1Productivity

If a fixed production sequence is used in manufacturing cells, then the production process is simple to manage, but setup times increase and overall throughput decreases

Engineering Contradiction:
Improveoverall throughputVSAvoidproduction sequence optimization system
Core Design Contradiction:

Solution Approach 1:

The patent implements dynamic production sequences that automatically adapt based on real-time machine status, workload, and capabilities. The system continuously optimizes the production sequence by evaluating current conditions and adjusting the processing order of workpieces across multiple manufacturing cells, transforming a static fixed sequence into a dynamic adaptive sequence that maximizes throughput while managing complexity through automation.

Inventive Principle:
Principle #15Dynamics

2Productivity

If production sequences are optimized dynamically, then setup times are reduced and throughput increases, but energy consumption increases

Engineering Contradiction:
Improveoverall throughputVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The system optimizes production sequences by changing operational parameters dynamically, including adjusting which manufacturing cells are active and when. The optimization algorithm considers energy consumption as one of multiple criteria, balancing throughput improvement against energy usage by selecting sequences that minimize unnecessary machine activation and optimize resource utilization patterns.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple manufacturing cells are coordinated centrally, then flexibility in operator interactions increases, but system complexity increases

Engineering Contradiction:
Improveflexibility in operator interactionsVSAvoidcentral coordination system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The central optimization system serves multiple functions simultaneously: it coordinates production sequences, monitors machine status, evaluates workloads, manages operator interactions, and optimizes resource allocation. This multi-functional approach consolidates what would otherwise require separate systems into a single universal coordination platform, managing complexity through integration while maximizing flexibility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Manufacturing precision

If production parameters are continuously monitored and updated, then manufacturing precision improves, but data processing requirements increase

Engineering Contradiction:
Improveproduction parameter accuracyVSAvoiddata processing load
Core Design Contradiction:
Manufacturing precisionVSLoss of information

Solution Approach 1:

The system extracts only the critical production parameters needed for optimization decisions from the full set of available data. Rather than processing all possible information, the optimization algorithm identifies and utilizes key parameters such as machine status, workload, and capability data, filtering out redundant information to maintain precision while managing data processing requirements efficiently.

Inventive Principle:
Principle #2Taking out (Extraction)
