Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual adjustment of control parameters is performed for each constituent element, then individual characteristics can be accommodated, but significant time and labor are required

Engineering Contradiction:
Improvecontrol parameter accuracyVSAvoidparameter determination time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system pre-acquires correspondence relationships between model identification information and parameter values before actual operation. Multiple determination models are prepared in advance, each with associated parameter values stored in a database. When a constituent element needs parameter determination, the system simply queries the pre-prepared correspondence relationship rather than performing manual adjustment, thus eliminating time-consuming manual work while maintaining accurate parameter selection based on individual characteristics.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If manual teaching operation is performed for each constituent element and processing recipe, then proper control parameters can be determined, but the work is extremely time-consuming

Engineering Contradiction:
Improveoperation simplicityVSAvoidsetup efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The system creates determination models that copy and represent the characteristics of constituent elements. Instead of manually teaching each individual element, the system builds determination models based on model identification information that captures the essential characteristics. These models serve as templates that can be quickly queried and applied, replacing time-consuming manual teaching operations with automated model-based parameter determination.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system transforms the manual adjustment process into an automated parameter query process. By establishing correspondence relationships between model identification information and parameter values, the system changes the operational mode from manual teaching and adjustment to automated retrieval and application of parameters, significantly improving setup efficiency while maintaining operational simplicity.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If multiple determination models are used to handle individual differences, then accurate parameter determination is possible, but system complexity increases

Engineering Contradiction:
Improvedetermination accuracyVSAvoidsystem structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system introduces model identification information as an intermediary between the constituent element and the parameter determination process. Instead of directly handling complex individual characteristics of each element, the system uses model identification information to select appropriate determination models. This intermediary layer simplifies the system structure by providing a standardized interface for model selection while maintaining high determination accuracy through the use of multiple specialized determination models.

Inventive Principle:
Principle #24Intermediary (Mediator)
