Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pressure sensing buttons are used to achieve high sensitivity, then sensing capability is improved, but false touches increase
Solution Approach 1:
A thermal conductive film is introduced as an intermediary between the pressure sensing element and the environment. This film enables temperature sensing functionality while maintaining pressure sensing capability, allowing the system to distinguish between genuine touches and false touches through temperature verification
Solution Approach 2:
The sensing module integrates both pressure sensing and temperature sensing functions into a single device. The pressure sensing element detects pressure while the temperature sensing element (with first, second, third and fourth temperature sensing parts) monitors temperature, creating a multi-functional system that can differentiate between real and false touches

AI summary
A sensing module includes a temperature sensing element, a pressure sensing element surrounded by the temperature sensing element, and a thermal conductive film covering the temperature sensing element. The temperature sensing element includes a first temperature sensing part, a second temperature sensing part, a third temperature sensing part and a fourth temperature sensing part. The first temperature sensing part and the second temperature sensing part are arranged in a first direction. The third temperature sensing part and the fourth temperature sensing part are arranged in a second direction. The first direction is different from the second direction. The pressure sensing element includes a pressure sensing upper part and a pressure sensing lower part. The pressure sensing upper part and the pressure sensing lower part are arranged in a third direction, where an acute angle is formed between the third direction and the first direction.
