Quick-Action Fastener Stop for Oven Guide Rail Latch Overbending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick-action fastening elements for guide rails on grid-like side parts in ovens often suffer from overbending, leading to loss of functionality and risk of injury due to uncontrolled pivoting, and fail to ensure secure reassembly.
Innovation Solution
A quick-action fastening element with a stop to limit the pivoting path of the latching element, preventing overbending and incorporating a projection for secure engagement behind the rod, along with a handle section for easy actuation and assembly, minimizes the risk of injury and ensures safe handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the latching element is made pivotable for easy assembly and disassembly, then ease of operation is improved, but the risk of overbending and loss of functionality increases
Solution Approach 1:
A stop is provided on the quick-action fastening element that limits the pivoting path of the latching element before it can be overbent. This preliminary constraint prevents excessive deformation by defining the maximum allowable pivot angle, thereby maintaining the elastic range while enabling easy assembly and disassembly operations.
2Ease of operation
If the latching element is allowed to pivot freely for disassembly, then ease of operation is improved, but the risk of injury from uncontrolled pivoting increases
Solution Approach 1:
The stop is positioned to limit the pivoting path of the latching element in advance, preventing uncontrolled movement beyond a safe angle. This preliminary constraint ensures that even during rapid disassembly operations, the latching element cannot pivot far enough to cause injury to the user.
3Reliability
If the latching element is made resilient for secure engagement, then reliability is improved, but the susceptibility to permanent bending and loss of function increases
Solution Approach 1:
The stop provides a preliminary mechanical constraint that prevents the latching element from being bent beyond its elastic limit. By limiting the pivoting path before excessive force can be applied, the stop protects the resilient material from permanent deformation while maintaining its ability to provide secure engagement during normal operation.
