Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional single-function rotatable tray is used, then the structure is simple, but the adaptability is poor
Solution Approach 1:
The patent applies the dynamics principle by introducing a revolute pair assembly that enables the rotatable tray to switch between different functional states (first state for rotation, second state for positioning). This dynamic state switching allows the same structure to adapt to different operational requirements, thereby improving adaptability without requiring multiple separate components.
Solution Approach 2:
The patent implements universality by designing the rotatable tray mechanism to perform multiple functions through state switching. The revolute pair assembly allows the tray to function as both a rotatable component (when in first state) and a positioned component (when in second state), making a single structure serve multiple purposes and thereby improving adaptability.
2Adaptability or versatility
If the revolute pair assembly is added to enable state switching, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the rotatable tray mechanism into distinct functional components: the base, the rotatable tray, and the revolute pair assembly. This segmentation allows each component to have a specific function while working together as an integrated system, managing complexity through modular design.
Solution Approach 2:
The patent uses the revolute pair assembly as an intermediary mechanism between the base and the rotatable tray. This intermediary component enables state switching and functional transformation without requiring direct complex interactions between the base and tray, thereby managing overall system complexity while achieving flexibility.

AI summary
A rotatable tray mechanism includes a base, a rotatable tray, and a revolute pair assembly and an actuating unit arranged between the base and the rotatable tray. At least one of the rotatable tray and the base includes a revolving shaft arranged on at least one edge. The revolute pair assembly is arranged on at least one of the base and the rotatable tray and is at a location opposite to the revolving shaft. One revolving shaft mates with at least one revolute pair assembly including a revolute pair and an enable mechanism, wherein the revolute pair has a first state and a second state. The enable mechanism is enabling the revolute pair to switch over between the first state and the second state. When the revolute pair is in the first state, the rotatable tray rotates with respect to the base by taking the revolving shaft as a rotating shaft and taking the revolute pair as support of the revolving shaft when the actuating unit applies an acting force, wherein the direction of the acting force applying the rotatable tray is a direction far away from the base.
