Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If data throughput rate is increased to improve transfer speed, then productivity is improved, but use of energy by moving object increases causing battery depletion

Engineering Contradiction:

Improvedata transfer speedVSAvoidbattery consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic throughput adjustment by continuously monitoring battery charge level and transferring data at optimized rates. The system transitions from static fixed throughput to dynamic adaptive throughput that automatically adjusts based on real-time battery status, resolving the contradiction between transfer speed and energy consumption

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the throughput parameter dynamically based on battery charge level. When charge level drops below thresholds, the throughput parameter is automatically reduced to conserve energy, ensuring complete data transfer while maintaining sufficient battery charge for emergency use

Inventive Principle:

Principle #35Parameter changes

2Loss of time

If data transfer is completed quickly to improve productivity, then loss of time is reduced, but loss of energy increases due to higher power consumption

Engineering Contradiction:

Improvedata transfer timeVSAvoidbattery charge depletion

Core Design Contradiction:

Loss of timeVSLoss of energy

Solution Approach 1:

The patent applies parameter changes by adjusting throughput rate based on battery charge level thresholds. The system accepts variable transfer times as a necessary trade-off to ensure energy conservation, automatically reducing throughput when charge levels drop to maintain sufficient battery for emergency situations

Inventive Principle:
