Solution Overview
Problem
Existing turning processing devices lack a method to detect whether a turning target is properly held before initiating a turning process.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a turning target is mounted to a turning processing device without detection, then the mounting process is simple and fast, but the reliability of proper holding is uncertain and may lead to processing failures
Solution Approach 1:
A force sensor is introduced as an intermediary component between the pressing jig and the turning target. The force sensor detects the holding force during the mounting process, providing objective feedback on whether the turning target is properly held. This intermediary measurement system resolves the contradiction by enabling reliable detection without requiring complex overall system redesign.
Solution Approach 2:
The patent replaces subjective visual inspection or manual assessment of holding accuracy with objective force measurement. The force sensor converts mechanical holding conditions into measurable electrical signals, allowing precise quantification of holding force and automatic judgment of proper mounting, thereby improving reliability while keeping the mechanical mounting structure simple.
2Measurement precision
If a force sensor is added to detect holding force, then the reliability of detection is improved, but the device complexity and cost increase
Solution Approach 1:
The force sensor is integrated into the pressing jig structure, allowing the same component to serve both as a pressing mechanism and a measurement device. The pressing jig maintains its primary function of mounting the turning target while simultaneously enabling force detection through the integrated sensor, thus improving measurement precision without proportionally increasing device complexity.
Solution Approach 2:
The mounting device performs self-verification of proper holding through the force sensor. During the normal mounting operation, the force sensor automatically detects whether the holding force meets the required threshold, eliminating the need for separate verification steps or additional complex inspection equipment. The system serves itself by incorporating the detection capability directly into the mounting process.
