Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If multiple second projection material conveying mechanisms are provided to convey projection material upward, then the overall height of the device can be reduced, but the device complexity increases
Solution Approach 1:
The projection material conveying system is segmented into multiple second projection material conveying mechanisms, each responsible for conveying material upward from different locations. This segmentation allows the upward conveyance function to be distributed, reducing the overall height required for a single conveying path while maintaining effective material circulation.
Solution Approach 2:
The invention transitions from a single vertical conveying path to multiple parallel vertical paths arranged horizontally. By distributing the upward conveyance function across multiple dimensions (multiple conveying mechanisms side by side), the device achieves compact height without sacrificing material flow efficiency.
2Productivity
If a rotary hanger with multiple chambers is used to hold works, then the productivity is improved, but the device complexity increases
Solution Approach 1:
The rotary hanger is divided into multiple chambers, each capable of holding works independently. This segmentation allows parallel processing of multiple works simultaneously, improving productivity. Each chamber functions as an independent processing unit, enabling efficient utilization of the rotary mechanism.
Solution Approach 2:
The rotary hanger with multiple chambers serves multiple functions: holding multiple works simultaneously, rotating to position different chambers at the projection area, and enabling continuous processing. This multi-functional design improves productivity without requiring separate handling mechanisms for each work piece.
3Manufacturing precision
If partition materials are provided to divide the turntable into multiple chambers, then the manufacturing precision is improved, but the device complexity increases
Solution Approach 1:
Partition materials divide the turntable into multiple discrete chambers, creating well-defined processing zones. This segmentation ensures that each chamber maintains precise positioning and isolation, improving manufacturing precision by preventing interference between adjacent works and ensuring accurate projection material delivery to each chamber.

Function Achieved in This Case
This configuration reduces the overall height of the device, ensures balanced material transport, enhances classification performance for works with burrs and fine powders, and improves durability by adjusting belt tension and suppressing projection material bounce.
Implementation Method 1
centrifugal projectors (52A to 52D) which apply shot processing to the work W by projecting a projection material to the chamber (42) located in the projection material projection areas (18A to 18D) from outside in the radial direction of the turntable (34)
Implementation Method 2
bucket elevators (70A and 70B) as a second projection material conveying mechanism which convey the projection material conveyed by the lower screw conveyors (68A and 68B) upward
