Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If the battery stores more energy to extend operation time, then the device capacity increases, but the device weight and volume increase

Engineering Contradiction:
Improveoperation timeVSAvoiddevice weight
Core Design Contradiction:
Duration of action of moving objectVSWeight of moving object

Solution Approach 1:

The patent implements dynamic power management that continuously monitors battery state of charge, power consumption rates, and usage patterns to dynamically adjust power output and provide accurate time-to-empty predictions. This allows the device to optimize performance based on real-time conditions without requiring excessive battery capacity margins

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback mechanisms that track actual power consumption versus predicted consumption, continuously refining estimates of remaining operation time. This feedback loop enables the device to provide accurate runtime information without needing oversized batteries, as users can trust the predicted duration based on actual usage patterns

Inventive Principle:
Principle #23Feedback

2Loss of information

If the device provides accurate time-to-empty estimates, then user energy management improves, but the computational complexity increases

Engineering Contradiction:
Improveenergy management informationVSAvoidcomputational complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent applies simplified algorithms that focus on the most significant factors affecting battery discharge (current draw, battery voltage, temperature) rather than attempting to model all possible variables. This partial action approach provides sufficiently accurate predictions without requiring complex computational models

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system dynamically adjusts calculation parameters based on operating conditions, using different estimation methods for different states (e.g., heavy load vs. light load, different temperature ranges). This allows accurate predictions across varying conditions while keeping the computational burden manageable through context-aware parameter selection

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple power sources are used simultaneously, then energy supply flexibility increases, but the difficulty of managing energy flow increases

Engineering Contradiction:
Improveenergy supply flexibilityVSAvoidenergy flow management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal power management architecture that handles multiple power sources (battery, solar panels, AC mains, DC inputs) through a single integrated control system. This multi-functional approach consolidates what could be multiple separate management systems into one unified controller that automatically selects and manages the optimal power source combination

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

Solution Approach 2:

The system automatically monitors available power sources, their output capabilities, and current consumption patterns to self-manage power distribution without user intervention. The controller autonomously determines when to charge the battery, when to draw from external sources, and how to allocate power to different outputs, reducing the perceived complexity for users

Inventive Principle:
Principle #25Self-service
