Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large number of light emitting devices are used to display images in fixed quadrangular shapes, then the display coverage and image quality are improved, but the material cost and device complexity increase
Solution Approach 1:
The patent applies the dynamics principle by using rotating substrates instead of fixed display panels. The substrates rotate around a central axis, allowing a limited number of light emitting devices to cover a larger display area over time. This dynamic configuration enables the same physical components to serve multiple spatial positions, thereby expanding the effective display area without proportionally increasing the number of light emitting devices.
Solution Approach 2:
The patent introduces temporal dimension to the display system through rotation. Instead of arranging light emitting devices only in spatial dimensions to cover the display area, the system adds time as another dimension where the same devices can occupy different positions sequentially. This dimensional transformation allows fewer devices to achieve the same or greater display coverage compared to static arrangements.
2Ease of manufacture
If fixed quadrangular display structures are used, then the manufacturing process is simplified, but the versatility and adaptability of display shapes are reduced
Solution Approach 1:
The rotating substrate mechanism transforms a static manufacturing challenge into a dynamic solution. While each individual substrate maintains a simple structure for ease of manufacture, the rotational assembly enables these simple components to create complex display patterns and shapes. The system achieves versatility not through complex individual parts but through the dynamic arrangement of simple parts.
Solution Approach 2:
The rotating substrate system serves multiple functions: it can display images in various shapes (circles, squares, triangles, etc.), adjust display areas dynamically, and create different visual effects. This multi-functional capability allows a single manufacturing process to produce diverse display configurations, thereby achieving both manufacturing simplicity and display versatility.
3Adaptability or versatility
If rotating plates with substrates are used to display various shapes, then the versatility and display area are improved, but the device complexity increases
Solution Approach 1:
The display system is segmented into modular components: multiple substrates, rotating plates, and a central rotation mechanism. Each substrate can be independently manufactured and assembled, allowing for simplified individual component design. The segmentation enables the complex overall function to be achieved through the coordinated operation of simpler, standardized parts.
Solution Approach 2:
The patent merges multiple functions into the rotating substrate assembly: the substrates serve as both the structural support and the light-emitting platform, while the rotation mechanism simultaneously achieves positioning, shape formation, and display area adjustment. This functional merging reduces the need for separate components, thereby managing device complexity while maintaining versatility.
4Adaptability or versatility
If inorganic light emitting devices are mounted on rotating substrates, then the display can achieve various angles and shapes, but the alignment precision and manufacturing difficulty increase
Solution Approach 1:
The patent applies local quality by ensuring that each substrate maintains precise alignment and uniform properties at its local mounting position. The rotating mechanism is designed so that each substrate's local orientation and positioning are optimized for its specific location on the rotating plate. This localized precision approach allows the overall system to achieve high display quality without requiring every component to be perfectly precise in all dimensions.
