Ergonomic Hand Tool for Component Installation Force Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for installing components, such as plugs or clips, often require excessive force and strain on the thumb or other fingers, leading to discomfort and potential injury.
Innovation Solution
A tool designed to be worn on the hand, featuring a connecting portion between two fingers, an installing portion supported on one side of the fingers, and a supporting portion that can be embraced by the fingers, allowing for the distribution of installation force across the palm and fingers, thereby reducing strain on any single joint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional manual installation methods are used, then installation can be performed with simple tools, but excessive force and strain are applied to the thumb and fingers leading to discomfort and potential injury
Solution Approach 1:
The patent introduces an intermediary installation tool that mediates between the user's hand and the component being installed. The tool distributes installation force across multiple fingers and the palm through its T-shaped structure, preventing excessive strain on any single joint while maintaining effective component installation capability.
2Productivity
If excessive force is applied to install components, then installation can be completed quickly, but strain and potential injury occur on the thumb and fingers
Solution Approach 1:
The installation tool segments the force application across multiple contact points on the hand (palm and multiple fingers) rather than concentrating it on a single digit. This segmentation allows effective installation force to be applied without overloading any individual joint, maintaining productivity while preventing injury.
3Ease of operation
If the tool is designed to distribute force across the palm and fingers, then ergonomic comfort is improved, but device complexity increases
Solution Approach 1:
The tool implements local quality by creating specific geometric features (the T-shaped structure with perpendicular extensions) that naturally direct and distribute forces to optimal locations on the hand. This localized structural design achieves effective force distribution without requiring complex mechanisms or multiple components.
