Buckle Device Restricting Section Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buckle devices lack a mechanism to secure a space between the outer and inner side members of an extending and contracting member, which affects the stability and functionality of the buckle movement.
Innovation Solution
A buckle device with a restricting section that prevents relative displacement of the inner and outer side members in the direction where the space narrows, allowing for the securement of a space between them, and includes a moving member and a coupling mechanism to facilitate controlled movement and enhanced rigidity.

Engineering Contradiction Analysis
1Length of moving object
If the inner side member and outer side member are fitted together by fitting an outer face of the inner side member with an inner face of the outer side member, then the extending and contracting member can be moved, but no space can be provided between the outer side member and the inner side member
Solution Approach 1:
The fitting structure is segmented into multiple functional sections: a fitting section for connection, and a restricting section with restricting protrusions and restricting grooves that create and maintain space between members. This segmentation allows the space-securing function to be added without redesigning the entire fitting structure.
Solution Approach 2:
The restricting protrusions and restricting grooves act as intermediary elements between the inner side member and outer side member. These intermediaries prevent direct contact in certain directions, thereby securing space while still allowing the members to be fitted together and moved relative to each other.
2Stability of the object's composition
If the inner side member and outer side member are fitted together tightly, then structural stability is improved, but the space between them cannot be secured
Solution Approach 1:
The restricting section is provided locally at specific positions along the extending and contracting member, rather than uniformly throughout. This local provision of space-securing functionality maintains structural stability in most areas while creating necessary space in specific locations where the restricting protrusions and grooves are positioned.

AI summary
In a buckle device, displacement of a buckle cover in a width direction with respect to a buckle guide is restricted by restricting grooves of the buckle cover and restricting ribs of the buckle guide that enter the restricting grooves. This enables a space to be secured between a wall portion on one side in a width direction of the buckle cover and a wall portion on one side in a width direction of the buckle guide.
