Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If robots and suckers are used to separate and transport discs or sheets, then the separation function is achieved, but the structure becomes complex and bulky, occupying too much space and requiring complicated control
Solution Approach 1:
The patent extracts the essential separation function from complex robotic systems and implements it through a dedicated separation mechanism with a pressing component and lifting assembly. This removes unnecessary complexity while retaining the core functionality of separating stacked material trays
Solution Approach 2:
The separation mechanism uses the material trays themselves as part of the separation process. The pressing component presses down on the upper material tray while the lifting assembly raises the lower tray, utilizing the trays' own structure and weight to facilitate separation without requiring external robotic manipulation
2Reliability
If robots and suckers are used to separate and transport discs or sheets, then the separation function is achieved, but the structure becomes bulky and occupies too much space
Solution Approach 1:
The separation mechanism is integrated with the storage rack structure. The pressing component is mounted on the storage rack, and the lifting assembly works in conjunction with the rack's frame, merging the separation function with the existing storage infrastructure to minimize additional space requirements
Solution Approach 2:
The separation mechanism operates vertically within the existing storage rack height, utilizing the vertical dimension rather than requiring additional horizontal space. The pressing component moves vertically to press down on trays, and the lifting assembly raises trays vertically, keeping the footprint compact
3Reliability
If robots and suckers are used to separate and transport discs or sheets, then the separation function is achieved, but the control becomes complicated
Solution Approach 1:
The separation mechanism automatically executes the separation process through coordinated movement of the pressing component and lifting assembly. Once activated, the system self-regulates the pressing and lifting actions based on the mechanical interaction with the material trays, eliminating the need for complex control algorithms required by robotic systems
Solution Approach 2:
The pressing component acts as an intermediary between the control system and the material trays. It translates simple control signals into effective separation action by mechanically pressing down on the trays, while the lifting assembly provides the counterbalancing upward force, creating a straightforward control mechanism
4Reliability
If a clamping mechanism with rotating shafts and cams is used, then the clamping stability is improved, but the device complexity increases
Solution Approach 1:
The rotating shafts with cams provide periodic clamping action as they rotate. The cams are positioned to engage with the material trays at specific rotational positions, creating regular clamping cycles that ensure stable gripping without requiring continuous complex control
Solution Approach 2:
The cams utilize curved surfaces to convert rotational motion into the desired clamping motion. The cam profiles are designed with specific curvature to provide smooth engagement and disengagement of the clamping blocks, ensuring stable clamping while simplifying the mechanical design compared to linear actuation systems

AI summary
A separation mechanism includes a body frame, a clamping mechanism, a lifting assembly, and a material frame. The clamping mechanism includes a driving motor mounted on the body frame, two rotating shafts driven by the driving motor, and at least one clamping assembly. A separation area is formed between the two rotating shafts. The clamping assembly includes a main cam mounted on the respective rotating shaft and a main clamping block following the main cam. The main cams being configured that when the rotating shafts rotate to an initial station, the main cams drive the main clamping blocks to withdraw to release the material tray, and when the rotating shafts rotate to a clamping station, the main cams drive the main clamping blocks to stretch to clamp the material tray. A feeding device is also provided, which is simple in structure, small in size, and convenient to control.
