Adjustable Belt with Segmented Buckle Loop for Fine Fit Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dress belts with adjustable buckle holes often fail to provide precise fit adjustments, as the standard inch increments result in either too tight or too loose fits, and spacing buckle holes too close can lead to belt damage.
Innovation Solution
An adjustable belt design featuring a buckle loop with a securing mechanism of studs and holes allows for varying the length of the overlapping portion, enabling fine adjustments in belt size by relocating studs between spaced holes, thereby adjusting the buckle loop size and belt length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the buckle holes are spaced an inch apart along the belt, then the belt provides adjustable length in standard increments, but the adjustment precision is too coarse resulting in either too tight or too loose fits
Solution Approach 1:
The belt adjustment system is segmented into two independent components: (1) traditional buckle holes in the tongue for coarse adjustment, and (2) a separate series of holes in the overlapping portion for fine adjustment. This segmentation allows each component to serve a specific adjustment function, achieving both coarse and fine control without compromising either adjustment precision or ease of operation.
Solution Approach 2:
The invention adds a second dimension of adjustment by introducing the overlapping portion with its own series of holes, perpendicular to the traditional buckle hole arrangement. This creates a two-stage adjustment process where the user first selects the buckle hole and then adjusts the overlapping portion, effectively adding an additional adjustment degree of freedom.
2Measurement precision
If the buckle holes are spaced closer together to improve adjustment precision, then the fit precision improves, but the belt structure becomes vulnerable to damage with the prong ripping between holes
Solution Approach 1:
The adjustment function is segmented between two separate structures: the traditional buckle holes remain spaced at safe intervals to maintain belt integrity, while the fine adjustment holes are created in the overlapping portion. This segmentation allows precise adjustment without compromising the structural strength of the main belt body.
Solution Approach 2:
The overlapping portion acts as an intermediary element between the buckle and the belt end. It provides the fine adjustment function through its own series of holes, while the traditional buckle holes maintain their original spacing to preserve belt strength. The intermediary overlapping portion absorbs the fine adjustment function, protecting the main belt structure from damage.
3Adaptability or versatility
If the overlapping portion length is varied to adjust belt length, then the belt size adjustability improves, but the buckle loop size varies requiring a capturing mechanism
Solution Approach 1:
The overlapping portion serves multiple functions: (1) it provides the fine adjustment of belt length through varying its length, (2) it forms the buckle loop that captures the buckle, and (3) it provides the second series of holes for precise positioning. This multi-functionality achieves versatile belt size adjustment while managing the complexity through a unified structural design.

AI summary
An adjustable best for wear about a waist of a person is provided. The adjustable belt includes an overlapping portion that is folded back to form a buckle loop, a buckle captured by the buckle loop and a securing mechanism that secures the overlapping portion of the belt folded back. The belt has a length or a size which is adjustable by varying the length of the overlapping portion. The securing mechanism belt may include one or more studs receivable in one or more holes.
