Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If press line simulation focuses only on productivity optimization, then manufacturing efficiency is improved, but energy consumption information is not available for carbon neutrality goals

Engineering Contradiction:

Improvemanufacturing efficiencyVSAvoidenergy consumption information

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The simulation device is enhanced to perform multiple functions: it not only optimizes productivity by generating press line motions and detecting interference (原有功能), but also calculates power consumption information (新增功能). This multi-functional capability allows the same simulation system to address both productivity optimization and energy consumption analysis, eliminating the need for separate simulation systems and enabling comprehensive press line optimization.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If press line motion is optimized for productivity, then output increases, but energy consumption may increase without being able to confirm it

Engineering Contradiction:

ImproveoutputVSAvoidenergy consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The simulation device implements a feedback mechanism by calculating power consumption information based on the generated press line motion and providing this information back to operators. This feedback loop enables operators to adjust press line motions not only for productivity optimization but also for energy consumption optimization, allowing iterative improvement of both output and energy efficiency.

Inventive Principle:

Principle #23Feedback

3Reliability

If conventional press line simulation is used, then interference between press device and feeder device is avoided, but energy consumption cannot be confirmed or optimized

Engineering Contradiction:

Improveinterference avoidanceVSAvoidpower consumption information

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The invention merges the interference detection function with the power consumption calculation function into a single simulation device. The simulation device generates press line motions, detects interference between press devices and feeder devices, and simultaneously calculates power consumption information based on the generated motions. This integration allows operators to optimize press line operations for both reliability and energy efficiency simultaneously.

AI summary

The simulation program is a simulation program that simulates a motion of a press line including press devices (1P to 5P) that press a workpiece (W) and includes a step (S1) and steps (S2 to S4). In step (S1), the motion of the press line (1) is generated. In steps (S2 to S4), information regarding power consumption of the press line (1) is calculated based on the motion of the press line (1).
