Engineering Contradiction Analysis
1Volume of moving object
If the analyzer apparatus is miniaturized by housing all units in a compact housing, then the portability and compactness are improved, but temperature-induced variations in circuitry outputs increase leading to reduced detection precision
Solution Approach 1:
The patent implements temperature detecting units that continuously monitor the temperature of ion drive circuitry and field drive circuitry, feeding this information back to correction units that adjust output settings in real-time. This feedback mechanism compensates for temperature-induced variations, maintaining detection precision even in compact housings where thermal conditions may fluctuate.
Solution Approach 2:
The correction units dynamically adjust output parameters (voltage, current settings) of the ion drive and field drive circuitry based on detected temperature values. By changing these parameters in response to temperature variations, the system maintains stable performance and linearity despite thermal fluctuations in the compact housing environment.
2Measurement precision
If temperature compensation functions are added to correct circuitry outputs, then detection precision is improved, but device complexity increases
Solution Approach 1:
The control unit is designed to perform multiple functions: it controls the outputs of ion drive and field drive circuitry, processes temperature data from detecting units, and executes correction calculations. By making the control unit multi-functional, the patent avoids adding separate dedicated correction devices, thereby improving precision without proportionally increasing overall device complexity.
Solution Approach 2:
The system performs self-diagnosis and self-correction by using temperature detecting units to monitor its own operational conditions and automatically adjusting circuitry outputs through correction units. This self-service capability eliminates the need for external calibration equipment or manual adjustments, improving precision while keeping the added complexity minimal and integrated within the existing system architecture.
