Hex Tool Spherical Joint for Confined Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Typical hex tools are rigid, limiting their accessibility and operability in confined spaces and restricted angles, necessitating a design that enhances accessibility and range of motion.
Innovation Solution
A hex tool with a spherical joint between the hex head and handle, allowing for increased range of motion and versatility by enabling the handle to rotate and swivel, which can be securely attached and detached for various applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rigid hex tool design is used, then the tool structure is simple and easy to manufacture, but the accessibility and range of motion are limited
Solution Approach 1:
The patent applies the dynamics principle by transforming the rigid, fixed-geometry hex tool into a dynamic system with a spherical joint mechanism. This joint allows the handle to rotate and pivot relative to the hex head, enabling the tool to adapt its orientation and reach screws in confined or awkwardly positioned spaces, thereby significantly improving accessibility and range of motion without compromising structural simplicity
2Adaptability or versatility
If a spherical joint is added to increase range of motion, then the operational flexibility is improved, but the device complexity increases
Solution Approach 1:
The patent employs the spheroidality principle by implementing a spherical joint mechanism that allows multi-directional rotation and pivoting. This spherical geometry enables the handle to move freely in multiple axes, providing operational flexibility and adaptability for accessing screws from various angles while maintaining a relatively simple and elegant mechanical structure
3Adaptability or versatility
If the handle is made detachable for versatility, then the adaptability to different applications is improved, but the device complexity and potential reliability issues increase
Solution Approach 1:
The patent applies the segmentation principle by dividing the hex tool into separable components: a hex head with spherical joint mechanism and a detachable handle. This segmentation allows the handle to be removed and replaced based on different application requirements, enhancing versatility. The design incorporates appropriate connection features that maintain reliable engagement during use while enabling easy detachment when needed
