Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed fixture is used to maintain the distance between the detector fiber and the skin, then the initial positioning is accurate, but the detection accuracy deteriorates when the test subject moves or when different sized subjects are measured
Solution Approach 1:
The patent applies the dynamics principle by replacing the fixed fixture with a flexible cushioning member that can dynamically adapt its shape and position. The cushioning member deforms to conform to the test subject's body surface, maintaining optimal contact between the detector fiber and the skin regardless of subject size, shape, or movement. This dynamic adaptation resolves the contradiction between maintaining precise initial positioning and accommodating variations in test subjects.
Solution Approach 2:
The patent changes the physical state and properties of the positioning system by introducing a cushioning member with specific elastic properties. The cushioning member's ability to deform and recover allows the system to adjust the distance and contact pressure between the detector fiber and skin in real-time, optimizing fluorescence detection across different subjects and conditions while eliminating the need for multiple fixed fixtures.
2Measurement precision
If multiple specialized fixtures are prepared for different test subjects and body parts, then detection accuracy for each subject is maintained, but the device complexity and cost increase
Solution Approach 1:
The patent applies universality by designing a single detection device with a cushioning member that can accommodate various test subjects and body parts. The cushioning member's adaptive nature allows one fixture to replace multiple specialized fixtures, maintaining detection accuracy across different applications while reducing device complexity and cost.
Solution Approach 2:
By changing the physical properties of the positioning system to include a deformable cushioning member, the patent enables a single fixture to adapt to different subjects and measurement requirements, eliminating the need for multiple specialized fixtures and thereby reducing overall device complexity.
3Stability of the object's composition
If the detection device maintains constant contact with the skin, then positioning stability is achieved, but the system cannot adapt to subject movement or size variations
Solution Approach 1:
The patent changes the mechanical properties of the contact interface by introducing a cushioning member with specific elastic characteristics. This allows the system to maintain stable contact through the cushioning member's deformation and recovery, while simultaneously adapting to subject movement and size variations, resolving the contradiction between stability and adaptability.
