Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the area ratio for the three primary colors is set to 1:1:1, then the design is simple, but the light current ratio becomes non-identical (18:23:16) leading to complicated power amplification circuit design
Solution Approach 1:
The patent changes the light reception area ratio parameter from the conventional 1:1:1 to a specifically designed ratio (e.g., 29.8:16.1:10.1) that compensates for the optic sensor's wavelength-dependent response characteristics. This parameter change directly adjusts the light current output ratio to be identical, thereby simplifying the power amplification circuit design and eliminating the need for complex compensation circuits.
2Ease of manufacture
If the area ratio is 1:1:1, then the design is simple, but more integrated circuit chips are required leading to increased costs
Solution Approach 1:
By changing the light reception area ratio to a specifically designed value, the patent achieves identical light current outputs directly at the sensor level. This eliminates the need for additional integrated circuit chips for signal balancing, thereby reducing the total number of chips required and lowering overall system costs.
3Ease of manufacture
If equal area ratio (1:1:1) is used, then manufacturing is simple, but the light current outputs are non-identical requiring complex circuit design
Solution Approach 1:
The patent determines a specific light reception area ratio based on the optic sensor's response spectrum characteristics and uses this precise ratio to achieve identical light current outputs. This approach maintains manufacturing simplicity while achieving precise light current ratio control, as the area ratio can be directly controlled during the sensor fabrication process.

AI summary
A method for adjusting output ratio of an optic sensor includes the following steps: measuring and obtaining a response spectrum of the optic sensor; analyzing optic response ratios of the response spectrum at different wavelengths; designing a ratio of light reception areas of the optic sensor, the design being carried out in accordance with three aspects of “the response spectrum”“a fixed proportional relationship being present between multiplication of the optic response ratio and the light reception area and an output of light current” and “a proportional relationship being present between the light reception area and the output of the light current”; and obtaining light current outputs of identical proportions (such as 1:1:1) or in a desired ratio (meaning any arbitrary ratio other than 1:1:1, such as 1:2:1, 1:2:3, or 3:4:5) in accordance with the design of the previous step.
