Oven Door Bumper Heat Faces for Passive Lateral Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current domestic appliances, such as ovens, face challenges with heat dissipation, as traditional dampening and heat dissipation methods like blowers and heat-resistant materials are costly, noisy, and inefficient, particularly in dissipating heat from sensitive areas unreachable by air flow.
Innovation Solution
A resilient bumper is positioned between the cabinet and door of the oven, featuring linear heat faces to guide heated air laterally, reducing heat accumulation in sensitive areas and enhancing heat dissipation without the need for additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional dampening means are used, then door closure dampening is provided, but heat dissipation is insufficient and heat accumulates in sensitive areas
Solution Approach 1:
The bumper is designed to perform multiple functions simultaneously: it provides door closure dampening through its resilient material properties while also serving as a heat dissipation component through its geometric configuration with heat faces that guide heated air laterally. This multi-functionality eliminates the need for separate heat dissipation devices.
Solution Approach 2:
The invention merges the dampening function and heat dissipation function into a single integrated component (the bumper). The bumper combines the shock-absorbing characteristics of resilient materials with geometric features (heat faces) that redirect heat flow, thereby combining two previously separate functions into one element.
2Temperature
If blowers are used for heat dissipation, then heat is dissipated from the cavity, but the blower motors are loud, expensive, and occupy large spaces
Solution Approach 1:
The invention extracts the heat dissipation function from the complex blower motor system and implements it through a passive geometric feature (the bumper with heat faces). This removes the need for active mechanical components like motors, belts, and housings, thereby eliminating noise, cost, and space requirements associated with traditional blower systems.
Solution Approach 2:
The bumper utilizes the natural flow of heated air and its own geometric configuration to achieve heat dissipation without requiring external power sources or control systems. The heat faces passively guide heated air laterally along the bumper, allowing the component to serve its heat dissipation function autonomously.
3Object-affected harmful factors
If heat resistant materials are used, then heat damage is prevented, but the materials are very costly and require reapplication
Solution Approach 1:
The bumper acts as an intermediary component that redirects heat flow away from sensitive areas rather than relying on expensive heat-resistant materials to withstand high temperatures. The heat faces guide heated air laterally, preventing direct contact with sensitive components and reducing the need for costly protective materials.
