Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple high-power lasers are used to cool source material atoms, then cooling effectiveness is improved, but device complexity and size increase
Solution Approach 1:
The patent combines multiple laser beams into a single laser by using a conical mirror concentrator that focuses light from one laser source to multiple focal points where atoms are cooled. This merging approach maintains the cooling effectiveness of multiple lasers while reducing the actual number of laser devices needed from five to one.
Solution Approach 2:
The conical mirror concentrator acts as an intermediary device that takes light from a single laser and redistributes it to multiple locations. This intermediary component enables the system to achieve the effect of multiple lasers while using only one, thereby reducing complexity without sacrificing cooling performance.
2Reliability
If multiple lasers are used to cool atoms, then cooling performance is improved, but alignment time and adjustment complexity increase
Solution Approach 1:
By merging the function of multiple lasers into a single laser through the conical mirror concentrator, the system eliminates the need for aligning multiple independent laser beams. The single laser beam is automatically focused by the conical geometry to the required locations, dramatically reducing alignment time and complexity.
3Use of energy by moving object
If a conical mirror concentrator is used to focus light to an axis, then optical efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent optimizes the conical angle parameter to balance optical efficiency and manufacturing feasibility. By carefully selecting the cone angle, the system achieves effective light focusing while maintaining manufacturability with standard precision capabilities, avoiding excessively tight tolerance requirements.
