Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the objective lens is exposed to ambient temperature changes, then the optical equipment can operate in various environmental conditions, but the temperature of the objective lens fluctuates causing performance changes
Solution Approach 1:
The patent divides the thermal control system into separate functional components: an insulated chamber to isolate the objective lens from ambient temperature changes, a heater to actively heat the lens, and a cooler to actively cool the lens. This segmentation allows independent control of heating and cooling functions while maintaining temperature stability within the chamber.
Solution Approach 2:
The patent introduces an insulated chamber as an intermediary barrier between the objective lens and the ambient environment. This chamber with insulated walls mediates thermal interaction, reducing heat transfer between the external environment and the objective lens, thereby maintaining temperature constancy while allowing environmental adaptability.
2Temperature
If a temperature control system is added to maintain objective lens temperature, then temperature constancy is improved, but the device complexity increases
Solution Approach 1:
The patent combines the heater, cooler, temperature sensor, and control unit into an integrated temperature control system within the insulated chamber. The control unit receives temperature signals from the sensor and automatically adjusts the heater or cooler, merging multiple components into a coordinated system that maintains temperature stability without requiring complex external control mechanisms.
Solution Approach 2:
The patent implements a feedback control mechanism where a temperature sensor continuously monitors the objective lens temperature and provides signals to the control unit. The control unit compares the measured temperature with the target temperature and automatically adjusts the heater or cooler accordingly, creating a closed-loop feedback system that maintains temperature constancy with minimal manual intervention.
3Loss of energy
If insulation is applied to the objective lens, then heat loss is reduced and temperature stability is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent employs a nested structure where the objective lens is placed inside an insulated chamber, which itself is housed within the larger optical equipment housing. The insulated chamber with its insulated walls acts as a nested thermal barrier, reducing heat loss from the objective lens while maintaining a compact overall structure that is relatively straightforward to manufacture and assemble.
