Press-Fit Griddle Insulation Retainer for Stable Range Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing griddle insulation retainers are difficult to install and remove due to screw-based attachment systems, leading to instability and potential sagging of the griddle during range installation and maintenance.
Innovation Solution
A press-fit mounting arrangement using tabs and bridge lances on the griddle insulation retainer and housing allows for tool-free installation and removal, enhancing stability and ease of access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw-based attachment system is used for griddle insulation retainer, then the retainer can be securely mounted, but the installation and removal become difficult and time-consuming
Solution Approach 1:
The mounting system is segmented into discrete tab components on the retainer and corresponding receiver components on the housing. Each tab fits into a corresponding receiver, creating modular, easily engageable mounting points that eliminate the need for screws while maintaining secure attachment.
Solution Approach 2:
The screw-based mechanical fastening system is replaced with a press-fit tab and receiver system. This substitution eliminates threaded fasteners, alignment requirements, and tool needs while providing sufficient mounting security through friction-fit engagement of the tab components into the receiver openings.
2Reliability
If multiple screws are used to secure the griddle insulation retainer, then the mounting is secure, but the structural integrity of the griddle may be compromised causing sagging
Solution Approach 1:
The mounting system uses multiple distributed tab-receiver pairs positioned at strategic locations across the retainer. This local distribution of mounting points provides secure attachment without concentrating stress at single screw locations, thereby maintaining griddle structural integrity and preventing sagging.
Solution Approach 2:
The tab and receiver components are pre-formed during manufacturing with precise dimensions and tolerances. This preliminary preparation ensures that when assembled, the tabs fit snugly into the receivers without requiring additional fastening actions, thereby securing the retainer while maintaining griddle stability.
3Reliability
If screw openings are maintained in registry for attachment, then secure mounting is achieved, but the alignment requirement makes installation complex
Solution Approach 1:
Instead of requiring precise alignment of screw openings through the griddle structure, the tab components extend from the retainer and fit into receivers that are accessible from the rear side. This inverted approach eliminates the need for complex alignment through multiple layers, as the tabs can be inserted into receivers without requiring registry of openings through the entire griddle assembly.
