Swing Oven Door Closure with Inverted Hook Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure systems for swing oven doors are complex and have protruding elements that compromise safety and design, making them difficult to clean and aesthetically unpleasing.
Innovation Solution
The closure system integrates the hook seat element into the door frame, with the hook element positioned at the oven frame, ensuring a compact structure and automatic vertical centring during closure, and using the same material as the door frame for a seamless design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hook element is assembled at the oven door, then the closure system can function, but protruding elements disturb the user and impair security
Solution Approach 1:
The patent inverts the conventional arrangement by placing the hook element at the oven frame and the hook seat element at the oven door. This inversion eliminates protruding elements from the oven door surface, as the hook seat element is recessed into the door, while maintaining the closure function through the complementary positioning at the frame.
Solution Approach 2:
The hook seat element is nested into a recess of the oven door, with its cross section matching the door frame shape. This nesting approach allows the closure mechanism to be integrated within the door structure rather than protruding from it, eliminating safety hazards while preserving functionality.
2Reliability
If the latch housing is arranged at the vertical side wall of the oven door, then the closure system can operate, but it causes a jagged structure of the oven door
Solution Approach 1:
The patent merges the hook seat element with the oven door structure by positioning it within a recess and giving it the same cross-sectional shape as the door frame. This merging creates a seamless, integrated appearance without jagged edges, while the closure operation remains functional through the coordinated movement with the hook element at the frame.
3Ease of manufacture
If the hook seat element has a different shape from the door frame, then it can be easily manufactured, but it does not form an integrated part of the door frame
Solution Approach 1:
The patent applies local quality by giving the hook seat element a cross-sectional shape that matches the door frame at its specific location. This localized shape adaptation allows the element to integrate seamlessly with the door frame's geometry while still being manufacturable using standard molding or fabrication processes for the overall component.
