Solution Overview

Problem

Spectrometers face calibration challenges when the control module is damaged or lost, as specific optomechanical parameters are not stored in other control modules, leading to inaccurate calibration and increased manufacturing and maintenance costs.

Innovation Solution

Incorporating a memory device within the optomechanical module's sampling device to pre-store optomechanical parameters, allowing the control module to read and calibrate the optomechanical engine independently, eliminating the need for a specific control module and preventing incompatibility issues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If optomechanical parameters are stored in the control module memory, then calibration accuracy is improved, but the system reliability deteriorates when the control module is damaged or lost

Engineering Contradiction:

Improvewavelength calibration accuracyVSAvoidcalibration capability when control module is damaged

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The patent divides the storage function into two separate locations: the control module memory and the optomechanical module memory. This segmentation ensures that calibration parameters are not solely dependent on the control module, allowing the optomechanical module to retain calibration capability even when the control module is damaged or replaced.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent creates a copy of the optomechanical parameters in the optomechanical module's own memory. This copying mechanism ensures that the critical calibration data is replicated and stored in a location that remains accessible even when the control module fails, thereby improving system reliability.

Inventive Principle:

Principle #26Copying

2Measurement precision

If specific control modules are paired with specific optomechanical modules, then calibration accuracy is improved, but the device complexity and manufacturing cost increase

Engineering Contradiction:

Improvecalibration accuracyVSAvoidcontrol module pairing requirements

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent implements a universal storage solution where the optomechanical parameters are stored in the optomechanical module itself, making the calibration data accessible to any control module. This eliminates the need for specific pairings between control modules and optomechanical modules, allowing any control module to work with any optomechanical module while maintaining calibration accuracy.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If optomechanical parameters are stored externally, then adaptability is improved, but the loss of information risk increases when control module is damaged

Engineering Contradiction:

Improvecontrol module interchangeabilityVSAvoidoptomechanical parameter loss

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent prepares for potential control module failure by pre-storing the optomechanical parameters in the optomechanical module's memory before any damage occurs. This beforehand cushioning ensures that even if the control module is damaged or lost, the critical calibration information remains preserved and accessible, preventing information loss.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)
