Solution Overview
Problem
Existing torque-sensing and transmitting devices face issues with vibration damage to electronic elements due to the direct attachment of the torque-sensing output system on a rib structure, leading to maintenance costs and potential damage from transmitted vibrations during tightening processes.
Innovation Solution
A torque-sensing and transmitting device with a vibration-damping structure, incorporating elastic vibration-damping members and layers that reduce vibration transmission through indirect contact with the transmission body, and elastic clamping of the circuit board and battery modules between inner and outer casings, preventing direct contact and thus minimizing damage from vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the torque-sensing output system is directly attached and fixed on the rib structure, then the device structure is simple and manufacturing cost is low, but vibrations are directly transmitted to the electronic elements causing damage and reduced reliability
Solution Approach 1:
The patent introduces a vibration-damping structure as an intermediary component between the rib structure and the torque-sensing output system. This mediator absorbs and dampens vibrations before they reach the electronic elements, protecting them from damage while maintaining overall structural simplicity.
Solution Approach 2:
The vibration-damping structure is pre-installed between the rib structure and the electronic elements to provide beforehand cushioning against vibrations. This preventive measure protects the electronic elements from vibration damage before the damage can occur, enhancing reliability without significantly increasing complexity.
2Reliability
If elastic material is used to cover and secure all related electronic elements by means of adhesive or filling, then electronic elements are protected from vibration damage, but internal damaged elements cannot be fixed due to the elastic material being interposed between the tiny gaps
Solution Approach 1:
The patent segments the protection approach by using a structured vibration-damping design that does not completely enclose the electronic elements. This segmentation allows vibration protection while maintaining access to electronic elements for repair and maintenance, resolving the contradiction between protection and maintainability.
3Strength
If adhesive or filling is used to fix electronic elements to the rib structure, then the electronic elements are secured against vibration, but maintenance costs increase due to inability to access damaged elements
Solution Approach 1:
The vibration-damping structure serves as an intermediary that provides mechanical coupling and vibration damping without using adhesive or filling that would permanently bond the electronic elements. This allows the electronic elements to remain securely fixed while accessible for maintenance, reducing maintenance costs.
