Rotating Shade End Cap for Adjustable Vehicle Roller Length
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle roller shade assemblies face challenges in versatility and ease of installation due to fixed lengths and weight/cost issues, requiring a solution for adjustable end caps that can accommodate various vehicle models and interior configurations.
Innovation Solution
A rotating end cap design with a base and extension, connected via a rotating connector, allowing for two-position adjustment to reduce length and accommodate multiple vehicle lines, featuring a 45° angled surface and secure locking mechanism for easy installation and reduced manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-length roller design is used, then the manufacturing process is simple, but the shade assembly cannot accommodate varying vehicle interior dimensions
Solution Approach 1:
The end cap is designed with a rotating connector that allows it to pivot between a first position (extending the roller length) and a second position (reducing the roller length). This dynamic adjustment mechanism enables a single roller design to accommodate multiple vehicle interior dimensions, resolving the contradiction between adaptability and design complexity.
2Adaptability or versatility
If multiple roller length variations are manufactured, then versatility across vehicle lines is achieved, but manufacturing cost and design complexity increase
Solution Approach 1:
A single universal roller design incorporates a rotating end cap that can be adjusted to different positions, allowing the same roller to fit multiple vehicle lines. This eliminates the need to manufacture multiple roller variations, thereby reducing manufacturing costs while maintaining versatility.
Solution Approach 2:
The rotating end cap provides dynamic length adjustment, enabling one roller design to perform the function of multiple fixed-length rollers. This dynamic capability allows a single manufacturing process to serve multiple vehicle applications, reducing overall manufacturing complexity and cost.
3Ease of operation
If spring-loaded end caps are used, then self-centering action and ease of installation are achieved, but weight and cost increase
Solution Approach 1:
The rotating end cap is designed to be manually operable without requiring spring mechanisms. The user can directly rotate the end cap between positions, eliminating the need for springs while maintaining ease of installation and operation. This reduces both weight and cost compared to spring-loaded designs.

AI summary
An end cap for use in a shade assembly for use in a vehicle wherein the end cap is a rotating end cap. The end cap is capable of rotating and twisting and includes a base and a rotating connector partially arranged within an end of the base. The rotating end cap also includes an extension with the rotating connector partially arranged within an end of the extension. The rotating end cap will allow for the end cap to effectively reduce its length by rotating the extension with relation to the base from a generally parallel position to one having an orthogonal position between the extension and base.
