Flexible Housing Remote Wrench Torque Transfer Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote wrenches suffer from inefficiencies in torque transfer due to frictional losses and rigid housings, which reduce the torque applied to inaccessible areas and complicate the rotation process.
Innovation Solution
A flexible housing with a support and base system that acts as a cantilever beam, enhancing torque transfer efficiency and allowing greater maneuverability by reducing load on the torque transfer system and increasing the wrench's strength and fatigue life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid housing is used in a remote wrench, then the structural strength is improved, but the torque transfer efficiency deteriorates due to frictional losses and load on the torque transfer system
Solution Approach 1:
The patent replaces the rigid housing with a flexible housing that allows the internal components to move relative to the housing during operation. This flexibility reduces the load on the torque transfer system (chain and sprockets) and minimizes frictional losses, thereby improving torque transfer efficiency while maintaining sufficient structural strength through proper material selection and design
Solution Approach 2:
The patent changes the physical parameter of the housing from rigid to flexible, which fundamentally alters how forces are transmitted through the system. This parameter change reduces the stiffness of the housing structure, allowing it to deform slightly under load and thereby reduce the burden on the torque transfer components, improving overall efficiency
2Adaptability or versatility
If a remote wrench is positioned at an angle to the ratchet wrench, then access to difficult to reach areas is improved, but the ease of operation deteriorates as it becomes difficult to rotate the ratchet wrench without supporting the remote wrench
Solution Approach 1:
The flexible housing allows the remote wrench assembly to accommodate angular positions more easily. When the remote wrench is positioned at an angle, the flexible housing can deform to absorb some of the operational forces, allowing the user to rotate the ratchet wrench without needing to support the remote wrench, thereby improving ease of operation while maintaining adaptability to difficult access areas

AI summary
Methods and systems for increasing the efficiency of a remote wrench. The remote wrench can include a flexible plate within the tool housing or as part of the housing that is more flexible than the rigid housing in conventional remote wrenches that has been shown to limit efficiency. Additionally, a fixed support and a base can be provided that are collectively capable of being coupled to the remote wrench, preferably at the flexible plate, to increase efficiency. The remote wrench operation is therefore improved by reducing inefficiencies and providing a maximum torque output.
