Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional static system configurations are used for power transfer, then system design is simplified with known source and load configurations, but power transfer efficiency is reduced due to inability to adapt to varying power sources and loads

Engineering Contradiction:
Improvesystem design simplicityVSAvoidpower transfer efficiency
Core Design Contradiction:
Ease of manufactureVSLoss of energy

Solution Approach 1:

The patent applies dynamics by transforming the static power transfer system into a dynamic one through the use of switching circuitry that continuously adjusts the connection configuration between power sources and loads. The system detects power changes and dynamically reconfigures which power sources are connected to which loads, enabling adaptation to varying power availability and load demands, thereby resolving the contradiction between design simplicity and power transfer efficiency.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements feedback through detection circuitry that continuously monitors power changes in the system. This feedback mechanism provides real-time information about power source availability and load requirements, which is then used by the switching circuitry to optimize power transfer connections. The feedback loop enables the system to maintain high power transfer efficiency by continuously adapting to changing conditions while preserving relative design simplicity through automated control.

Inventive Principle:
Principle #23Feedback

2Stability of the object's composition

If static design principles are used to regulate power output, then consistent regulated power transfer is achieved, but adaptability to varying power sources and loads is lost

Engineering Contradiction:
Improvepower transfer consistencyVSAvoidadaptability to varying sources and loads
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent resolves this contradiction by making the power transfer system dynamic rather than static. The switching circuitry continuously reconfigures connections based on detected power changes, allowing the system to adapt to varying power sources and loads while maintaining stable and efficient power transfer. This dynamic approach replaces fixed design principles with adaptive control that preserves consistency through continuous optimization.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies parameter changes by modifying the connection configuration parameters in response to detected power changes. The system changes which power sources are connected to which loads based on real-time conditions, enabling adaptability to varying sources and loads while maintaining consistent regulated power transfer through automated parameter adjustment rather than fixed design parameters.

Inventive Principle:

3Loss of energy

If impedance matching is implemented through dynamic switching, then power transfer efficiency is maximized, but device complexity increases with additional switching circuitry and detection circuitry

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The patent applies universality by designing the switching circuitry to perform multiple functions simultaneously: it manages impedance matching, optimizes power transfer connections, and responds to power changes. This multi-functional approach maximizes power transfer efficiency while minimizing the addition of separate dedicated circuits, thereby reducing overall device complexity compared to having separate circuits for each function.

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

Solution Approach 2:

The patent implements self-service through the detection circuitry that automatically monitors power changes and triggers appropriate switching actions without external intervention. The system self-regulates to maintain optimal power transfer efficiency by detecting conditions and automatically reconfiguring connections, reducing the need for complex external control mechanisms and simplifying the overall device architecture.

Inventive Principle:
Principle #25Self-service

AI summary

Apparatuses and systems enable power transfer from one or more energy sources to one or more loads. The input power from the energy sources may be unregulated, and the output power to the loads is managed. The power transfer is based on a dynamic implementation of Jacobi's Law (also known as the Maximum Power Theorem). In some embodiments, the energy sources are selectively coupled and decoupled from the power transfer circuitry. In some embodiments, the loads are selectively coupled and decoupled from the power transfer circuitry. Power transfer to the loads is dynamically controlled.
