Tapered Shaft Charm Mount for Footwear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing footwear customization methods lack a secure and aesthetically pleasing way to attach charms or decorations to footwear, often resulting in charms being in direct contact with the footwear surface, which can lead to trapping of granular materials and difficulty in cleaning.
Innovation Solution
A device comprising a tapered shaft with a fixed footwear holder at one end and a fixed charm mount at the other, secured by a floating washer that allows the device to be securely attached to both the inner and outer surfaces of the footwear, elevating the charm above the footwear surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a charm is attached directly to the footwear surface, then the attachment method is simple, but granular materials can be trapped and cleaning becomes difficult
Solution Approach 1:
The charm is elevated from the footwear surface to a higher dimension using a vertical shaft structure. The charm mount positioned at the top of the shaft creates vertical separation between the charm and footwear surface, preventing granular material accumulation while maintaining secure attachment.
Solution Approach 2:
The shaft and floating washer assembly acts as an intermediary structure between the charm and footwear. This mediator elevates the charm above the footwear surface, creating a gap that prevents granular material trapping while maintaining secure attachment through the floating washer's gripping mechanism.
2Stability of the object's composition
If a fixed structure is used to attach the charm, then the charm position is stable, but the device cannot accommodate various aperture sizes in footwear
Solution Approach 1:
The floating washer is designed to move dynamically along the shaft rather than being fixed at a specific position. This dynamic positioning allows the washer to settle at different locations depending on the aperture size, enabling the device to adapt to various footwear aperture dimensions while maintaining stable charm attachment.
Solution Approach 2:
The device accommodates various aperture sizes by changing the positional parameter of the floating washer along the shaft. The washer's movable position allows the attachment mechanism to adjust to different aperture dimensions while maintaining secure attachment and stable charm positioning.
3Volume of moving object
If the charm is positioned close to the footwear surface, then the device structure is compact, but the charm display prominence is reduced
Solution Approach 1:
The charm is positioned in a higher vertical dimension above the footwear surface using the shaft structure. This vertical elevation increases the charm's prominence and visibility without significantly increasing the horizontal footprint of the device, achieving both compactness and display prominence.
