Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional curtain hanging devices with coupling parts for wave curtains have exposed components, leading to unsightly appearances and entanglement issues, and are complicated to assemble.
Innovation Solution
A curtain hanging device featuring a tape-shaped coupling body with C-shaped engagement bodies that can be accommodated within a curtain rail, allowing for easy assembly and maintaining a neat appearance by preventing exposure and entanglement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a coupling part is used to integrate curtain hooks at constant intervals, then the curtain can maintain wave shape without becoming flat, but the coupling part becomes exposed from the curtain rail, resulting in poor appearance
Solution Approach 1:
The coupling part is designed with a nested structure where the coupling body is inserted into the coupling hole of the curtain rail, and the engagement protrusion fits into the engagement groove. This nesting arrangement allows the coupling part to be concealed within the curtain rail structure, eliminating exposure while maintaining the wave shape function.
2Device complexity
If a string or cord is used as the coupling part and accommodated in the inner space of the curtain rail, then the appearance may be improved, but the string or cord becomes entangled with the traveling runner, causing operational problems
Solution Approach 1:
The coupling part uses a rigid or semi-rigid rod-like structure instead of a flexible string or cord. This rod-shaped design maintains a fixed geometry that prevents entanglement with the traveling runner while still allowing the coupling part to be accommodated within the curtain rail's inner space, solving both appearance and reliability issues.
3Manufacturing precision
If a plate-shaped member is used as the coupling part to maintain constant intervals, then the curtain hooks can be regulated, but the assembly becomes complicated with multiple components including fitting protrusions, fitting holes, and locking pieces
Solution Approach 1:
The coupling part integrates multiple functions into a single unified structure. The rod-like body serves as both the spacing element and the engagement element, with the coupling hole and engagement groove built into the same component. This merging eliminates the need for separate fitting protrusions, locking pieces, and other auxiliary components, simplifying assembly while maintaining precise constant intervals.
