Solution Approach 2:

The electronic scale performs self-service by automatically calculating processing amount correction without requiring external manual intervention. The system uses its own embedded processor and storage to retrieve coefficients and perform calculations autonomously, reducing dependency on operator expertise and time.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If experience-based coefficients are used for processing amount correction, then adaptability to different product types is maintained, but transparency and trustworthiness decrease

Engineering Contradiction:

Improveflexibility in cost calculationVSAvoidopacity in cost determination

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent implements feedback by displaying both the original weight measurement and the calculated processing amount correction on the electronic scale's display unit. This allows orderers to verify the calculation process and results in real-time, providing transparency while maintaining the ability to handle different product types through programmable coefficients.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The electronic scale achieves universality by being able to handle multiple product types and calculation scenarios through a single device. The system can store multiple sets of coefficients for different precious metal products and processing types, providing both transparency through standardized calculations and adaptability to various business needs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Loss of information

If standardized processing amount correction is implemented, then transparency for orderers is improved, but complexity of system implementation increases

Engineering Contradiction:

Improveopacity in cost determinationVSAvoidsystem implementation complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent merges the weighing function and the calculation function into a single integrated electronic scale system. By combining the weight sensor, processor, memory for storing coefficients, and display unit into one device, the system achieves transparency without requiring separate complex systems for measurement and calculation.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system manages complexity through parameter changes by allowing flexible configuration of coefficients and calculation methods through software programming. This enables standardized transparent calculations to be implemented without hardware complexity, as the adaptability is achieved through changeable software parameters rather than complex physical structures.

Inventive Principle:
