Solution Approach 1:

The existing measuring unit, originally designed for measuring reactant signals, is made multi-functional by enabling it to also detect mounted state through optical signal detection. The same light source and photodetector are used for both reactant measurement and cartridge positioning detection, eliminating the need for separate sensors.

Solution Approach 1:

The patent applies local quality by using a specific wavelength range (600-800nm) for mounted state detection that is distinct from the wavelength used for reactant measurement. This wavelength differentiation ensures that the optical signals for positioning detection do not interfere with reactant analysis, maintaining precision despite using the same hardware.

Inventive Principle:

Solution Approach 2:

The patent changes the optical parameter (wavelength) to enable the existing measuring unit to distinguish between mounted state detection and reactant measurement. By operating at different wavelengths or signal characteristics, the system achieves accurate mounted state detection without additional sensors.
