Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple electrical connection is used between the medical sensor patch and sensing equipment, then the device complexity is reduced, but the reliability of the connection deteriorates due to patient movement causing disconnection
Solution Approach 1:
The connector employs a hinged connection between the first and second clamping members, allowing the structure to dynamically adapt to movement forces while maintaining electrical contact. The hinge enables the clamping members to flex and reposition themselves in response to patient movement, preventing disconnection without requiring an overly complex rigid structure.
Solution Approach 2:
The connector uses flexible clamping members that can deform and flex to accommodate movement between the medical sensor patch and sensing equipment. This flexibility allows the connector to maintain reliable electrical contact despite patient movement, resolving the contradiction between simple structure and connection stability.
2Reliability
If a secure clamping connection is implemented to prevent disconnection, then the reliability of electrical connection is improved, but the device complexity increases due to multiple clamping members and hinged connections
Solution Approach 1:
The connector combines multiple clamping members with a hinged connection into a single integrated assembly. The first and second clamping members are connected via a hinge, creating a unified structure that provides secure clamping while minimizing the number of separate components. This merging approach maintains reliability without proportionally increasing device complexity.
Solution Approach 2:
The hinged connection acts as an intermediary element between the first and second clamping members, allowing them to work together as a coordinated system. The hinge mediates the interaction between the clamping members, enabling them to apply clamping force effectively while adapting to movement, thus achieving secure connection with minimal structural complexity.
3Ease of operation
If the connector allows for patient movement, then the ease of operation is improved, but the electrical connection stability deteriorates due to straining on the connection
Solution Approach 1:
The connector is designed to be dynamic rather than static, with hinged connections that allow the structure to move and flex in response to patient movement. This dynamic design enables the connector to accommodate changes in position and orientation while maintaining electrical connection integrity, allowing patient freedom of movement without compromising connection stability.
Solution Approach 2:
The connector changes its physical parameters (position, orientation, degree of clamping) in response to patient movement through the hinged connection mechanism. This parameter adaptation allows the connector to maintain electrical contact stability while accommodating patient movement, resolving the contradiction between ease of operation and connection integrity.
