Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual fixing of light sources to the frame is used, then the light sources can be securely attached, but the assembly process becomes complicated and time-consuming
Solution Approach 1:
The frame is divided into a bottom plate and side plates that are separable, allowing the light sources to be fixed to the bottom plate independently. This segmentation enables automated or simplified assembly processes while maintaining secure attachment of multiple light sources.
Solution Approach 2:
A fixing member is introduced as an intermediary component between the light sources and the frame. This fixing member simplifies the attachment process by providing a standardized interface, reducing assembly time while ensuring reliable fixation of the light sources.

3Area of stationary object
If numerous light sources are required for large-sized displays, then the display area can be covered, but the assembly operation becomes more complicated and time-consuming
Solution Approach 1:
The frame is divided into a bottom plate and side plates that are separable, allowing the light sources to be fixed to the bottom plate independently. This segmentation enables automated or simplified assembly processes while maintaining secure attachment of multiple light sources.
Solution Approach 2:
The fixing member serves as a universal component that can be used to attach multiple light sources to the frame in a standardized manner. This multi-functional approach simplifies the assembly process regardless of the number of light sources required for the display area.
