Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a flexible connector is used to link the display screen and control card, then the device can be assembled with simpler geometry and lower cost, but the connector deforms during assembly leading to unreliable electrical contact
Solution Approach 1:
The patent applies preliminary action by implementing a compression checking means that verifies the compression state of the flexible connector before final assembly is completed. The checking means detects whether the flexible connector has been properly compressed during the assembly process, allowing operators to correct compression issues before they lead to contact failures. This advance verification prevents unreliable electrical contact while maintaining the benefits of flexible connectors.
2Reliability
If the flexible connector is compressed to ensure electrical contact, then contact reliability improves, but the connector may deform or break during assembly
Solution Approach 1:
The patent implements feedback by using a compression checking means that provides real-time information about the compression state of the flexible connector during assembly. The checking means monitors the compression level and provides feedback to operators, allowing them to adjust the compression force to achieve reliable electrical contact without exceeding the connector's structural limits. This feedback mechanism prevents over-compression that could cause deformation or breakage while ensuring sufficient compression for reliable contact.
3Reliability
If rigid connectors are used instead of flexible connectors, then electrical contact reliability improves, but the device becomes more cumbersome and expensive
Solution Approach 1:
The patent applies preliminary action by implementing a compression checking means that verifies the compression state of the flexible connector before final assembly is completed. The checking means detects whether the flexible connector has been properly compressed during the assembly process, allowing operators to correct compression issues before they lead to contact failures. This advance verification prevents unreliable electrical contact while maintaining the benefits of flexible connectors.
4Ease of operation
If the flexible connector is made more accessible for repositioning, then assembly ease improves, but the device geometry becomes more complex
Solution Approach 1:
The patent applies preliminary action by implementing a compression checking means that verifies the compression state of the flexible connector before final assembly is completed. The checking means detects whether the flexible connector has been properly compressed during the assembly process, allowing operators to correct compression issues before they lead to contact failures. This advance verification prevents unreliable electrical contact while maintaining the benefits of flexible connectors.
