Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If visual inspection is used to determine workpiece height, then no additional measuring equipment is needed, but the inspection process becomes time-consuming and inefficient
Solution Approach 1:
The patent replaces the manual visual inspection method with an automated optical measuring system. The height measuring device uses a sensor to automatically detect the position of the workpiece top surface and calculate height, substituting human visual judgment with precise mechanical-optical measurement equipment, thereby dramatically improving inspection efficiency and reducing time consumption.
Solution Approach 2:
The measuring device enables self-inspection of the workpiece height without requiring operator intervention. The sensor automatically detects the workpiece position, the processor calculates the height based on preset reference planes, and the system provides feedback, allowing the measurement process to serve itself without continuous human involvement.
2Measurement precision
If visual inspection is used to determine workpiece height, then the equipment remains simple, but measurement precision deteriorates due to human error
Solution Approach 1:
The patent replaces imprecise human visual inspection with a precise optical-sensor-based measurement system. The sensor detects the actual position of the workpiece top surface with high accuracy, and the processor calculates the height by comparing with the preset reference plane, eliminating human error and providing objective, repeatable measurements.
Solution Approach 2:
The patent introduces a sensor as an intermediary between the workpiece and the measurement system. The sensor acts as a mediator that converts the physical position of the workpiece top surface into an electrical signal, which is then processed to determine height, providing an accurate intermediate measurement step that bridges the gap between the workpiece and the evaluation system.
3Productivity
If automated measuring mechanisms are added to improve inspection speed, then productivity increases, but device complexity increases
Solution Approach 1:
The measuring device is designed with multi-functionality to justify its complexity. It can measure multiple workpieces sequentially, provide automated height calculation, display results, and control indicating lights for pass/fail judgment. This universal capability allows a single device to perform what previously required multiple manual operations, making the added complexity worthwhile for the productivity gain.
Solution Approach 2:
The system incorporates feedback mechanisms where the sensor detects workpiece height, the processor compares the measurement against preset standards, and the indicating lights provide immediate visual feedback on whether the workpiece passes or fails. This closed-loop feedback system automates the inspection decision-making process, improving productivity by eliminating manual measurement and judgment steps.

AI summary
A height measuring includes a mounting base, a measuring mechanism, and a controller. The measuring mechanism includes a driving member, a measuring member, and a sensor. The driving member is mounted onto the mounting base. The sensor is positioned on the driving member. The measuring member is movably positioned on the driving member and passes through the sensor. The driving member is configured to drive the measuring member to move until it contacts a workpiece in a jig. The controller is electrically connected to the sensor and prestores a moving distance range. The sensor is configured to sense a moving distance of the measuring member and transmit the moving distance to the controller. The controller is configured to judge whether or not the workpiece reaches a proper height relative to the jig by comparing the moving distance data with the prestored distance range.
