to the maintenance of a positively sloped profitability curve.
