Solution Overview
Problem
Neon tube and LED lighting devices produce diffused light that is perceived as pale and aggressive, leading users to prefer alternative lighting sources like incandescent or halogen lamps, despite the energy efficiency and longevity of neon and LED lighting.
Innovation Solution
A lighting device featuring a plate with a neon tube or LED light source, a diffuser screen made of stretched flexible fabric, and a protective grid, where the diffuser screen is connected to the grid by magnetic means, providing a lampshade-like function to filter and soften the light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If neon tube or LED lighting is used, then power consumption is reduced and lamp longevity is increased, but the diffused light is perceived as pale and aggressive
Solution Approach 1:
A diffuser screen made of stretched flexible fabric is introduced as an intermediary element between the neon tube/LED light source and the users. This screen filters the raw light emitted by the energy-efficient lighting, transforming its perceptual quality from pale and aggressive to warm and pleasant, while allowing the energy-efficient lighting to continue operating
Solution Approach 2:
The diffuser screen modifies the color temperature and spectral composition of the light emitted by the neon tube or LED. By filtering certain wavelengths and diffusing others, the screen transforms the characteristic cool white light of energy-efficient lighting into a warmer, more pleasant illumination that resembles traditional lighting perceptions
2Object-affected harmful factors
If a diffuser screen is added to filter light, then light perception becomes more pleasant, but device complexity increases
Solution Approach 1:
The diffuser screen is constructed from a stretched flexible fabric that can be tensioned and secured to the protective grid without requiring complex mechanical assemblies. This flexible film approach simplifies the overall structure compared to rigid diffuser systems, reducing device complexity while maintaining effective light filtering
Solution Approach 2:
Magnetic connecting means are used to attach the diffuser screen to the protective grid, replacing traditional mechanical fastening systems such as screws, clips, or adhesives. This magnetic attachment method simplifies assembly and disassembly operations, reducing the complexity of the mounting mechanism
3Ease of operation
If magnetic connecting means are used to attach the diffuser screen, then ease of assembly is improved, but holding force may be insufficient for large screens
Solution Approach 1:
The protective grid and diffuser screen assembly is divided into multiple modular sections, each with its own magnetic connecting means. By segmenting the overall structure into smaller units, the magnetic holding force required for each individual connection is reduced, while the cumulative effect across multiple segments provides sufficient overall attachment strength for large screens
Solution Approach 2:
The magnetic connecting means utilize magnetic material with optimized magnetic properties and are positioned at multiple locations around the periphery of the diffuser screen. By changing the distribution and characteristics of the magnetic attachment points, the system achieves both easy assembly through simple magnetic attraction and sufficient holding force through distributed attachment
