Solution Overview

Problem

Portable power stations need to be recharged using non-renewable energy sources, and there is a lack of efficient systems for indoor charging from solar panels.

Innovation Solution

A through-wall power station outlet kit that includes an exterior power inlet box connected to an interior receptacle box via a conduit, allowing for parallel or series connections and featuring an electronic display for energy transfer monitoring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If portable power stations are recharged using common house receptacles, then recharging is convenient and simple, but the power source is typically not renewable (solar)

Engineering Contradiction:
Improverenewable energy capabilityVSAvoidrecharging convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces an intermediary through-wall power transfer system that includes an exterior power inlet box with solar panel connections and an interior power outlet box with receptacles. This intermediary system enables renewable energy transfer through the wall structure, combining the benefits of solar power with convenient indoor receptacle access without requiring extension cords or complex external connections.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If solar panels are installed outside to charge portable power stations, then renewable energy usage is achieved, but extension cords are required which reduce convenience and safety

Engineering Contradiction:
Improvesolar power integrationVSAvoidcharging convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The wall-mounted power transfer system acts as an intermediary that eliminates the need for extension cords. The exterior power inlet box receives solar panel connections outside the building, and the interior power outlet box provides standardized receptacles inside, creating a safe and convenient integrated system that transfers power through the wall structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent utilizes the wall structure as a third dimension to transfer power from exterior to interior. Instead of using extension cords that extend power laterally across the ground surface, the system routes power vertically through the wall, utilizing the building envelope as a conduit for power transfer.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If portable power stations are charged indoors without a dedicated system, then simplicity is maintained, but efficient solar power transfer is not achieved

Engineering Contradiction:
Improvecharging efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The power transfer system is segmented into distinct functional components: an exterior power inlet box for solar panel connections, interior power outlet boxes with receptacles, and wall-mounted conduit systems. This segmentation allows for efficient solar power transfer while maintaining manageable system complexity through modular, pre-assembled units that can be installed independently.

Inventive Principle:
Principle #1Segmentation

AI summary

A through-wall power station outlet kit may include a power inlet box located in an exterior environment and protected with a bubble cover. The power inlet box may include power generation terminals configured for electrical attachment to a power generation device such as an inverter, a generator, and solar panels. On the interior side, a receptacle box may be used with a plurality of power station terminals for electrical connection to a portable power station. A conduit may join the exterior power inlet box to the interior receptacle box such that the conduit is installed within a wall between the exterior and the interior.
