Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple separate clamping force measuring devices are used to test different clamping devices, then measurement precision is maintained, but device complexity and cost increase significantly
Solution Approach 1:
The measuring device is designed with a universal measuring unit that can be used with different clamping devices through various adapter pieces. The measuring unit includes a force sensor, evaluation device, and energy store that can measure clamping forces for different types of clamping devices, eliminating the need for multiple separate measuring devices while maintaining measurement precision.
Solution Approach 2:
The measuring device is divided into a universal measuring unit and interchangeable adapter pieces. The measuring unit contains the expensive force sensor and evaluation electronics, while separate adapter pieces are designed for different clamping device types. This segmentation allows the expensive components to be reused across multiple applications.
2Measurement precision
If multiple separate clamping force measuring devices are used, then measurement precision is maintained, but cost increases due to duplicate expensive components
Solution Approach 1:
The measuring device is designed with a universal measuring unit that can be used with different clamping devices through various adapter pieces. The measuring unit includes a force sensor, evaluation device, and energy store that can measure clamping forces for different types of clamping devices, eliminating the need for multiple separate measuring devices while maintaining measurement precision.
Solution Approach 2:
The force sensor, evaluation device, and energy store are merged into a single integrated measuring unit that serves multiple clamping device types. This consolidation reduces the total number of expensive force sensors needed while maintaining the capability to measure different clamping forces.
3Measurement precision
If data is collected and processed on a central computer, then measurement precision is maintained, but administrative effort and time increase
Solution Approach 1:
The evaluation device in the measuring unit automatically evaluates measurement results in real-time during the measurement process. It compares measured clamping forces with predefined limit values and generates pass/fail assessments before the measurement session ends, eliminating the need for time-consuming post-measurement data processing on a central computer.
Solution Approach 2:
The measuring device performs self-evaluation of measurement results through the integrated evaluation device. It automatically determines whether measured clamping forces meet required specifications without requiring external computer processing, reducing administrative effort and time.
4Measurement precision
If multiple separate clamping force measuring devices are used, then measurement precision is maintained, but ease of operation decreases due to frequent charging
Solution Approach 1:
The force sensor, evaluation device, and energy store are merged into a single integrated measuring unit that serves multiple clamping device types. This consolidation reduces the total number of expensive force sensors needed while maintaining the capability to measure different clamping forces.
Solution Approach 2:
The measuring unit is designed as a portable, battery-powered system that can be dynamically moved between different clamping devices and work locations. The energy store provides sufficient operating time for multiple measurements without requiring frequent recharging, enabling flexible and continuous operation.
