Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the screen position and angle are fixed, then the device structure is simple, but the video expression variety is limited
Solution Approach 1:
The patent applies dynamics by making the screen and projection device movable rather than fixed. The screen can be adjusted in height and angle through a support mechanism with adjustment mechanisms, and the projection device can change its projection direction. This dynamic capability enables diverse video expressions while maintaining manageable structural complexity through modular design.
Solution Approach 2:
The carrying platform serves multiple functions: it supports the projection device, provides mobility through wheels, and incorporates the projection direction variable part. This multi-functionality reduces the need for separate components, thereby increasing video expression variety without proportionally increasing device complexity.
2Adaptability or versatility
If the screen position is adjustable in height and angle, then the video expression variety increases, but the installation complexity increases
Solution Approach 1:
The support mechanism is segmented into multiple independent adjustment mechanisms - one for height adjustment and another for angle adjustment. This segmentation allows each mechanism to be optimized independently and simplifies the overall installation process by breaking down complex adjustments into manageable, independent operations.
Solution Approach 2:
The screen support system is designed with dynamic adjustment capabilities, allowing the screen to be positioned at various heights and angles. The adjustment mechanisms enable easy modification of screen position without requiring complex installation procedures, as the system is designed to be reconfigurable rather than fixed.
3Adaptability or versatility
If the projection direction is variable, then the video expression variety increases, but the device complexity increases
Solution Approach 1:
The projection direction variable part is merged with the carrying platform, combining the functions of support and direction control into a single integrated structure. This merging reduces the need for separate mounting structures and simplifies the overall device architecture while maintaining projection direction flexibility.
Solution Approach 2:
The carrying platform is designed as a multi-functional component that simultaneously provides mechanical support, mobility through wheels, and projection direction control. This universality increases video expression variety without requiring additional dedicated structures, thereby limiting the increase in device complexity.
