Application of TRIZ to Stapling the Contradiction Matrix.

Introduction
When I was introduced to TRIZ, I tried to test it by applying it everywhere, irrespective of any of the technical field. The reason to do this was not only skepticism but curiosity– can we innovate or improve things in such a simple way?
Whenever I went to buy anything I looked at the opportunities to apply TRIZ to develop the product to next level. I tried to figure out how a product had evolved to its shape, size and features and looked at the competitive edge of one product over the other. To my amazement I was able to find TRIZ principles everywhere in technical and non-technical fields. At the same time, I applied TRIZ to my stapling of the contradiction matrix.
The problem
When a document consists of many pages the simplest way to keep them together is to staple the pages. Stapling makes the document a sequential arrangement of pages - easier to hold, store, file, and read.
There are various methods for stapling. The figures below show the method to staple which is termed as “back-to-back” stapling.
Figure 1
Figure 2
In the first two figures the pages are stapled at angles 0 degrees and 22.5 degrees respectively, with respect to the Y-axis. Another variant of the “back-to-back” stapling can be 45 degrees, 67.5 degrees and 90 degrees as shown in the next few figures.

Figure 5
The variants in Figures 3-5 show that the angle of stapling can be changed for easier navigation between pages.
The same “back-to-back” stapling method was used to staple the pages of the contradiction matrix. There were two pages of the contradiction matrix and only the first page had the row listing ‘worsening features.’ The following figure shows the available contradiction matrix. My problem started when I tried to staple two pages of contradiction matrix back-to-back.
Figure 6: Contradiction Matrix (page 1)
Figure 6: Contradiction Matrix (page 2)
In back-to-back stapling, navigation was not simple because in order to check the ‘worsening parameters’ I needed to either count columns from the left or check from the first page, which was not only tedious, time consuming and difficult, but also error prone. Thus, I had a problem, a contradiction and a potential to apply and discover the power of TRIZ at the time of learning itself. The following figure shows how the pages were stapled back-to-back.
Figure 7
Figure 8: Other Possible Variant of Stapling
Figures 7 and 8 show variants of the stapling method. In a more sophisticated way the pages can be stapled back-to-back on the X axis as shown in Figure 8, rather than stapling on the Y axis. But in these scenarios the contradiction was that stapling the pages made for better handling and reading, worsened my navigation-ability and my ability to read correct column of ‘worsening feature’.
If I tried to improve parameter 33 - ‘ease of operation’ (by stapling) other key parameter 28, ‘measurement accuracy’ worsens. Using the contradiction matrix I identified the following principles as applicable for improving the contradicting parameters:
Improving feature: ease of operation 33rd parameter of contradicting parameters
Worsening feature: measurement accuracy 28th parameter of contradicting parameters
On mapping the same on the TRIZ contradiction matrix, the following principles are recommended:
33 @ 28 = 25, 13, 2, 34
“@” represents “at the cost of” and should be read as 33 improves “at the cost of” 28.
Principle(s) to apply are:
Principle 25 - ‘Self-service.’
Principle 13. - 'The other way round'
Principle 2. - ‘Taking out’
Principle 34. - ‘Discarding and recovering’
Solution One
I began with Principle 13 - the other way round - I interpreted as changing the direction/place/dimension of stapling. In this case, rather than stapling pages one behind the other (e.g., back-to-back) I put them together, one below the other and stapled them making navigation simple. This is illustrated in Figure 9 below.
Figure 9
Still, due to the gap on the pages navigation is not that very easy.
Solution Two
Next I tried using Principle 13 in conjunction with Principle 2 - ‘taking out’ - applying the principles together for a better solution.
Rather than stapling pages back-to-back or one below the other I turned them inside; (a variant of ‘other way round’) that is both blank sides facing out with the matrix inside. [If you plan to try this yourself, check that bottom row of first page (number 19 in my case) of table is touching top row of the second page (number 20 in my case).] Now, staple the pages from outside such that the extra space between table contents is out of the staple pins. Flip the page, fold the pages along the staple pins and the table is in order without any navigation issue. The pages are stapled inside-out and the white space of the paper is out by folding the stapled area of page. (See Figure 10.)

Page 2: The second part of the matrix
Figure 11: The Solution
Taking into account Principle 13 in conjunction with Principle 2 I stapled the contradiction matrix pages such that the matrix looks like a single document even though it’s a two page document. The stapled matrix has improved accuracy and ease of navigation, documenting, filing and handling. Additionally, the folding and documenting, filing of the contradiction matrix is easier when compared to variant Figure 9 of the solution.
Conclusion
TRIZ, even though devised using the patent database; can be applied in relatively simple areas like stapling pages, proving that it can not only be applied in technical fields but in non-technical fields too. TRIZ is a versatile and universal tool for innovative thinking, tackling psychological inertia and solving contradictions.
