Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional electron microscope is equipped with additional elements for cathodoluminescence collection, then cathodoluminescence collection function is achieved, but device complexity and cost increase
Solution Approach 1:
The invention divides the cathodoluminescence collection system into separate modular components: a sample holder unit and a mirror unit that can be independently installed and adjusted. This segmentation allows the collection function to be added without redesigning the entire microscope system, reducing overall complexity while maintaining functionality.
Solution Approach 2:
The mirror unit is designed with universal applicability to fit various electron microscope models. The mirrors are positioned to collect cathodoluminescence from multiple surfaces simultaneously, enabling one set of components to serve multiple collection functions that would otherwise require separate specialized systems.
2Adaptability or versatility
If conventional electron microscope is equipped with additional elements for cathodoluminescence collection, then cathodoluminescence collection function is achieved, but device cost increases
Solution Approach 1:
By segmenting the system into modular components, each part can be manufactured independently using standard fabrication processes. This avoids the need for expensive custom-integrated systems and allows for economies of scale in producing individual mirror units and sample holders that can be applied across multiple microscope models.
Solution Approach 2:
The mirror unit design serves as a replicable template that can be copied and adapted to different microscope models without requiring expensive custom engineering for each installation. The standardized interface and configuration allow the same design to be manufactured and installed universally.
3Device complexity
If cathodoluminescence is collected from one surface only, then collection structure is simple, but information quantity and accuracy are limited
Solution Approach 1:
The mirror unit is configured with multiple mirrors positioned to collect cathodoluminescence from both the upper and lower surfaces of the sample simultaneously. This multi-surface collection capability is achieved through a single integrated mirror unit that performs multiple collection functions, doubling the information obtained without proportionally increasing system complexity.
Solution Approach 2:
The invention transitions from single-surface collection to multi-surface collection by adding the vertical dimension of light collection paths. Mirrors are positioned above and below the sample plane to capture cathodoluminescence from opposite surfaces, effectively utilizing three-dimensional space to gather information from multiple dimensions simultaneously.
