Adjustable Hook Mounting for Portable Tool Handles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable tools with hooks lack the ability to change the hook's position between the left and right sides of the handle and adjust the distance between the hook and the handle, limiting their operability.
Innovation Solution
A hook system with a U-shaped hook body and a hook holder that allows the hook to be positioned on either side of the handle and adjusted in distance by pinching the extension arms to change the position and distance, using resilient support legs that can be moved into different recesses to secure the hook in various configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hook is fixed at a specific position on the handle, then the structure is simple and reliable, but the hook cannot be adjusted to different positions or sides of the handle
Solution Approach 1:
The hook mounting structure transitions from a fixed position to a dynamic, adjustable position system. The hook body can be moved between left and right sides of the handle, and the distance from the handle can be adjusted by pressing the extension arms, allowing the hook to adapt to different carrying needs while maintaining a relatively simple overall structure.
Solution Approach 2:
The hook is divided into separable components: the hook body, extension arms, and support legs. This segmentation allows the hook to be disassembled and reconfigured at different positions on the handle, enabling position adjustment without requiring a completely different mounting structure for each position.
2Volume of moving object
If the hook is positioned close to the handle, then the hook occupies less space and is more compact, but the hook cannot accommodate thicker objects or provide sufficient hanging clearance
Solution Approach 1:
The distance between the hook and the handle is made adjustable rather than fixed. By pressing the extension arms, the hook can be moved closer to the handle for compact storage or pulled farther away to accommodate thicker objects like belts or stepladders, providing flexibility in space occupation.
Solution Approach 2:
The physical parameter of distance between the hook and handle can be changed by the user. The extension arms allow the hook to be positioned at different distances from the handle, adapting the spatial parameter to match different carrying requirements and object thicknesses.
3Ease of operation
If the hook is positioned on the left side of the handle, then the hook does not interfere with right-handed operation, but the hook cannot be used for left-handed operation or positioned on the right side
Solution Approach 1:
The hook position is made dynamic rather than fixed. The hook body can be moved between the left and right sides of the handle by adjusting the extension arms, allowing the same hook structure to serve different operational needs and prevent interference regardless of the operator's hand preference.
Solution Approach 2:
The hook mounting structure is designed with asymmetric flexibility, allowing the hook to be positioned on either the left or right side of the handle. This asymmetric design capability provides the adaptability needed to accommodate different operational styles while maintaining a relatively simple symmetric mounting mechanism.

Function Achieved in This Case
Enables the hook to be easily mounted on either side of the handle and adjusted in distance, improving operability by allowing secure attachment to different objects, such as belts or stepladders, and enhancing usability based on the object's thickness.
