Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LED light schemes on charging piles lack the ability to achieve a wide range of light effects and fail to provide an ideal visual appearance due to the light source being visible from certain angles, resulting in a lackluster 'science and technology' feel.
Innovation Solution
A light assembly integrating a flexible light guide and a light transmitting frame, where the light source is embedded within the structure, allowing light to be transmitted along a defined path, creating a wide range of light effects while hiding the source, using materials like PC or PMMA for the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If LED light source is simply covered with light transmitting material, then the structure is simple and easy to manufacture, but the light effect range is limited and the light source is visible from certain angles
Solution Approach 1:
A light guide is introduced as an intermediary component between the LED light source and the light transmitting frame. The light guide receives light from the LED and transmits it along a defined path to the frame, enabling versatile light effects while keeping the LED hidden. This intermediary element resolves the contradiction by decoupling the simple LED structure from the complex light effect requirements.
Solution Approach 2:
The light guide extends the light transmission in a specific directional path (another dimension) rather than omnidirectional emission. By defining a specific extension path for light transmission through the frame, the system achieves targeted light effects while maintaining structural simplicity.
2Device complexity
If LED light source is simply covered with light transmitting material, then the structure is simple, but the light source is visible from certain angles and ideal light effect cannot be achieved
Solution Approach 1:
The light guide acts as a mediator that controls and directs light transmission. It receives light from the LED source and guides it along a defined path to the light transmitting frame, ensuring the light source remains hidden while achieving high-quality, controlled light effects. This resolves the contradiction by adding functional complexity only where needed for light control.
Solution Approach 2:
The light transmitting frame is designed with specific local properties - it has a defined extension path that allows light transmission in controlled directions while blocking other directions. This local quality control ensures the light source is hidden from certain angles while maintaining simple overall structure.
3Illumination intensity
If light source is hidden inside the light assembly, then good hiding effect is achieved, but the light transmission path must be precisely defined
Solution Approach 1:
The light guide is pre-formed with its extension path defined before assembly. The frame is designed with the light transmission path预先 established, so that during assembly, the light guide simply needs to be positioned within the frame along the pre-defined path. This preliminary preparation reduces the precision requirements during final assembly while ensuring good hiding effect.
