Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a pressure-bearing airbag with pressure sensor is added to measure punching force, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into the pad body: the pressure-bearing airbag serves both as a cushioning element for continuous punching and as a measurement medium for force detection. The pressure sensor is integrated directly into the airbag structure, merging detection and cushioning functions into a single component system, thereby reducing overall device complexity while maintaining measurement precision.
Solution Approach 2:
The patent uses pneumatic principles by incorporating a pressure-bearing airbag that responds to punching force through pressure changes. The airbag's elastic deformation under impact converts mechanical force into pressure variations that the pressure sensor can detect, providing an efficient and simple mechanism for force measurement without requiring complex mechanical linkages or electrical sensors.
2Reliability
If an air pump is added to maintain constant air pressure, then reliability is improved, but device complexity increases
Solution Approach 1:
The air pump is equipped with a pressure sensor that automatically detects when air pressure drops below a threshold level and activates the pump to replenish air. This self-regulating system maintains constant air pressure without requiring manual intervention or complex control mechanisms, improving reliability while keeping the control system simple through automatic feedback control.
Solution Approach 2:
The system implements a feedback loop where the pressure sensor continuously monitors airbag pressure and provides signals to the controller. When pressure drops, the controller activates the air pump to restore pressure to the desired level. This closed-loop feedback mechanism ensures reliable and stable air pressure maintenance with minimal complexity.
3Object-affected harmful factors
If a protective sleeve with foam buffer is added, then object-affected harmful factors are reduced, but device complexity increases
Solution Approach 1:
The protective sleeve with foam buffer is pre-installed on the pad body to provide cushioning protection before any punching occurs. This beforehand cushioning protects both the user's fist and the internal airbag from damage during continuous punching, reducing harmful impact effects while maintaining a simple layered structure that integrates seamlessly with the overall pad design.
4Ease of operation
If wall mounting features are added, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The wall mounting system is segmented into separate components: hanging packs with holes in the protective sleeve and Velcro belts attached to the back of the pad. This segmentation allows each component to be manufactured independently with standard tolerances, then assembled together to provide convenient wall mounting options without requiring high precision in any single manufacturing step.

AI summary
The invention patent discloses a punch power measurement device, comprises a device body and a measuring mechanism. In the center part of the device, there is a pressure-bearing airbag to be punched. The measuring mechanism includes an air-pressure sensor to test the pressure of the airbag, data processing and transmitting module, a power supply unit and importantly an air pump to keep constant working pressure of the airbag, and a silicon switch outside connected to the main board. The device can accurately test the punch power by measuring the pressure changes after each punch, and converting the data to specific figures in force unit based on our special algorithm. Signal output display is a screen or a wireless terminal such as smart phones, tablets and PCs etc. The key function of the air pump is to keep constant working pressure in the airbag without worrying about air leak.
