Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wireless data communication system is used to connect the digital caliper with a slider to the control unit, then the ease of operation is improved, but the reliability deteriorates due to sensitivity to interferences and disturbances from other wireless communication systems
Solution Approach 1:
The patent introduces a wired connection interface as an intermediary between the digital caliper and the control unit, allowing data communication while eliminating wireless interference. This mediator approach resolves the contradiction by providing a reliable wired connection that avoids the harmful electromagnetic interferences affecting wireless communication reliability.
2Device complexity
If manual enabling procedure is required for thickness measurement, then the device complexity is reduced, but the ease of operation deteriorates and errors may occur due to manual intervention
Solution Approach 1:
The system automatically detects the presence of the digital caliper through the wired connection interface and enables thickness measurement without requiring manual intervention. The control unit self-configures when the caliper is connected, eliminating the need for operators to press dedicated start buttons and reducing the risk of measurement errors.
3Device complexity
If unit conversion between digital caliper and control unit is manually handled, then the device complexity is reduced, but the reliability deteriorates due to measurement unit discrepancies
Solution Approach 1:
The patent replaces manual unit conversion procedures with an automated electronic conversion system. The control unit automatically converts measurement units between the digital caliper and the control unit's preferred units through the wired data communication interface, eliminating errors associated with manual conversion while maintaining simple device architecture.
