Vehicle Blind Coupling With Releasable Guide Strip Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blind assemblies for vehicles face difficulties in assembly and disassembly due to the secure fastening of pull cables to cross-roads, making them cumbersome during construction and repair.
Innovation Solution
A blind assembly with a releasable positive engagement mechanism between guide strips and an entraining element, allowing for easy assembly and disassembly, where the guide strips engage with a blind coupling via a groove and projection system, and are guided within a common channel to maintain engagement without disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pull cable is firmly fastened via an entraining element to a cross-rod at the end of the blind web, then the blind assembly achieves secure connection and reliable operation, but the assembly and disassembly processes become difficult and cumbersome
Solution Approach 1:
The blind assembly is divided into separable modules: the guide strip with entraining element can be detached from the blind coupling. This segmentation allows the blind to be easily assembled and disassembled while maintaining secure connection during operation, as the modular design enables simple attachment and detachment points without compromising operational reliability
Solution Approach 2:
The connection system transitions from a static permanent fastening to a dynamic reversible connection. The releasable positive engagement mechanism allows the blind to switch between a locked state during operation (ensuring reliability) and an unlocked state during assembly/disassembly (improving ease of manufacture), making the connection adaptable to different operational phases

AI summary
The invention relates to a blind assembly comprising a blind web (11) which is provided with one respective flexible, flat guide strip (10) along both lateral edge areas. Said guide strip (10) is guided inside a guide along the direction of extension of the blind in order to stretch the blind web. The base of the guide strip (10) is guided parallel to adjacent areas of the blind web. The inventive blind assembly further comprises at least one blind coupling with which at least one of the guide strips engages in a removable, positive manner via an entraining element (12) and via which the guide strip can be extended along with the blind web.
