Shoelace Attachment Bracket With Flexible Mounting for Stable Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attachment brackets for fastening items to shoes with shoelaces lack ease of installation and detachment, and often bend or flex excessively, leading to instability during use.
Innovation Solution
The attachment bracket features a first and second mounting bracket that can be pushed under the shoelaces from opposite directions, with a flexible section between them that can be bent, compressed, or stretched for easy installation and stabilization, and an item attached to the bracket stiffens this section to prevent bending and ensure secure fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the attachment bracket uses a rigid structure to prevent bending, then stability is improved, but ease of installation and detachment deteriorates
Solution Approach 1:
The attachment bracket is divided into two distinct segments: a rigid portion (mounting brackets) that provides stability and a flexible portion that enables easy installation and detachment. This segmentation allows each part to fulfill its specific function optimally without compromising the other.
Solution Approach 2:
Different parts of the attachment bracket have different mechanical properties - the mounting brackets are made rigid for stability while the intermediate portion is made flexible for ease of operation. This local differentiation of material properties resolves the contradiction between stability and ease of installation.
2Ease of operation
If the attachment bracket uses a flexible structure for easy installation, then ease of operation is improved, but stability during use deteriorates
Solution Approach 1:
The bracket is segmented into flexible and rigid zones, where the flexible zone enables easy installation while the rigid mounting brackets maintain stability during use. The segmentation ensures that flexibility is localized only where needed for installation.
Solution Approach 2:
The flexible portion is localized to the intermediate section of the bracket, while the mounting brackets that contact the shoe and item remain rigid. This local quality differentiation ensures flexibility where needed for installation while maintaining rigidity where stability is required.
3Reliability
If the attachment bracket has a complex structure to prevent bending, then stability is improved, but device complexity increases
Solution Approach 1:
Rather than creating a complex rigid structure throughout, the invention segments the bracket into simple rigid mounting brackets and a flexible intermediate portion. This segmentation achieves stability without requiring complex structural design.
Solution Approach 2:
The invention changes the material parameter (rigidity) of different portions of the bracket rather than complicating the overall structure. By making the intermediate portion flexible and the mounting brackets rigid, stability is achieved through material property selection rather than structural complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows for effortless attachment and detachment of items to the shoe, maintains stability by preventing bending, and is cost-effective due to its simple structure and manufacturing process.
Implementation Method 1
The part of the attachment bracket between the first mounting bracket and the attachment point of the second mounting bracket is flexible, whereby the part of the attachment bracket between the mounting brackets can be bent, compressed and/or stretched
Implementation Method 2
the piece that is fastened to the attachment bracket stiffens the part between the first and the second mounting brackets of the attachment bracket and, thus, prevents the attachment bracket from bending

AI summary
An attachment bracket for fastening an item to a shoe that is provided with a shoestring includes a bottom part, which can be fitted on top of the set of shoestrings, and a space for receiving the item. The attachment bracket also includes a first mounting bracket and a second mounting bracket that is spaced from the first mounting bracket. The mounting brackets can be pushed under the shoestring from opposite directions. In addition, the part of the attachment bracket between the first mounting bracket and the second mounting bracket is flexible.
