Pivotable Locking Bar Fastening for Motor Vehicle Exhaust
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for motor vehicles and machines are not simple to operate and maintain, as they lack a reliable mechanism for easy mounting and removal of components, such as exhaust systems, which complicates maintenance processes.
Innovation Solution
A fastening device equipped with a bearing block, an anchor bracket, and a locking device that includes a pivotable locking bar and adjustable securing means, allowing for easy hooking and unhooking of components, ensuring reliable locking and simplified handling during mounting and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fastening device is designed to be simple to operate for mounting and removal, then ease of operation is improved, but reliability of the locking state may be compromised
Solution Approach 1:
The fastening device is segmented into distinct functional components: an anchor bracket with anchor hook for easy attachment, a locking bar for securing, and a securing means for maintaining the locked state. This segmentation allows simple hooking and unhooking operations while ensuring reliable locking through the separate locking mechanism.
Solution Approach 2:
The locking bar is designed to be pivotable between locked and unlocked positions, and the securing means is adjustable between securing and releasing states. This dynamic design enables easy operation for mounting and removal while maintaining high reliability when locked, as the system transitions between states rather than being statically fixed.
2Reliability
If a fastening device uses a secure locking mechanism, then reliability is improved, but device complexity increases
Solution Approach 1:
The securing means is designed to automatically secure the locking bar in the locked position once the anchor hook is attached to the stay bolt. The system self-secures through the interaction of its components, eliminating the need for additional complex securing mechanisms or multiple fastening steps, thus maintaining reliability while minimizing complexity.
3Ease of operation
If a fastening device allows easy detachment for maintenance, then ease of operation is improved, but strength of connection may be reduced
Solution Approach 1:
The locking bar is designed to extend behind the stay bolt in the locked position, creating a preliminary secure connection that prevents accidental detachment. This preliminary action ensures strong connection during normal operation while allowing intentional easy detachment when needed for maintenance by simply pivoting the locking bar to the unlocked position.
