Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual disassembly using heat gun and tweezers is used, then operational flexibility is maintained, but productivity is low and precision is poor
Solution Approach 1:
The patent combines multiple functions (heating, suction, positioning, and disassembly) into a single integrated automated apparatus. The heating assembly and suction assembly are merged into one coordinated system that automatically performs sequential operations, eliminating the need for separate manual tools and significantly improving productivity while maintaining controlled complexity through functional integration.
Solution Approach 2:
The automated apparatus performs disassembly operations autonomously without requiring manual intervention for each step. The system self-regulates the heating process, activates suction automatically, and coordinates movements through programmable control, transforming a manual labor-intensive process into an automated self-service system that boosts productivity.
2Manufacturing precision
If automated heating and suction assembly is used, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The apparatus is divided into distinct functional modules: a positioning assembly for precise circuit board positioning, a heating assembly for controlled thermal processing, and a suction assembly for component removal. Each module independently contributes to the overall precision, allowing the system to achieve high manufacturing precision while managing complexity through modular segmentation.
Solution Approach 2:
The positioning assembly acts as an intermediary between the circuit board and the heating/suction operations. It ensures precise positioning and alignment before the heating and suction processes begin, thereby achieving high disassembly precision without requiring the entire apparatus to be overly complex.
3Measurement precision
If automated positioning assembly is used, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The positioning assembly is designed as a separate, dedicated module with its own positioning mechanisms and control systems. This segmentation allows it to focus solely on achieving measurement and positioning precision without adding unnecessary complexity to the entire apparatus. The modular design enables independent optimization of positioning accuracy.

AI summary
An apparatus for disassembling an electronic component from a circuit board includes a base, a controller, a positioning assembly, and a heating and suction assembly. The controller is fixed to the base. The positioning assembly is arranged on the base and coupled to the controller. The positioning assembly is configured to be controlled by the controller to position the circuit board at a first predetermined position. The heating and suction assembly is movably arranged on the base and coupled to the controller. The heating and suction assembly is moved to a second predetermined position to heat the electronic component and moved to a third predetermined position to attract and hold the heated electronic component by suction, whereby the electronic component is disassembled from the circuit board.
