Heating Cooking Apparatus Lid Alignment Using Rotatable Slide Rail
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heating cooking apparatuses face challenges in maintaining accurate parallelism between the plate portion and the lid portion when the lid portion covers the opening, leading to potential misalignment and inefficiencies.
Innovation Solution
The apparatus incorporates a slide rail, a slide plate, a rotation shaft portion, and a holding portion to ensure the lid portion can be freely rotated and aligned with the plate portion, maintaining parallelism by using a drive rail that rotates as a axis, allowing the lid to accurately cover the opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lid portion is moved to cover the opening, then the opening is closed, but parallelism between the plate portion and the lid portion cannot be accurately maintained
Solution Approach 1:
A guide rail is introduced as an intermediary component between the lid portion and the heating cooking chamber. The guide rail extends in the opening closing direction and includes a guide surface that contacts the lid portion, guiding its movement. This mediator ensures the lid portion maintains accurate parallelism with the plate portion throughout the closing motion, resolving the alignment accuracy issue.
Solution Approach 2:
The lid portion is designed to rotate about a rotation axis during the closing motion, rather than moving in a fixed rigid path. This dynamic movement allows the lid to adapt its orientation while closing, maintaining parallelism with the plate portion. The rotation mechanism enables the lid to dynamically adjust its position to achieve accurate alignment.
2Reliability
If the lid portion is held at a predetermined gap from the plate portion, then contact is avoided, but accurate parallelism maintenance becomes difficult
Solution Approach 1:
The guide rail serves as a mediator that physically constrains the lid portion's movement path. By contacting the lid portion through its guide surface, the guide rail ensures the lid maintains the predetermined gap from the plate portion while moving. This intermediary structure makes gap control automatic and reliable, eliminating the need for manual adjustment.
Solution Approach 2:
The guide rail is pre-configured with a specific geometry that inherently maintains the predetermined gap between the lid portion and the plate portion. The guide surface is designed in advance to enforce the correct spacing, so the gap control is built into the structure rather than requiring active control during operation.

AI summary
A heating cooking apparatus includes a heating cooking chamber, a slide rail, a slide plate, a lid portion, a rotation shaft portion, and a holding portion. The heating cooking chamber includes a plate portion disposed at the outer periphery of an opening. The slide rail extends along a first predetermined direction. The slide plate moves along the slide rail. The lid portion is attached to the slide plate and opens and closes the opening. The rotation shaft portion rotates the slide rail using a second predetermined direction orthogonal to the first predetermined direction as a rotation axis. The holding portion holds the slide rail to be freely rotatable with respect to the heating cooking chamber.
