Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If precision calibration is done inside the jacket by inserting or removing spacers, then measurement precision is improved, but device complexity and loss of time increase due to required disassembly and reassembly
Solution Approach 1:
The spacer is pre-positioned outside the jacket at a predetermined location that corresponds to the desired pressure calibration point. This eliminates the need for disassembly and reassembly during calibration, as the spacer's position is established in advance and simply needs to be engaged with the piston during operation.
Solution Approach 2:
The spacer acts as an intermediary element that translates a simple external positioning operation into precise internal calibration. By positioning the spacer externally at a predetermined location, the complex internal calibration process is simplified while maintaining measurement precision.
