Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small rooms, such as elevators, often cause claustrophobia due to perceived lack of space, and existing solutions like mirrors provide limited optical enlargement and increased costs with complex textile fabric lighting devices.
Innovation Solution
A lighting device with a strip-like design that illuminates a structured aluminum foil reflector surface, simulating dome-like or pointed-roof designs to enhance perceived room height and depth, using LEDs on frame profiles for easy assembly and low-cost production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If mirrors are used to enlarge the perceived room space, then the optical enlargement effect is achieved, but the cost increases and the effect is limited
Solution Approach 1:
The patent uses changes in light color temperature (from warm to cool white) to create different visual perceptions of space. The LED module transitions between color temperatures to simulate different lighting conditions that affect perceived room size, providing an optical enlargement effect without using mirrors or complex structures.
Solution Approach 2:
The patent introduces temporal dimension by dynamically changing light color temperature over time. This creates a dynamic lighting experience that simulates different times of day or weather conditions, enhancing the perceived space through temporal variation rather than static mirror reflections.
2Illumination intensity
If textile fabrics with light sources are used to create lighting effects, then optical effects are achieved, but the technical requirements and costs are high
Solution Approach 1:
The patent extracts the light source from complex textile fabric structures and places it in a simple LED module mounted on the rear wall. This separates the illumination function from the complex optical structures, achieving lighting effects with minimal technical complexity while maintaining high illumination quality.
Solution Approach 2:
The patent replaces mechanical/optical systems (textile fabrics with embedded light sources) with an electrical system (LED module). This substitution simplifies the device by using electrically controllable LEDs instead of mechanically complex fabric-based lighting systems.
3Area of stationary object
If complex optical structures are used to simulate room enlargement, then the perceived space increases, but the device height and complexity increase
Solution Approach 1:
The patent uses color temperature transitions to create depth perception. By shifting from warm to cool white light, the system simulates different lighting conditions that enhance perceived room depth without requiring physically tall structures or complex optical elements.
