Adjustable Cord Lock Buckle with Self-Locking Teeth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional belts often provide an ill-fitting experience due to fixed sizes and bulky designs, leading to discomfort and limited adjustability.
Innovation Solution
A cord locking apparatus featuring a buckle with an eyelet that includes concentric teeth or edges, allowing the cord to pass through parallel to the central axis and locking when the cord is perpendicular, enabling adjustable tension and fit without moving parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional belts use fixed-size buckles with discrete holes, then manufacturing is simple, but adaptability to different waist sizes is poor
Solution Approach 1:
The belt system transitions from a static fixed-hole buckle to a dynamic adjustable cord system where the cord can be positioned at different angles relative to the buckle eyelet, enabling continuous size adjustment rather than discrete fixed positions
Solution Approach 2:
The invention changes the parameter of cord angle relative to the buckle eyelet (from fixed to variable), allowing the same buckle structure to accommodate different waist sizes by adjusting the cord angle between 0-90 degrees
2Ease of operation
If traditional belts use bulky straps and buckles, then structural strength is sufficient, but comfort and ease of operation deteriorate
Solution Approach 1:
The invention extracts the adjustment mechanism from a bulky traditional buckle structure and replaces it with a minimalistic cord-and-eyelet system, removing unnecessary bulk while retaining adjustment functionality
Solution Approach 2:
The invention uses a thin, flexible cord instead of a rigid bulky strap, allowing the belt to conform to the user's waist shape while maintaining sufficient strength through the cord locking mechanism
3Ease of operation
If traditional belts lack adjustment mechanisms, then device complexity is low, but ease of operation for on-the-go adjustment is poor
Solution Approach 1:
The belt system provides self-service adjustment capability where the user can independently adjust the cord angle and position without requiring tools or assistance, enabling on-the-go size changes
Solution Approach 2:
The adjustment mechanism is made dynamic and continuous rather than static and discrete, allowing smooth adjustment at any point along the cord length and angle range
4Measurement precision
If traditional belts use fixed discrete sizes, then manufacturing precision requirements are low, but measurement precision for fit is poor
Solution Approach 1:
The invention changes from discrete size parameters (fixed holes) to continuous parameters (cord angle and position), enabling precise fit adjustment while using standard manufacturing tolerances for the buckle and cord components

AI summary
An article of clothing in the form of a belt includes: a cord having a proximal end and a distal end; and a buckle having an eyelet and a locking feature; wherein the buckle is attached to the proximal end and the distal end of the cord is configured to pass through the buckle eyelet; and the locking feature is structured and arranged to selectively lock and unlock movement of the cord through the buckle.
