Drawer Microwave Side Panel Rigidity via Slide Rail Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drawer type microwave ovens face challenges in preventing microwave leakage during the jerk microwave leakage test due to the elastic deformation of side panels under torsional forces, which complicates design and increases costs, and restricts handle design, limiting their adoption in interior-designed kitchens.
Innovation Solution
The solution involves reinforcing the side panels of the heating chamber by aligning the fixed-side moving members of the slide mechanism with shock absorbing members at the rear sides of the side panels, reducing the likelihood of elastic deformation and maintaining rigidity without additional reinforcement members, thus preventing microwave leakage during the jerk test.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the side panels of the heating chamber are made thinner to reduce manufacturing costs, then the manufacturing cost decreases, but the side panels become more susceptible to elastic deformation under torsional forces during the jerk microwave leakage test
Solution Approach 1:
The slide mechanism's fixed-side moving members are strategically positioned to align with shock absorbing members at specific locations on the side panels. This creates localized reinforcement zones where the slide mechanism structurally supports the side panels, providing differential stiffness - thinner panels in non-critical areas and reinforced panels at critical shock absorption points
Solution Approach 2:
The invention merges the shock absorption function with the slide mechanism structure. The fixed-side moving members of the slide mechanism serve dual purposes: guiding drawer movement and providing structural reinforcement to prevent elastic deformation of side panels during torsional stress events
2Strength
If additional reinforcement members are added to the side panels to prevent elastic deformation, then the structural integrity improves, but the device complexity and manufacturing cost increase
Solution Approach 1:
The slide mechanism is designed so that its fixed-side moving members serve multiple functions: they guide the drawer body during normal operation and simultaneously act as reinforcement members to prevent elastic deformation of the side panels during jerk tests. This multi-functionality eliminates the need for separate reinforcement components
Solution Approach 2:
The reinforcement function is merged into the existing slide mechanism structure rather than being implemented as separate reinforcement members. The fixed-side moving members of the slide mechanism provide both guidance and structural support, reducing overall device complexity
3Shape
If the latches are disposed at deep areas within the cooking device body to maintain visual appearance, then the aesthetic quality improves, but the reliability of microwave leakage prevention decreases during the jerk test
Solution Approach 1:
The slide mechanism with aligned fixed-side moving members provides preliminary structural support to the side panels before torsional forces are applied during the jerk test. This pre-reinforcement prevents elastic deformation that would otherwise occur when the door is twisted, ensuring latches remain properly engaged even when disposed at deep locations for aesthetic purposes

Function Achieved in This Case
This approach allows for a microwave leakage-free drawer type microwave oven that passes the jerk microwave leakage test while reducing the thickness of components and maintaining structural integrity, without increasing manufacturing costs or handle design limitations.

AI summary
The invention provides a drawer type cooking device, wherein the mounting positions of roller-shaped shock absorbing members 10b and 10b attached to a drawer body 2 are either aligned with portions of the side walls 3b and 3b of the heating chamber 3 where fixing angles 8 of the slide rails 7 are attached and thus having enhanced rigidity, or arranged close to a bottom wall 3c of the heating chamber 3, so that when a biased operation force is applied to the door, the generation of a gap between a front side panel of the cooking device body 1 and the inner side of the door is suppressed, and the occurrence of a microwave leakage through the gap caused by not stopping the generation of microwave until the operation of a latch is thereby prevented in advance.
