Lace Wrap Ring Segmented Eyelet Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for clothing and footwear, such as eyelets and loopholes, often require robust solutions that combine the functionality of both to securely fasten items, but lack a unified design that efficiently integrates lace wrapping and secure attachment.
Innovation Solution
A lace wrap ring comprising a first eyelet with a head and shank, a washer, and a second eyelet with a snapping shank mechanism, allowing lace winding and secure coupling, which can function as both an eyelet and a loophole for enhanced fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a robust eyelet is made with metal head and shank folded to secure to fabric, then strength and reliability are improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The fastening system is divided into two separate eyelet components (first eyelet and second eyelet) that are inserted from opposite sides of the material. Each eyelet has its own head and shank, allowing independent insertion and simplifying installation while maintaining robust fastening through the combination of both components.
Solution Approach 2:
The second eyelet is nested within the first eyelet, with the shank of the second eyelet inserted through the head of the first eyelet. This nested arrangement creates a compact, integrated fastening structure that combines both eyelets into a unified robust connection point.
2Ease of operation
If loopholes are used for fastening items of clothing and footwear, then ease of operation is improved, but strength and reliability deteriorate
Solution Approach 1:
The invention merges the features of eyelets (providing structural strength with heads and shanks) with the functionality of loopholes (allowing lace passage and wrapping). The resulting lace wrap ring combines the robustness of eyelet construction with the operational simplicity of loophole-style lacing.
Solution Approach 2:
The combined eyelet-loophole structure serves multiple functions: it provides a strong anchoring point like an eyelet, allows lace passage like a loophole, and enables lace wrapping around the outer shank for enhanced fastening. This multi-functional design eliminates the need to choose between strength and ease of operation.
3Ease of operation
If lace is allowed to touch the ground, then convenience is improved, but hygiene and durability deteriorate
Solution Approach 1:
The lace wrap ring extends the fastening structure outward from the material surface by allowing lace to wrap around the outer shank. This creates an elevated termination point for the lace, raising it above the ground level and preventing contact with contaminants while maintaining full lace functionality.
