Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the movable body is shifted between upright and tilt positions using a driving device, then the visual appeal and user recognition of displayed information is improved, but the device complexity increases
Solution Approach 1:
The display system employs a movable body that can dynamically shift between upright and tilt positions to enhance visual appeal and user recognition. This dynamic positioning capability allows the display to adapt to different viewing conditions and improve marketability without requiring completely separate display systems for each position.
Solution Approach 2:
The guide rail structure serves multiple functions: it guides the movable body during position transitions, provides structural support, and enables both upright and tilt positions to be achieved through a single mechanism. This multi-functionality reduces the need for additional components and maintains ease of manufacture.
2Ease of operation
If an arc-shaped guide portion is used during initial application of driving force, then the shift operation smoothness is improved, but the guide device complexity increases
Solution Approach 1:
The guide rail incorporates an arc-shaped guide portion that provides curved guidance during the initial phase of the shifting operation. This curvature allows for smoother transitions by distributing the driving force more evenly, reducing sudden jerks or impacts, and improving overall shift operation smoothness.
Solution Approach 2:
The arc-shaped guide portion is positioned to engage during the initial application of driving force, preparing the movable body for smooth transition before the linear guide portion takes over. This preliminary curved guidance ensures that the shifting operation begins smoothly, preventing operational shocks.
3Manufacturing precision
If a linear guide portion is used after initial application of driving force, then the manufacturing precision is improved, but the guide device complexity increases
Solution Approach 1:
The guide rail is divided into two distinct portions: an arc-shaped guide portion for initial smooth transition and a linear guide portion for precise positioning. This segmentation allows each portion to be optimized for its specific function while maintaining overall manufacturability, as each segment can be manufactured using standard techniques.
Solution Approach 2:
The transition from arc-shaped to linear guidance provides a progressive refinement of the movable body's position. The curved portion handles the dynamic initial movement, while the linear portion ensures precise final positioning, achieving high manufacturing precision without requiring the entire guide rail to be complex.
