Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional projector with a simple box shape is used, then the device structure is simple, but it is difficult to apply various oblique protrusions and adjust projection angles in the vehicle interior
Solution Approach 1:
The projecting module is made rotatable within the armrest housing, allowing dynamic adjustment of the projection angle. The rotating mechanism enables the projector to adapt to different projection surfaces (ceiling, rear window, side windows) while maintaining a relatively simple overall device structure.
Solution Approach 2:
The armrest-integrated projector design provides multi-functionality by enabling projection onto various surfaces (ceiling, rear window, side windows) from a single device location. The rotating projecting module allows one device to serve multiple projection purposes throughout the vehicle interior.
2Ease of operation
If a conventional projector without a handle is used, then the device structure is compact, but it is inconvenient to move and handle during use
Solution Approach 1:
The projector is merged with the armrest structure, combining the handling function (armrest) with the projection function. This integration allows the projector to be easily moved and positioned within the vehicle while maintaining a compact design, as the armrest itself serves as the carrying and positioning mechanism.
3Adaptability or versatility
If a projector is installed without rotation capability, then the device structure is simple, but it cannot project images to different locations (ceiling, rear, sides) within the vehicle
Solution Approach 1:
The projecting module incorporates a rotating mechanism that allows it to dynamically change its orientation and project images to different locations within the vehicle interior. The rotation capability enables adaptation to various projection surfaces while the module remains housed within the armrest structure.
4Ease of operation
If the projector is fixed in position, then the device structure is stable, but it cannot be easily repositioned or adjusted during vehicle use
Solution Approach 1:
The projecting module is designed with rotational capability within the armrest housing, allowing it to be repositioned and adjusted during vehicle use. The dynamic rotation mechanism enables easy repositioning while the module remains securely housed within the armrest structure, maintaining overall stability.
