Freely Spliced Buckle Strap with Transverse Convex Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current watchbands are inconvenient to adjust in length and do not meet modern society's requirements for fashionable and novel appearance, as they require a special screwdriver for adjustment.
Innovation Solution
A freely spliced buckle strap system with clamping protrusions and grooves, featuring transverse convex strips for easy assembly and disassembly without tools, allowing for adjustable length and integration of buckle units with different lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a special screwdriver is used to adjust the strap length, then the connection is reliable, but the ease of operation deteriorates
Solution Approach 1:
The strap is divided into multiple detachable buckle units that can be freely combined. Each unit has standardized clamping protrusions and grooves that enable tool-free assembly while maintaining connection reliability through the clamping mechanism with transverse convex strips.
Solution Approach 2:
The clamping structure is designed to be self-operating without requiring external tools. The clamping protrusion automatically engages with the clamping groove, and the transverse convex strips provide self-locking functionality that maintains connection reliability while enabling easy user adjustment.
2Ease of operation
If the strap structure is simplified for easy adjustment, then the ease of operation improves, but the device complexity increases due to additional components
Solution Approach 1:
The buckle units are designed with universal interfaces that can connect to various strap types and configurations. The standardized clamping protrusion and groove design allows the same component to serve multiple connection purposes, reducing overall system complexity despite enabling tool-free adjustment.
Solution Approach 2:
The clamping structure uses nested components where the transverse convex strips are integrated within the clamping protrusion and groove structures. This nesting approach allows multiple functional elements to be compactly arranged, minimizing the increase in device complexity while providing tool-free adjustment capability.
3Adaptability or versatility
If multiple buckle units are spliced together, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The strap system is segmented into standardized buckle units that can be independently selected and combined. Each unit has identical connection interfaces, allowing users to create various configurations by simply repeating the same modular component, which increases adaptability without proportionally increasing complexity.
Solution Approach 2:
All buckle units use homogeneous connection structures with matching clamping protrusions and grooves. This uniformity across all units simplifies the assembly process despite allowing multiple units to be combined, as users only need to understand one connection type to assemble any configuration.

AI summary
The disclosure concerns a freely spliced buckle strap, at least two buckle units and a buckle connection structure; the buckle connection structure includes a clamping protrusion and a clamping groove, and a first transverse convex strip is provided on or closed to the clamping protrusion; the clamping groove is provided with a second transverse convex strip that can be matched, clamped and locked with the first transverse convex strip; two adjacent buckle units are placed in the clamping groove of the other buckle unit, and are reliably connected to form a whole through the match, clamping and locking by the first and second transverse convex strips.
