Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

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

Engineering Contradiction:

Improvedata transfer speedVSAvoidbattery charge consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic throughput adjustment where the system continuously monitors battery charge level and data payload characteristics, then adaptively modifies the data transfer rate in real-time. This allows the throughput to be high when battery charge is sufficient and low when battery charge is depleted, resolving the contradiction between transfer speed and energy consumption

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the throughput parameter based on battery charge level and data payload size. By dynamically adjusting this key parameter, the system optimizes the balance between transfer productivity and energy consumption, ensuring faster transfers when energy is abundant and slower transfers when energy is limited

Inventive Principle:

Principle #35Parameter changes

2Productivity

If data transfer continues until completion, then productivity is improved, but duration of action increases causing extended battery depletion

Engineering Contradiction:

Improvedata transfer completionVSAvoidbattery charge duration

Core Design Contradiction:

ProductivityVSDuration of action of moving object

Solution Approach 1:

The patent implements a feedback mechanism where the system continuously monitors battery charge level during data transfer and adjusts throughput accordingly. This closed-loop control ensures that transfer duration is optimized based on real-time energy availability, preventing excessive battery depletion while still completing transfers when energy permits

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system dynamically adjusts transfer duration by modulating throughput in response to battery charge feedback. This creates an adaptive transfer process that completes data transmission efficiently when energy is available while automatically extending or truncating transfer duration based on real-time energy constraints

Inventive Principle:

Principle #15Dynamics

3Use of energy by moving object

If throughput is reduced to conserve battery, then use of energy is improved, but productivity decreases causing slower data transfer

Engineering Contradiction:

Improvebattery charge conservationVSAvoiddata transfer rate

Core Design Contradiction:

Use of energy by moving objectVSProductivity

Solution Approach 1:

The system intelligently changes the throughput parameter based on battery charge level and data payload characteristics. When battery charge is high, throughput is increased to maximize transfer speed. When battery charge is low, throughput is reduced to conserve energy. This dynamic parameter adjustment resolves the contradiction by optimizing both energy efficiency and transfer productivity based on real-time conditions

Inventive Principle:

Principle #35Parameter changes

4Adaptability or versatility

If dynamic adjustment mechanisms are implemented, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improvethroughput optimization capabilityVSAvoidsystem structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary optimization layer that sits between the data transfer protocol and the physical transmission medium. This intermediary component monitors battery charge and data characteristics, then mediates the throughput rate. By placing this intelligence at the protocol layer rather than requiring hardware modifications, the system achieves high adaptability with minimal increase in device complexity

Inventive Principle:

Principle #24Intermediary (Mediator)
