Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed manipulation gain is set before product shipment, then the work machine can be operated with a general-purpose setting, but the manipulation gain cannot be adjusted to match individual operator skill levels and work contents
Solution Approach 1:
The system automatically calculates and updates manipulation gain based on detected operation frequency, eliminating the need for manual setting by operators. The work machine itself performs the optimization by monitoring its own usage patterns and adjusting parameters accordingly, resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The manipulation gain parameter is dynamically changed based on operation frequency data. The system transitions from a fixed parameter to a variable parameter that automatically adjusts according to detected usage patterns, enabling adaptability without requiring complex manual configuration systems.
2Productivity
If manipulation gain is arbitrarily set by operators, then individual preferences can be accommodated, but optimal settings for skill level and work contents cannot be determined
Solution Approach 1:
The system implements feedback by detecting operation frequency and using this information to automatically update manipulation gain. This closed-loop approach ensures that the system learns from actual usage patterns and continuously optimizes performance, improving productivity while capturing valuable operational information.
Solution Approach 2:
The system performs preliminary analysis of operation frequency patterns to determine optimal manipulation gain settings before making adjustments. By pre-calculating the relationship between operation frequency and optimal gain values, the system can quickly adapt to different operators and work contents without trial-and-error adjustments.
3Ease of operation
If a general-purpose manipulation gain is used for all operators, then device complexity is minimized, but working efficiency cannot be optimized for individual operators
Solution Approach 1:
The work machine automatically optimizes its own manipulation gain without requiring operator intervention or complex setting procedures. This self-service approach maintains ease of operation while significantly improving working efficiency through automatic adaptation to individual operators and work contents.
Solution Approach 2:
The system replaces manual manipulation gain setting with an automated computational system that detects operation frequency and calculates optimal gain values. This substitution eliminates the need for complex manual configuration while enabling personalized optimization for each operator and work scenario.
