Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If oven heating or standard ablation methods are used to generate atomic sources, then atom production is achieved, but control over on/off time and precise material quantity is poor
Solution Approach 1:
The patent changes the physical state parameter of the analyte by embedding it in an epoxy matrix, transforming it from a bulk solid to a distributed solid-liquid composite. This enables precise control of atom release by controlling the laser ablation parameters of the epoxy matrix, achieving better on/off time control and material quantity precision without significantly increasing device complexity
Solution Approach 2:
The patent segments the analyte material into small embedded particles within the epoxy matrix. This segmentation allows the laser to ablate the epoxy matrix and release atoms in a controlled manner, improving control precision by releasing atoms gradually from multiple embedded particles rather than from a bulk material
2Reliability
If standard ablation methods are used, then atom sources are generated, but mechanical stability and handling of small amounts of analyte are difficult
Solution Approach 1:
The patent creates a composite material by embedding analyte particles in an epoxy matrix. This composite structure provides mechanical stability through the epoxy while preserving the analyte for atom release. The epoxy matrix acts as a stable host that protects small amounts of analyte during handling and transport, solving both the mechanical stability and handling ease problems
Solution Approach 2:
The epoxy matrix serves as an intermediary between the analyte and the external environment. It protects the analyte during handling and storage while allowing controlled release of atoms when the epoxy is ablated by the laser, thus improving both mechanical stability and handling ease without compromising the analyte's function
3Loss of substance
If precise control of analyte amount is required, then material waste is reduced, but fabrication complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-embedding the analyte in the epoxy matrix during target fabrication. This allows precise control of the analyte amount to be used in each experiment, as the epoxy matrix can be ablated to release only the required amount of atoms. The excess epoxy remains on the target and can be removed or reused, reducing material waste without significantly increasing fabrication complexity
