Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the liquid supply and discharge module is fixed together with the objective lens, then the liquid supply and discharge function is integrated, but the system cannot match different objective lenses and lacks compatibility
Solution Approach 1:
The liquid supply and discharge system is segmented from the objective lens structure into an independent movable device. The liquid supply conduit assembly and liquid discharge conduit assembly are separate from the objective lens, allowing the system to accommodate different lens specifications while maintaining dedicated liquid management functionality.
Solution Approach 2:
The movable liquid supply and discharge device is designed with universal applicability to work with objective lenses of different sizes and specifications. The independent conduit assemblies can be positioned and adjusted to serve multiple lens types without requiring lens-specific integration.
2Productivity
If the objective lens waits for liquid supply and discharge operations sequentially, then the liquid operations are performed in order, but the objective lens cannot perform photography and other tasks during this time, consuming a lot of time
Solution Approach 1:
The liquid supply and discharge operations are performed in advance and in parallel before the objective lens is needed for photography or other tasks. The movable device prepares the working surface by supplying liquid and removing previous liquid, so that when the lens moves to the working position, the liquid operations are already complete, eliminating wait time.
Solution Approach 2:
The system maintains continuous productivity by overlapping liquid supply/discharge operations with objective lens positioning and other preparatory actions. The movable liquid management device operates independently and continuously, ensuring that liquid operations do not interrupt the main photography workflow.
3Productivity
If the liquid supply and discharge operations are performed sequentially in serial logical sequence, then the operations are simple to control, but the total operation time is extended and efficiency is reduced
Solution Approach 1:
The liquid supply and discharge functions are segmented into separate conduit assemblies that can operate independently and in parallel. The liquid supply conduit assembly and liquid discharge conduit assembly are controlled separately, enabling simultaneous operations without complex interdependencies.
Solution Approach 2:
The system dynamically coordinates parallel liquid supply and discharge operations through the movable device architecture. The independent conduit assemblies can be activated, deactivated, or adjusted dynamically based on operational needs, allowing flexible parallel execution while maintaining manageable control complexity.
