Pole Handle Loop Fastening With Tiltable Modular Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pole handles lack a simple and efficient mechanism for adjusting the size of the hand loop, which complicates assembly, repair, and limits modularity, while also failing to provide a secure fixation in the resting position.
Innovation Solution
A pole handle design featuring a loop fastening element that is tiltable about a rotational axis, allowing the hand loop to be adjusted in size between a resting and adjustment position, utilizing a non-positive connection for secure fixation and modular assembly, with a modular unit comprising the loop fastening element and hand loop separately attached to the handle core.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the loop is fastened using traditional mechanisms with multiple holes and pins, then the loop can be adjusted in size, but the assembly and repair processes become complicated and time-consuming
Solution Approach 1:
The handle is divided into a core component and a separate loop fastening element that can be independently assembled and disassembled. The loop fastening element includes a loop receiving region with a fastening element that can be attached to the core, allowing the loop to be adjusted or replaced without affecting the entire handle structure.
Solution Approach 2:
The loop fastening element is designed to be movable relative to the core, allowing it to be tilted or rotated into different positions. This dynamic design enables the loop to be easily adjusted in size by moving the fastening element along the strap, while also allowing for quick assembly and disassembly.
2Stability of the object's composition
If the loop fastening mechanism is integrated into the handle core, then the structure appears unified, but repair and replacement of the loop becomes difficult
Solution Approach 1:
The loop fastening element is designed as a separate component that can be independently removed from the handle core. This segmentation allows the loop to be replaced or repaired without damaging or disassembling the entire handle structure, while still maintaining a unified appearance when assembled.
Solution Approach 2:
The loop fastening element is designed to be easily discarded and replaced. The reversible connection allows the old loop to be quickly removed and a new loop to be attached, enabling rapid repair or upgrade of the loop mechanism without wasting the entire handle assembly.
3Adaptability or versatility
If different handle models use different loop mechanisms, then each model is optimized for its specific design, but production and storage processes become less efficient
Solution Approach 1:
The loop fastening element is designed as a universal component that can be used across different handle models. The standardized interface and reversible connection mechanism allow the same loop fastening element to be attached to various core designs, enabling production economies of scale while still accommodating model-specific requirements.
4Reliability
If the loop uses a positive connection mechanism, then the loop is securely fixed, but the adjustment mechanism becomes more complex
Solution Approach 1:
The loop fastening element incorporates a self-locking mechanism that automatically secures the loop in place through friction or geometric interlocking when the strap is pulled tight. This eliminates the need for additional positive connection elements like clips or buckles, maintaining secure fixation while keeping the mechanism simple.

AI summary
A pole handle having a central receiving area that receives a loop fastening element with a hand loop, which is secured to the loop fastening element and has an adjustable size. The loop fastening element and the hand loop is secured to the loop fastening element to form a modular unit which is formed separately from a core of the pole handle and which is secured to the core of the pole handle in a reversibly tiltable manner about a rotational axis in the pole handle. The loop fastening element can be tilted from a rest position, in which the loop fastening element is integrated into the surface contour of the handle head and in which the size of the hand loop cannot be adjusted, upwards about the rotational axis into an adjustment position, in which the size of the hand loop can be adjusted.
