LED Oven Light Holding Plate for Sealed Retrofit Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking appliances with conventional lighting technology face challenges in adapting to LED lighting due to temperature sensitivity and different installation requirements, leading to economic and sustainability issues with tool adaptation and redesign.
Innovation Solution
A holding plate with a fastening base and elastic sealing element is used to anchor the LED light source in the cooking chamber wall, allowing seamless transition from traditional to LED technology without modifying the muffle or light sources, using existing production tools and components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional lighting technology is used in cooking appliances with existing production tools, then manufacturing cost is reduced and production efficiency is maintained, but energy efficiency is poor and temperature control is insufficient for modern lighting requirements
Solution Approach 1:
A holding plate is introduced as an intermediary component between the existing opening in the cooking chamber wall and the LED light source. The holding plate adapts the conventional opening to accommodate the LED module with different installation requirements, enabling LED technology integration without modifying existing production tools or muffle components.
2Use of energy by moving object
If LED light sources are installed directly in existing openings, then energy efficiency is improved, but the temperature sensitivity of LED requires greater distance from cooking chamber which conflicts with existing opening positions
Solution Approach 1:
The holding plate serves as a mediator that bridges the gap between the fixed opening position in the cooking chamber wall and the LED light source that requires greater distance due to temperature sensitivity. It enables proper spacing while maintaining integration with existing appliance structure.
Solution Approach 2:
The lighting system is segmented into separate functional components: the holding plate mounted in the existing opening, the LED light source positioned at appropriate distance, and light guides that transmit illumination into the cooking chamber. This segmentation allows each component to be optimized independently.
3Reliability
If production tools are adapted or replaced for LED lighting, then lighting technology is updated, but manufacturing cost increases and production time is extended
Solution Approach 1:
The holding plate is designed as a universal adapter that can be integrated into existing production lines without requiring new specialized tools. It maintains compatibility with conventional manufacturing processes while enabling LED light source installation, thus preserving production efficiency during technology transition.
4Loss of energy
If the opening size in cooking chamber wall is reduced for LED light sources, then sealing is improved and heat loss is reduced, but installation flexibility is reduced and existing openings cannot be used
Solution Approach 1:
The holding plate creates a localized sealing structure at the opening position, concentrating the sealing function in a specific area rather than requiring the entire opening to be minimized. This allows the opening to maintain its original size for installation flexibility while achieving effective sealing through the plate's design.
