Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pipette chips are conveyed by stirring them in a hopper, then the chips can be supplied one at a time to the dispensing nozzle, but static electricity occurs due to friction between chips causing them to attach to the supply path and each other
Solution Approach 1:
The invention introduces a grounding mechanism that converts the harmful static electricity effect into a beneficial one by providing a discharge path. The grounding electrode connected to the hopper wall allows static charges accumulated during chip stirring to be discharged to ground, preventing chip adhesion while maintaining the efficient stirring-based supply method.
Solution Approach 2:
The invention introduces a grounding electrode as an intermediary element between the charged pipette chips and the ground. This mediator provides a controlled path for static charge discharge, preventing direct adhesion of chips to the supply path while enabling continuous operation.
2Productivity
If pipette chips are conveyed upward by a bucket conveyor through a shoot to the hopper, then the chips can be supplied continuously, but the chips accumulate in the shoot and hopper causing conveyance failure
Solution Approach 1:
The invention introduces a detection mechanism that monitors chip accumulation in the shoot and provides feedback to the control unit. When accumulation is detected, the system automatically adjusts the conveyor operation to discharge excess chips, preventing conveyance failure while maintaining continuous supply capability.
Solution Approach 2:
The invention makes the chip supply system dynamic by enabling real-time adjustment of conveyor operation based on accumulation detection. The system can switch between normal operation and discharge mode, optimizing both continuous supply and reliability.
