Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional operating devices with a tilting operating shaft struggle to detect motions in multiple directions, such as translation in the radial direction and rotation about the center, limiting the device's operational flexibility.
Innovation Solution
The operating device incorporates a movable body and a base body with sensors to detect forces acting on the base body, allowing the operating shaft to move in various directions, including translation, rotation, and tilt, by using elastic bodies that deform in the axial direction to measure motion without requiring additional deformation in other directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotatable support shaft is used to detect operating shaft motion, then the tilting direction and magnitude can be calculated, but the number of detectable motion types is limited
Solution Approach 1:
The patent replaces the mechanical rotational detection system with force sensing elements that directly measure applied forces in multiple directions. Instead of converting all motions to rotation for detection, the invention uses sensors to directly detect forces along the axial direction and perpendicular forces, enabling detection of translation, rotation, and tilting through force measurements rather than mechanical coupling.
Solution Approach 2:
The force sensing elements serve multiple detection functions simultaneously. A single force sensing structure can detect axial forces, perpendicular forces, and by combining these measurements, determine both translational displacement and rotational angle of the operating shaft, making the detection system multi-functional without requiring separate mechanisms for each motion type.
2Adaptability or versatility
If elastic bodies are arranged to deform in multiple directions for detecting multi-directional motion, then detection capability increases, but the layout complexity of elastic bodies increases
Solution Approach 1:
The patent replaces complex multi-directional elastic deformation arrangements with force sensing elements that directly measure forces. Instead of arranging elastic bodies to deform in multiple directions to infer motion, the invention uses force sensors to directly detect the forces applied, simplifying the elastic body layout while maintaining comprehensive detection capability.
Solution Approach 2:
The force sensing elements act as intermediaries between the operating shaft and the detection system. Rather than using elastic bodies to mechanically couple and transmit multi-directional motion information, the force sensors directly measure the forces applied to the operating shaft, providing a simpler intermediary mechanism that enables comprehensive motion detection.
