Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mounting structure for planar-light-emitting panels requires a base portion on the back surface of interior members, which increases installation costs and complexity, and makes panel replacement risky due to the need for precise force application to avoid damage.
Innovation Solution
A lighting system with a detachable planar light source that includes a translucent plate to protect the light-emitting panel and allows output adjustment by pressing the light-emitting surface, eliminating the need for a base portion and simplifying switch operations, using a duct rail for power supply and mounting, enabling easy installation and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a base portion is provided on the back surface of interior members for mounting the planar light source, then the mounting structure is stable and reliable, but the installation cost and complexity increase
Solution Approach 1:
The patent removes the base portion from the mounting structure, extracting the unnecessary component that caused complexity. The planar light source is directly mounted to the interior member surface using a simplified fixing mechanism, eliminating the need for a separate base portion while maintaining mounting reliability.
Solution Approach 2:
The mounting structure is segmented into separate functional components: a fixing portion that attaches to the interior member surface and a mounting portion that holds the planar light source. This segmentation allows the base portion to be eliminated while maintaining structural stability through distributed attachment points.
2Reliability
If a base portion is required for mounting the planar light source, then the mounting structure is stable, but the installation cost increases
Solution Approach 1:
The base portion is extracted from the mounting structure, eliminating the need for additional materials and manufacturing steps. The fixing portion directly attaches to the interior member surface, reducing material costs and simplifying the manufacturing process.
Solution Approach 2:
The fixing portion serves multiple functions: it provides structural support, enables mounting stability, and facilitates installation without requiring a separate base portion. This multi-functionality reduces the overall component count and installation cost.
3Reliability
If precise force application is needed during panel replacement, then the panel can be safely detached, but the replacement process becomes complex and risky
Solution Approach 1:
The fixing portion uses a dynamic fixing mechanism that allows easy attachment and detachment of the planar light source. The fixing strength can be adjusted by simple operational forces, eliminating the need for precise force application during replacement while maintaining panel safety.
Solution Approach 2:
The mechanical fixing system is replaced with a simpler attachment mechanism that does not require precise force control. The fixing portion uses operational forces that are naturally within human capability, making replacement easy and safe without complex mechanical systems.
4Illumination intensity
If the light-emitting panel is directly exposed, then the light output is maximized, but the panel is vulnerable to damage from pressing operations
Solution Approach 1:
A protective plate made of transparent material is introduced as a composite layer between the user's pressing action and the light-emitting panel. This protective layer has sufficient mechanical strength to withstand pressing operations while maintaining optical transparency to preserve light output.
Solution Approach 2:
The protective plate is installed beforehand to cushion and distribute pressing forces before they reach the light-emitting panel. This pre-installed protective layer prevents direct contact between the pressing force and the fragile panel, ensuring durability while maintaining light transmission.

AI summary
An object of the present invention is to provide a lighting system and a planar light source that allows an easy switch operation for adjusting an output of planar light. The planar light source emits planar light by power supplied from a mounting member. The planar light source includes an engaging part, a planar-light-emitting panel having a light-emitting surface, and a connecting unit disposed between the engaging part and the planar-light-emitting panel. The engaging part forms a portion of a power supply path for supplying power from the mounting member to the planar-light-emitting panel. The planar-light-emitting panel includes a planar-light-emitting tile and a translucent plate, where one main surface of the planar-light-emitting tile includes a light-emitting region. The planar-light-emitting panel emits, in a lighting state, the planar light from the light-emitting region of the planar-light-emitting tile through the translucent plate. An output of the planar light from the planar light source is adjusted by pressing the light-emitting surface.
