Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual mounting and collection of balls is performed, then the process is flexible and easy to operate, but the productivity is low and time-consuming
Solution Approach 1:
The ball support member automatically supports balls during mounting and collects them during disassembly through its swinging motion, eliminating the need for separate manual operations. The device performs ball mounting and collection through self-contained mechanisms that reduce dependency on external manual intervention, thereby improving productivity without proportionally increasing device complexity.
Solution Approach 2:
The ball support member is designed to swing between different positions (mounting position and collection position) to dynamically adapt its function. This dynamic movement allows the same component to perform multiple operations (mounting and collection) sequentially, enhancing productivity while maintaining reasonable device complexity through component reuse.
2Loss of time
If balls are mounted and collected manually, then the assembly process is simple, but the time required for assembly and disassembly is excessive
Solution Approach 1:
The ball support member automatically supports balls during mounting and collects them during disassembly through its swinging motion, eliminating the need for separate manual operations. The device performs ball mounting and collection through self-contained mechanisms that reduce dependency on external manual intervention, thereby improving productivity without proportionally increasing device complexity.
Solution Approach 2:
The swinging motion of the ball support member enables continuous operation between mounting and collection phases. The mechanism transitions smoothly between positions without idle time, maintaining continuous useful action throughout the process. This continuity reduces the total time required while the automated nature of the swing reduces operational complexity.
3Productivity
If automation is introduced for ball mounting and collection, then productivity is enhanced, but the device complexity increases
Solution Approach 1:
The ball support member serves multiple functions: supporting balls during mounting, positioning balls precisely, and collecting balls during disassembly. This multi-functionality reduces the need for separate dedicated components for each operation, thereby enhancing productivity while limiting the increase in device complexity through component consolidation.
Solution Approach 2:
The device is segmented into functional modules (ball support member, rotation mechanism, displacement mechanism) that can operate independently but coordinate together. This segmentation allows each module to be optimized for its specific function while maintaining overall system productivity, and facilitates easier maintenance and operation despite the automated nature of the system.

AI summary
Provided is an assembling device for an angular ball bearing, the assembling device being capable of quickly installing and collecting balls for the angular ball bearing. An angular ball bearing (1) has an inner ring (10), an outer ring (20), and balls (30), and an assembling device (50) can install balls (30) into the gap (S) between the inner ring (10) and the outer ring (20) and can collect the balls (30) from the gap (S). The assembling device (50) is provided with: an inner ring jig (64) which can rotate the inner ring (10) and the outer ring (20) relative to each other; an outer ring jig which can displace the inner ring (10) and the outer ring (20) relative to each other along a plane perpendicular to the axial direction; a curved arm (78) which supports the balls (30) by the upper surface (78c) of the curved arm (78), can rotate in the circumferential direction, and can be displaced in the axial direction; and a ball collection pin (68) which, while the balls (30) are installed in the gap (S), can be disposed in a portion which is not occupied by the balls (30) and which can prevent the circumferential displacement of the balls (30).
