Tool Cover with Multi-Angle Locking Parts for Stable Hooking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held tools, such as reinforcing bar binding machines, face variability in user usage patterns due to hooks oriented towards the tool's center of gravity, leading to inconsistent handling and orientation changes when hooked on objects.
Innovation Solution
A tool design featuring multiple locking parts at different angles to accommodate the tool's center of gravity, allowing for hooks to be attached at varying angles and a cover that can be attached and detached, enabling consistent orientation and handling regardless of user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single hook attachment part is provided on the tool, then the structure is simple, but it cannot accommodate various usage patterns of individual users
Solution Approach 1:
The tool is divided into a main body part and a detachable cover part, with multiple hook attachment parts provided on the cover. This segmentation allows users to attach hooks at different locations and orientations to accommodate various usage patterns while keeping the main body structure simple.
Solution Approach 2:
The cover is designed to be detachable and replaceable, allowing dynamic reconfiguration of hook attachment parts. Users can attach and detach covers with different hook configurations depending on their specific usage needs, providing adaptability without permanently complicating the tool structure.
2Adaptability or versatility
If the hook opening faces toward the center of gravity of the tool, then the orientation remains stable when hooked, but it does not accommodate diverse user handling styles
Solution Approach 1:
By separating the hook attachment function into a detachable cover with multiple attachment parts, the tool allows users to select different hook orientations that maintain stability for their specific handling style, rather than forcing a single orientation for all users.
Solution Approach 2:
The cover with multiple hook attachment parts serves multiple functions: it provides stable hooking for various orientations, accommodates different user preferences, and can be detached or replaced. This multi-functionality resolves the contradiction between stability and adaptability.
3Adaptability or versatility
If multiple locking parts are provided at different angles, then various usage patterns are accommodated, but the manufacturing complexity increases
Solution Approach 1:
Multiple hook attachment parts are integrated into a separate cover component rather than being directly manufactured into the main tool body. This segmentation concentrates the complexity into a single detachable part, simplifying the manufacturing of the main tool while still providing multiple attachment options.
Solution Approach 2:
The cover serves as a universal interface that can be attached to the main body and provides multiple hook attachment functions. This approach allows the main body to be manufactured simply while the cover handles the complexity of accommodating various usage patterns.

AI summary
A tool includes a main body part, a gripping part connected to the main body part, and a plurality of locking part each provided at different angles to point at a center of gravity of the tool and each configured to fix a to-be-engaged object. The locking parts are provided on the main body part.
