Reversible Leather Belt With Movable Loop and Unfolded End
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reversible belts are complex and cumbersome to manufacture and use, lacking a simple and efficient design that allows easy reversible wear.
Innovation Solution
A reversible leather belt design featuring a ribbon with a slit and a movable loop, where the buckle and prong are rotationally articulated at the free end, allowing the belt to be used reversibly with a thinned portion for the loop's translation and the prong's movement through the slit, simplifying manufacturing and use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a reversible belt is designed with a folded end and slot mechanism, then the belt can be worn with either side facing out, but the structure becomes complex and cumbersome to manufacture and use
Solution Approach 1:
The invention extracts the fold from the design by using a free unfolded end instead. The belt achieves reversibility through a slot and movable loop mechanism rather than folding the material, simplifying the manufacturing process while maintaining the reversible wear capability
Solution Approach 2:
Instead of folding the end to create reversibility, the invention inverts the approach by using a free end with a slot mechanism. The prong passes through the slot and the loop can be positioned on either side, achieving reversibility through the opposite structural arrangement
2Adaptability or versatility
If a reversible belt uses a folded end with slot mechanism, then the belt can be used reversibly, but it becomes cumbersome to use
Solution Approach 1:
The invention introduces dynamic elements by making the loop movable along the ribbon length and the prong rotatable through the slot. This dynamic design allows easy adjustment and reversal by simply moving the loop and rotating the prong, greatly improving ease of operation compared to fixed folded structures
Solution Approach 2:
The invention segments the belt structure into distinct functional zones: a free unfolded end for flexibility, a slot for prong movement, and a movable loop for positioning. This segmentation allows each component to perform its function independently, simplifying the reversal operation

AI summary
The invention relates to a reversible leather belt (1) comprising a ribbon (2) having a slot (10), a loop (3) mounted movable in translation, a buckle (4) mechanically fixed in rotation, and a prong (5) fixed in rotation and movable relative to the buckle and through the slot; the first end (8) of the ribbon is free and not folded, and the ribbon is provided with at least a first portion (11) having a first width, and at least a second portion (12) thinned having a second width less than the first width, extending from the first end, and joining the first portion, with the loop which is mounted movable in translation on the second thinned portion so as to be interposed between the buckle and the first portion of the ribbon, and which is accessible from both the first face of the ribbon and the second face of the ribbon.
