Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual switching between flame, graphite furnace, and hydride generation devices is used, then measurement versatility is improved, but operation time and complexity increase
Solution Approach 1:
The patent integrates three separate atomization devices (flame atomizer, graphite furnace atomizer, and hydride atomizer) into a single integrated atomization device. The three atomizers are arranged side by side with their outlets aligned on the same horizontal line, allowing automatic switching between different measurement methods without manual intervention, thus reducing operation time while maintaining measurement versatility.
Solution Approach 2:
The integrated atomization device is designed to perform multiple functions by incorporating three different atomization methods (flame, graphite furnace, and hydride generation) into one device. This multi-functional design allows the system to measure various elements using different atomization techniques without requiring separate devices, thereby improving versatility while enabling automatic operation.
2Adaptability or versatility
If hydride generation device with multiple pipelines is used, then measurement capability for Hg, As, and Se is improved, but device complexity and failure rate increase
Solution Approach 1:
The patent merges the hydride generation device with the flame and graphite furnace atomization devices into a single integrated system. The hydride generation unit is combined with the other atomization methods, sharing common components such as the optical path and control system. This integration reduces the number of separate pipelines and interfaces while maintaining the capability to measure Hg, As, and Se.
Solution Approach 2:
The integrated atomization device provides universal functionality by incorporating flame, graphite furnace, and hydride generation capabilities in one system. This multi-functional design eliminates the need for separate hydride generation equipment, thereby reducing overall device complexity and the number of potential failure points while maintaining measurement capability for various elements.
3Adaptability or versatility
If hydride atomizer is manually switched, then measurement flexibility is improved, but atomizer damage and facility cost increase
Solution Approach 1:
The patent combines the hydride atomizer with flame and graphite furnace atomizers in an integrated device where all three atomizers are positioned side by side. The system includes an automatic switching mechanism that selects the appropriate atomizer based on the measurement requirements, eliminating manual switching operations that can cause damage to the atomizers.
Solution Approach 2:
The integrated atomization device incorporates an automatic switching system that autonomously selects and operates the appropriate atomizer (flame, graphite furnace, or hydride) based on the measurement method required. This self-service capability eliminates manual intervention in the switching process, preventing damage to the atomizers and improving their durability while maintaining measurement flexibility.
4Adaptability or versatility
If multiple separate atomization devices are used, then measurement versatility is improved, but device volume and space occupation increase
Solution Approach 1:
The patent merges three separate atomization devices (flame atomizer, graphite furnace atomizer, and hydride atomizer) into a single integrated atomization device. The three atomizers are arranged side by side in a compact configuration, sharing common components such as the optical path, detection system, and control unit. This integration significantly reduces the overall device volume and space occupation while maintaining the versatility to perform all three types of measurements.
