Adjustable Blind Fitting Telescopic Core Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blind system installations face challenges due to variations in the distance between supporting structures, requiring reinstallation or replacement of components, which complicates the installation process and affects the quality of the finishing on the installation surface.
Innovation Solution
A length adjustable fitting for blind systems, comprising a housing, a drive member, a core member, and biasing means, which allows selective adjustment of the drive member relative to the housing, enabling the core member to move along an axis to different positions, resisting movement and minimizing accidental retraction, thus accommodating variations in supporting structure spacing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If supporting structures are installed in fixed positions, then the installation structure is simple, but the fitting cannot accommodate variations in distance between supporting structures
Solution Approach 1:
The fitting incorporates a telescopic mechanism that allows the core member to extend and retract along the longitudinal axis, transforming a static structure into a dynamic one. This enables the fitting to adapt to varying distances between supporting structures while maintaining a relatively simple overall design.
Solution Approach 2:
The core member is nested within the drive member, with the core member able to slide in and out of the drive member's hollow body. This nested arrangement allows for length adjustment without requiring completely separate components, thereby managing complexity while providing adaptability.
2Ease of operation
If the tube length is fixed, then the manufacturing is simpler, but reinstallation is required when distance variations occur
Solution Approach 1:
The telescopic mechanism allows the fitting to be adjusted in situ to match the actual distance between supporting structures, eliminating the need for reinstallation. The operator can simply extend or retract the core member to achieve the correct length, significantly reducing installation time and effort.
3Reliability
If the supporting structures are repositioned, then the fitting engagement is correct, but the finishing quality on the installation surface is affected
Solution Approach 1:
By allowing the fitting length to be dynamically adjusted, the original positions of the supporting structures can be maintained, preserving the quality of the installation surface finishing. The core member is extended or retracted to achieve proper engagement without moving the supporting structures.
4Reliability
If a tube of new length is ordered, then the correct engagement is achieved, but the complication and time needed for installation increases
Solution Approach 1:
The telescopic mechanism provides continuous length adjustment capability, allowing the fitting to be configured for the specific distance between supporting structures during installation. This eliminates the need to order custom-length tubes, significantly improving installation efficiency while ensuring correct engagement.
Solution Approach 2:
A single universal fitting design with telescopic capability can accommodate a range of distances between supporting structures, replacing the need for multiple fixed-length tube variants. This multi-functional approach streamlines inventory management and accelerates the installation process.
