Appliance Control Panel Lip Lighting for Low-Light Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Household appliances, especially those in low-light areas, often have difficulty with control readability due to the lack of integral lighting, leading to improper operation and energy wastage.
Innovation Solution
A control device with a panel lip housing lighting devices positioned above the controls, allowing direct illumination and easy access for maintenance, using LEDs and a thermally conducting support system for efficient heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If integral lighting devices are installed in the appliance to illuminate the controls, then control readability in low-light conditions is improved, but the structure and components become complicated
Solution Approach 1:
The patent combines multiple lighting devices into a single integrated assembly mounted on the control panel. Instead of having separate lighting devices for each control, the invention merges them into one unified structure that illuminates multiple controls simultaneously, reducing overall complexity while maintaining illumination effectiveness
Solution Approach 2:
The lighting device assembly serves multiple functions: it provides illumination for multiple different controls (oven controls, burner controls, etc.), acts as a structural mounting element, and can be positioned to illuminate various areas of the control panel. This multi-functionality reduces the need for separate dedicated lighting devices for each control
2Illumination intensity
If each control has its own exclusive lighting device, then control illumination is improved, but the lighting devices become difficult to reach, repair or replace
Solution Approach 1:
By merging multiple lighting devices into a single accessible assembly mounted on the control panel, the invention makes the entire lighting system reachable from the front of the appliance. This allows easy access for repair or replacement without disassembling difficult-to-reach components, while still providing dedicated illumination for each control area
3Illumination intensity
If lighting devices are installed to illuminate controls directly, then control readability is improved, but the structure becomes complicated
Solution Approach 1:
The patent uses a reflective surface or diffuser as an intermediary between the lighting device and the controls. The lighting device illuminates this intermediary surface, which then reflects or diffuses the light onto the controls, providing effective illumination while simplifying the direct lighting structure and reducing the number of components needed
