Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If lower receiving pins are placed at arbitrary locations on the lower receiving base to achieve high-precision arrangement, then manufacturing precision is improved, but pin interference during transfer operations occurs
Solution Approach 1:
The patent applies preliminary action by setting temporary placement areas in advance where pins are temporarily positioned before final arrangement. This pre-planned intermediate storage allows pins to be transferred without interference while achieving precise arbitrary positioning, as the temporary areas are predetermined to avoid collision paths during transfer operations.
Solution Approach 2:
The patent segments the pin transfer process into multiple stages: first transferring pins to temporary placement areas, then from temporary areas to final arbitrary positions. This segmentation separates the transfer path from the final position, allowing interference-free transfer while achieving high-precision arbitrary placement.
2Object-affected harmful factors
If elevation stroke is increased to prevent pin interference during transfer, then pin interference is prevented, but equipment cost increases
Solution Approach 1:
The patent introduces a spatial dimension solution by creating temporary placement areas at different locations on the lower receiving base. Instead of increasing vertical elevation stroke, the system uses horizontal spatial separation through temporary areas to avoid pin interference, thereby preventing the need for increased equipment stroke and associated cost increases.
3Object-affected harmful factors
If elevation stroke is increased to prevent pin interference, then pin interference is prevented, but operation time increases and productivity decreases
Solution Approach 1:
By preliminarily designating temporary placement areas and pre-planning transfer sequences, the system avoids interference without requiring additional elevation movements. This preliminary arrangement optimization maintains efficient operation time while preventing pin interference, thus preserving productivity.
Solution Approach 2:
The patent enables continuous pin transfer operations by using temporary placement areas that allow seamless transitions between pins. The transfer process maintains continuous useful action without interruptions for additional elevation strokes or repositioning, thereby preventing productivity loss while avoiding interference.
4Ease of operation
If lattice pattern pin attachment holes are used in the lower receiving base, then pin transfer is simple, but arrangement flexibility is restricted
Solution Approach 1:
The patent segments the pin arrangement system into two functional parts: lattice-patterned temporary placement areas for simple transfer operations, and arbitrary final positions for flexible arrangement. This segmentation allows the system to enjoy the simplicity of lattice-based transfer while achieving the flexibility of arbitrary positioning through the two-stage process.
Solution Approach 2:
The lower receiving base is designed with multi-functionality, serving both as a platform for lattice-patterned temporary placement (for simple transfer) and as a destination for arbitrary pin positions (for flexible arrangement). This universal design allows the same base structure to support both operational simplicity and arrangement versatility.

AI summary
A pre-array temporary placement area A2 and a post-return temporary placement area A3 are set along with a lower receiving area A1. Temporary placement positions TP for lower receiving pins 22 in the pre-array temporary placement area A2 and the post-return temporary placement area A3 are previously assigned in consideration of requirements for preventing occurrence of interference between the lower receiving pins 22, which would otherwise occur during transfer of the lower receiving pins 22, and in accordance with array positions AP of the lower receiving pins 22 in the lower receiving area A1. Further, a transfer sequence is set in accordance with array positions AP.
