Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a light emitting mechanism with inclined plane and reflector is added to the front panel assembly, then the visual sense of layering and stereoscopic effect is improved, but the device complexity increases
Solution Approach 1:
The light guide body is divided into multiple sections including an inclined plane section and a light emitting section. The front panel assembly is segmented into the front panel body, light guide body, and light emitting mechanism. This segmentation allows each component to perform its specific function while maintaining overall simplicity and reducing manufacturing complexity.
Solution Approach 2:
The inclined plane is designed with a specific inclination angle (α) relative to the horizontal direction, introducing a dimensional change that creates the stereoscopic effect. The light emitting mechanism utilizes three-dimensional spatial arrangement of the light source, light guide body, and reflector to achieve the desired visual effect without excessive structural complexity.
2Illumination intensity
If the light source is placed inside the front panel body with light guide body, then the light emission effect is improved, but the ease of installation and replacement of light source deteriorates
Solution Approach 1:
The light source is extracted from a fixed embedded position and placed on the light guide body which can be independently removed. This allows the light source to be easily taken out and replaced by simply removing the light guide body from the front panel assembly, without requiring disassembly of the entire panel structure.
Solution Approach 2:
The light guide body is designed with dynamic positioning capability, allowing it to be easily installed and removed from the front panel body. The light source on the light guide body can be dynamically accessed for replacement while maintaining the light emission effect when properly positioned.
3Stability of the object's composition
If a supporting frame with inclined structure is added to support the light guide body, then the position stability is improved, but the device complexity increases
Solution Approach 1:
The supporting frame is merged with the front panel body as an integrated structure. The inclined structure of the supporting frame combines both the support function and the inclination angle requirement in a single structural element, eliminating the need for separate support components and reducing overall device complexity.
Solution Approach 2:
The supporting frame serves multiple functions: it supports the light guide body, provides the required inclination angle (α), and integrates with the front panel body structure. This multi-functionality reduces the number of separate components needed while maintaining position stability.
