Slider Closing Member Conceals Fixing Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliders for slide fasteners have exposed fixing structures for the closing member, making the appearance of the pull tab connecting portion intricate and increasing manufacturing costs, as the closing member is fixed to both the slider body and the pull tab connecting post.
Innovation Solution
A slider design where the closing member is fixed to the slider body using an engaging portion and a fixing portion that are covered by the closing member's outside portion, allowing for a unified appearance and eliminating the need for complex shapes and additional manufacturing steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the closing member is fixed to both the slider body and the pull tab connecting post, then the closing member is securely attached, but the fixing structure is exposed to the outside and the appearance becomes intricate
Solution Approach 1:
The fixing structure is nested within the closing member itself. The closing member includes an engaging portion that engages with the slider body and a body portion that covers the engaging portion, effectively hiding the fixing mechanism from external view while maintaining secure attachment functionality.
Solution Approach 2:
The closing member acts as a shell that encapsulates the fixing structure. By designing the closing member to cover the engaging portion, the invention uses the shell-like structure of the closing member itself to conceal the fixing mechanism, achieving aesthetic unity while maintaining functionality.
2Reliability
If the closing member is fixed to both the slider body and the pull tab connecting post, then the closing member is securely attached, but the manufacturing cost increases due to complex shapes and additional steps
Solution Approach 1:
The fixing function and the aesthetic cover function are merged into a single component - the closing member. By integrating the engaging portion and the body portion into one piece, the invention eliminates the need for separate fixing components and reduces manufacturing steps while maintaining secure attachment.
Solution Approach 2:
The closing member serves multiple functions: it provides the aesthetic appearance, covers the engaging portion, and maintains secure attachment through the engaging portion. This multi-functionality reduces the total number of components needed and simplifies manufacturing processes.
3Ease of operation
If the fixing structure is exposed, then the closing member can be easily attached and detached, but the overall appearance of the pull tab connecting portion cannot be unified
Solution Approach 1:
The engaging portion is nested within the closing member's body portion. This nesting arrangement allows the fixing structure to remain accessible for operation while being visually concealed from the outside, achieving both ease of operation and appearance unity.
Solution Approach 2:
The closing member has different local qualities: the body portion provides aesthetic coverage while the engaging portion maintains functional accessibility. This local differentiation allows the structure to simultaneously achieve unified appearance and ease of operation.

AI summary
A slider having a tab connecting part provided on a surface of the upper blade of the slider body. The tab connecting part has a cantilevered tab connecting post, with one end portion fixed to the surface of the upper blade at one end and the other end portion is separated from the surface at the other end in the longitudinal direction; and a closing member attached between the other end portion of the tab connecting post and the surface of the upper blade. The slider body includes a fixing portion provided on the surface of the upper blade. The closing member includes an outside portion defining a surface facing opposite to the one end portion, where the closing member is attached to the surface of the upper blade, and an engaging portion, provided on the one end portion-side of the outside portion and engageable with the fixing portion.
