Adjustable Closure Device for Motorcycling Garments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current closure devices for motorcycling clothing, such as buttons and zip fasteners, lack adjustability, making it difficult to precisely achieve a desired snugness of fit and require users to perform complex operations in hard-to-reach areas.
Innovation Solution
A closure device featuring a slider with a graduated scale that allows for adjustable positioning along a longitudinal guide, using hook-and-loop tape for secure attachment, enabling precise adjustment of the fastening between flaps, thus modifying the garment's snugness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If buttons or zip fasteners are used for closure, then the closure function is achieved, but adjustability of the fastening is lost
Solution Approach 1:
The closure device incorporates a dynamic adjustment mechanism where the second closure element can be repositioned along the flap border through a slider system. This allows the fastening position to vary dynamically rather than being fixed, enabling adjustment of the snugness of fit while maintaining a relatively simple overall structure.
Solution Approach 2:
The closure device is divided into separate functional elements: a first closure element fixed on one flap, a second closure element that can move on the other flap, and a slider mechanism. This segmentation allows independent adjustment of the closure position while keeping each component simple and manageable.
2Measurement precision
If tapes are used for adjusting snugness of fit, then adjustability is achieved, but precise restoration of desired fit level becomes difficult
Solution Approach 1:
The slider mechanism provides visual feedback through its position along the flap border, allowing the user to see exactly where the closure element is located. This enables precise restoration of a desired fit level by returning the slider to a previously noted position, combining measurement precision with ease of operation.
Solution Approach 2:
The system creates a reproducible configuration by allowing the slider to be positioned and repositioned at specific locations along the flap. This copying capability enables the user to restore a previously successful fit level precisely by returning the closure element to the same position.
3Measurement precision
If complex adjustment mechanisms are used, then precise adjustment is achieved, but user convenience deteriorates
Solution Approach 1:
The closure device enables the user to perform the adjustment themselves through a simple slider mechanism that can be easily moved and fixed at desired positions. The system is designed to be user-operable without requiring specialized tools or complex procedures, maintaining precision while ensuring ease of operation.
Solution Approach 2:
The slider acts as an intermediary element between the fixed first closure element and the movable second closure element. This mediator provides a simple interface for the user to adjust the closure position precisely without dealing with complex mechanisms, improving both precision and user convenience.
4Adaptability or versatility
If the second closure element is fixed on the flap border, then structural simplicity is maintained, but adjustability of snugness of fit is lost
Solution Approach 1:
The second closure element is made dynamic by allowing it to move along the flap border through a slider mechanism. This dynamic positioning capability provides adjustability of snugness of fit while adding only minimal structural complexity compared to a fixed closure system.
