Oven Front Panel Channel Assembly Without Welding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for assembling the front panel onto the oven body are time-consuming and costly due to the need for welding, and there is a need for a solution that facilitates stable assembly without welding.
Innovation Solution
The oven design incorporates a flange with a front opening and a front panel that is fixed by bending inward to form a bracket, using a connection piece with upper and lower channels to securely attach the panel to the flange, eliminating the need for welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a bracket is welded to the front panel to connect it to the flange, then the connection strength is improved, but the production time increases and production costs increase
Solution Approach 1:
A connection piece is introduced as an intermediary component between the front panel and the flange. This connection piece has an upper channel that receives the first flap and a lower channel that receives the flange wall, enabling welding-free assembly while maintaining connection strength. The intermediary component facilitates stable assembly without requiring welding operations.
Solution Approach 2:
The connection system is divided into separate components: the front panel with its integrated bracket, the flange, and a separate connection piece. This segmentation allows each component to be manufactured independently and assembled without welding, reducing production time and costs while maintaining structural integrity through the channel-based connection mechanism.
2Strength
If a bracket is welded to the front panel to connect it to the flange, then the connection strength is improved, but the production costs increase
Solution Approach 1:
The connection piece serves as a mediator that eliminates the need for welding operations. By providing pre-formed upper and lower channels that accommodate the bracket and flange respectively, it enables cost-effective assembly through simple insertion and fixation operations, reducing production costs while maintaining connection strength.
Solution Approach 2:
The welding process is replaced with a mechanical connection system using the connection piece with channels. This substitution eliminates the need for welding equipment, skilled welders, and post-weld treatments, thereby reducing production costs while achieving stable assembly through the mechanical interference fit of the channels.
3Stability of the object's composition
If welding is used to fix the front panel to the flange, then the assembly stability is improved, but the production complexity increases
Solution Approach 1:
The connection piece acts as a mediator that provides a pre-engineered connection interface with upper and lower channels. This intermediary component ensures assembly stability through its channel structure that accommodates the bracket and flange, while simplifying the overall production process by eliminating welding operations and reducing assembly complexity.

AI summary
An oven comprises a flange (30) with a front opening (36) which forms the front wall (345) of a body (10) wherein the foodstuff to be cooked are placed and which provides access into the body (10); a front panel (20) which is fixed by being rested to the flange (30) from a rear surface thereof (23); and at least one first flap (27) which is formed by bending the front panel (20) inwards the body (10) so as to form a bracket. Said oven comprises a connection piece (50) which is used for fixing the front panel (20) to the flange (30) and which has an upper channel (53) where said first flap (27) is accommodated; and which has a lower channel (52) where at least one wall (341, 342, 345) of said flange (30) is accommodated.
