Sliding Locking Buckle with Sawteeth for Adjustable Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking buckles are either fixed in position or have limited sliding ranges, restricting their versatility and application in connecting items that require adjustable positioning.
Innovation Solution
A sliding-type locking buckle design featuring a casing with an upper and lower sliding slot, sawteeth, and a compression spring, allowing the locking buckle body to slide and stop at any position within a range by engaging sawteeth on the casing, with adjustable tooth width for varying sliding ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a common plastic locking buckle is used, then the structure is simple and cost is low, but the position is fixed and cannot slide
Solution Approach 1:
The locking buckle body is made movable within the casing through sliding slots, transforming the fixed position design into a dynamic adjustable position system. The compression spring enables the buckle body to move freely along the sliding slots, allowing continuous position adjustment rather than fixed positioning.
Solution Approach 2:
The locking buckle is divided into separate components: upper casing, lower casing, locking buckle body, and compression spring. This segmentation allows independent optimization of each part's function while maintaining overall simplicity, resolving the contradiction between adaptability and structural complexity.
2Adaptability or versatility
If a plastic locking buckle with sliding switch is used, then sliding function is achieved, but the sliding range is limited and cost is high
Solution Approach 1:
The complex sliding switch mechanism is completely removed from the design. Instead, the locking buckle body itself slides directly within the casing along sliding slots, achieving unlimited sliding range without requiring any additional sliding switch components or mechanisms.
Solution Approach 2:
The locking buckle body serves multiple functions: it provides the locking mechanism, enables sliding movement, and allows continuous position adjustment. This multi-functionality eliminates the need for separate sliding switch components, reducing device complexity while expanding sliding range.
3Adaptability or versatility
If a plastic locking buckle with sliding switch is used, then sliding function is achieved, but it can stop at only 2 or 3 stop positions rather than any position
Solution Approach 1:
The system transitions from discrete stop positions to continuous position adjustment. The locking buckle body can be positioned at any location along the sliding slots within the casing, providing infinite positioning options rather than limited stop positions, while maintaining structural simplicity.
4Adaptability or versatility
If the locking buckle body slides freely without guidance, then positioning flexibility is improved, but friction increases
Solution Approach 1:
Sliding slots are introduced as intermediary structures between the locking buckle body and the casing. These slots guide the movement of the buckle body, providing smooth sliding surfaces that reduce friction while maintaining positioning flexibility. The slots act as mediators that enable controlled movement with minimal resistance.
