Cover Attachment for Articulated Vehicle Bellows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing articulated vehicle connections with visible screw connections are vulnerable to unauthorized tampering, and current cover designs require damaging the bellows to replace the cover, necessitating disassembly of the bellows.
Innovation Solution
A connecting device allows the cover to be independently connected and detached from the connection frame using a keder connection, preventing damage to the bellows and enabling replacement without disassembly, while providing sealing lips to prevent moisture ingress and enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cover is sewn to the end flap of the bellows and held in place by a clamping groove, then the cover can prevent unauthorized access to the screw connection, but the bellows must be disassembled to replace the cover and the end flap is damaged
Solution Approach 1:
The invention separates the cover from the bellows assembly by providing it with an independent connecting device that attaches directly to the connecting frame. This segmentation allows the cover to be replaced independently without disassembling the bellows or damaging the end flap, while still maintaining security coverage over the screw connection.
2Stability of the object's composition
If the cover is held in place on the connecting frame by crimping the end flap, then the cover remains secure, but the bellows cannot be reassembled after cover replacement
Solution Approach 1:
The cover is segmented from the bellows structure and equipped with its own connecting device that attaches to the connecting frame. This independent attachment mechanism ensures stable coverage while preserving the bellows' integrity and reassembly capability.
Solution Approach 2:
The connecting device acts as an intermediary between the cover and the connecting frame, providing a secure attachment mechanism that does not involve the bellows' end flap. This intermediary structure enables stable cover attachment while leaving the bellows assembly intact and reversible.
3Device complexity
If the screw connection of the connecting frame is left visible, then the assembly is simple, but unauthorized persons can loosen the screw connection
Solution Approach 1:
The cover serves as an intermediary protective element that covers the vulnerable screw connection of the connecting frame. By placing the cover over the screw connection area, the invention protects against tampering while maintaining the simplicity of the underlying assembly structure.
