Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a buffer pad is compressed to increase rigidity for impact protection, then protective performance is improved, but the compression rate becomes difficult to control precisely
Solution Approach 1:
The patent changes the physical state and parameters of the buffer pad by controlling compression rate. Different compression rates (10%, 20%, 30%, etc.) create different rigidity levels, allowing the buffer pad to be optimized for specific protection requirements while maintaining precise control through the evaluation jig's standardized compression mechanism.
Solution Approach 2:
The evaluation jig introduces dynamic testing capability by applying controlled compression forces and measuring the buffer pad's response. This allows real-time assessment of how the buffer pad's rigidity changes with compression rate, enabling precise selection of the optimal compression rate for each application scenario.
2Measurement precision
If existing evaluation methods are used, then basic buffer pad performance can be assessed, but dynamic rigidity measurement at varying compression rates is not achievable
Solution Approach 1:
The evaluation jig is designed with dynamic testing capabilities that allow compression rate to be varied during measurement. The system can apply different compression forces and measure the corresponding dynamic rigidity values, enabling comprehensive characterization of the buffer pad's mechanical properties across its operating range.
Solution Approach 2:
The jig enables systematic variation of compression rate parameters (10%, 20%, 30%, etc.) while measuring dynamic rigidity responses. This parameter-based evaluation approach provides precise measurement data that reveals how buffer pad rigidity evolves with compression, supporting optimized selection for different protection requirements.
3Strength
If buffer pad rigidity is increased for better impact resistance, then protection performance is improved, but the buffer pad becomes less adaptable to different compression scenarios
Solution Approach 1:
The evaluation jig enables dynamic assessment of buffer pad performance across multiple compression rates. By measuring how rigidity changes with compression (10%, 20%, 30%, etc.), the system identifies the optimal compression rate that balances impact resistance with adaptability, allowing the buffer pad to be tuned for specific application requirements rather than being overly rigid in all conditions.

AI summary
The present invention relates to a jig for evaluating a buffer pad. The jig includes a first plate configured to be positioned on one surface of the buffer pad and configured to press the buffer pad; a second plate configured to be positioned on another surface of the buffer pad and configured to press the buffer pad from the other surface; and a magnet member configured to be positioned between the first plate and the second plate. A recessed portion, which is recessed to allow the magnet member to be disposed, is defined at an edge of at least one of the first plate and the second plate.
