Cooktop Control Panel Bracket for Heat and Liquid Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cooking appliances face issues with heat conduction from the top plate to the control panel, causing user burns and errors due to liquid permeation between the control panel and top plate, which affects the manipulation units and gas valves.
Innovation Solution
A bracket system is introduced to detachably couple the control panel to the top plate, creating a gap for reduced heat transfer and a passage to guide liquids, with projections and inclined surfaces to enhance user accessibility and prevent liquid-induced errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the control panel is directly coupled to the top plate using multiple bolts, then the control panel is securely fixed, but the coupling process becomes difficult and maintenance requires unfastening multiple bolts
Solution Approach 1:
The coupling mechanism is divided into a bracket portion attached to the top plate and a control panel coupling portion. This segmentation allows the control panel to be coupled through a single bracket assembly rather than multiple individual bolts, simplifying the coupling process while maintaining secure fixation.
Solution Approach 2:
The bracket combines multiple coupling functions into a single integrated component. The bracket includes both the attachment portion for the top plate and the coupling portion for the control panel, merging what would otherwise require separate fastening operations into one unified coupling mechanism.
2Stability of the object's composition
If the top plate is disposed directly over the control panel for structural integration, then structural integration is achieved, but heat conduction from the top plate to the control panel causes user burns
Solution Approach 1:
The bracket serves as an intermediary component between the top plate and the control panel. It includes a heat insulating portion that mediates the thermal interaction, allowing structural integration while blocking heat conduction paths from the hot top plate to the control panel, thereby preventing user burns.
3Volume of moving object
If the control panel is positioned under the front portion of the top plate for compact design, then compact design is achieved, but liquid permeation between the control panel and top plate causes manipulation unit errors
Solution Approach 1:
The bracket acts as a protective intermediary between the control panel and the top plate. It includes a liquid blocking portion that prevents liquid permeation through the interface, thereby protecting the manipulation units from liquid-induced errors while maintaining the compact design with the control panel positioned under the top plate.
4Stability of the object's composition
If multiple bolts are used to secure both the top plate and control panel, then secure fixation is achieved, but maintenance of the control panel and manipulation units requires unfastening multiple bolts
Solution Approach 1:
The coupling system is segmented into a reusable bracket portion that remains attached to the top plate and a removable control panel coupling portion. This segmentation allows the control panel to be quickly detached for maintenance by removing only the coupling portion rather than unfastening multiple bolts, significantly easing repair operations.
