Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple component supplying units are used for each nozzle spindle, then component supply capability is improved, but device complexity and cost increase
Solution Approach 1:
A single component supplying unit is designed to serve multiple nozzle spindles simultaneously. The supplying unit includes a component storage area and a transfer mechanism that can supply components to different nozzle spindles in sequence or parallel, making one unit perform the function of multiple units and reducing overall system complexity
Solution Approach 2:
Multiple component supply functions are merged into one integrated supplying unit. Instead of having separate supplying units for each nozzle spindle, the patent combines them into a single unit that manages component distribution to multiple nozzles, thereby reducing the total number of components and simplifying the system
2Adaptability or versatility
If fixed interval suction nozzles are used, then manufacturing simplicity is maintained, but adaptability to different component spacing is reduced
Solution Approach 1:
The suction nozzles are designed with adjustable spacing capability, allowing the distance between nozzles to be dynamically changed. This enables the system to adapt to different component pitch requirements on substrates. The adjustable mechanism may include movable nozzle mounts or reconfigurable nozzle arrays that can be positioned at various intervals
Solution Approach 2:
The spacing parameter of the suction nozzles is made variable rather than fixed. By allowing the interval between nozzles to be changed, the system can accommodate different component layouts and pitch specifications, enhancing versatility without requiring multiple fixed nozzle sets
3Reliability
If multiple component supplying units are used, then component supply reliability is improved, but manufacturing cost increases
Solution Approach 1:
One component supplying unit is designed to perform the supply function for multiple nozzle spindles, reducing the total number of units needed. This single unit incorporates all necessary components for reliable component supply, including storage, retrieval, and transfer mechanisms, thereby maintaining reliability while reducing manufacturing costs associated with producing multiple units
