Solution Overview

Problem

Existing power distribution systems for apartment complexes with solar panels face inefficiencies and high costs due to undercapacity or overcapacity issues, making it impractical to share energy effectively across geographically spaced-apart groups of consumers.

Innovation Solution

A system comprising two power distributing devices connected in parallel, with a switching and control unit that allows power from one source to be distributed to consuming units of another group, optimizing energy distribution based on demand and supply ratios, and utilizing energy storage to minimize feedback to the grid.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If power distributing devices supply power to a fixed predetermined group of power consuming units, then the system structure is simple and easy to implement, but the capacity utilization is low due to undercapacity or overcapacity issues

Engineering Contradiction:
Improvesystem implementation easeVSAvoidcapacity utilization
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The power distributing device is designed to serve multiple functions: it can supply power to its assigned group of power consuming units, but also to other groups when they have power demand. This multi-functionality allows the device to adapt to varying power needs across different groups, improving capacity utilization while maintaining a relatively simple system structure.

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

Solution Approach 2:

The system dynamically adjusts power distribution based on real-time power portions produced by power sources and actual power demands of different groups. The power distributing device can flexibly reallocate power capacity between groups, transitioning from a static fixed-assignment model to a dynamic adaptive model that optimizes capacity utilization.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If power is distributed only to a fixed group of power consuming units, then the distribution control is simple, but power demand cannot be satisfied when the assigned power source has undercapacity

Engineering Contradiction:
Improvedistribution control complexityVSAvoidpower supply reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

A control unit acts as an intermediary between power sources and power consuming units. It receives information about power portions produced by power sources and power demands from various groups, then intelligently decides how to allocate power. This intermediary layer adds minimal complexity while significantly improving power supply reliability by enabling flexible reallocation to meet demand.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback mechanisms where the control unit continuously monitors power production from sources and power demand from consuming units. Based on this feedback, the control unit adjusts power distribution in real-time, ensuring that power supply reliability is maintained even when capacity conditions change, while keeping control complexity manageable through automated decision-making.

Inventive Principle:
Principle #23Feedback

3Device complexity

If solar energy is fed to a collective meter, then the energy system is simplified, but the financial balance is unfavorable due to legislation requirements

Engineering Contradiction:
Improveenergy system complexityVSAvoidfinancial balance
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The system segments power distribution into separate channels for different groups of power consuming units. Each group can receive power directly from power sources through dedicated distributing devices, rather than consolidating all power through a single collective meter. This segmentation enables independent accounting and settlement for each group, satisfying legislative requirements for direct feeding while maintaining system simplicity through modular architecture.

Inventive Principle:
Principle #1Segmentation
