Sliding Elastic Belt Attachment for Hidden Longitudinal Stretch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing belts with elastic inserts compromise aesthetic appeal and durability, and are difficult to construct, while conventional belts lack longitudinal elasticity.
Innovation Solution
An elastic attachment comprising an outer body with an inner compartment and a sliding inner body held by elastic means, allowing the belt to extend and retract without visible elastic components, compatible with various buckle types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If elastic inserts are integrated into the belt body, then longitudinal elasticity is improved, but aesthetic appearance deteriorates
Solution Approach 1:
The belt is divided into two separate functional parts: a rigid belt body for aesthetic appearance and an independent elastic attachment for longitudinal elasticity. The attachment includes an outer body and an inner body that can slide relative to each other, with the elastic means housed in a housing on the inner body. This segmentation allows each part to fulfill its specific function without compromising the other.
Solution Approach 2:
The elastic attachment acts as an intermediary component between the belt body and the buckle. It includes a front part that connects to the belt body and a rear part that connects to the buckle, with the elastic means positioned in between. This intermediary structure transmits the elastic function while keeping the belt body itself unchanged and aesthetically pleasing.
2Adaptability or versatility
If elastic inserts are integrated into the belt body, then longitudinal elasticity is improved, but construction complexity deteriorates
Solution Approach 1:
The elastic attachment is constructed as a separate modular unit with distinct components: outer body, inner body, housing, and elastic means. This segmentation allows for independent manufacturing and assembly, simplifying the overall construction process compared to integrating elasticity directly into the belt body.
Solution Approach 2:
The inner body is nested within the outer body, and the elastic means is housed within a housing on the inner body. This nested structure consolidates multiple components into a compact assembly that can be easily attached to the belt as a single unit, reducing construction complexity.
3Adaptability or versatility
If elastic inserts are integrated into the belt body, then longitudinal elasticity is improved, but durability deteriorates
Solution Approach 1:
By separating the elastic function into an independent attachment, the elastic means is protected within its own housing structure. This segmentation isolates the elastic component from direct exposure to wear and tear on the belt body, potentially extending its functional life.
Solution Approach 2:
The elastic means is housed within a protective housing on the inner body, which cushions and protects the elastic component from external damage and wear. This protective structure is built in advance to prevent premature failure of the elastic function.

AI summary
An elastic attachment (1) for a belt according to the present invention comprises an outer body (2), an inner body (3) slidingly arranged in an inner compartment (21) of the outer body (2), and elastic means (4) that allow the inner body (3) to return to the inner compartment (21). Advantageously, an elastic attachment thus constructed provides longitudinal elasticity to the belt to which it is applied without compromising its aesthetic appearance.
