Solution Overview

Problem

The increasing number of external devices on recreational vehicles, such as mobile homes, leads to complexity due to the multitude of cables and control interfaces required, complicating the overall system.

Innovation Solution

An air conditioning unit with integrated connection ports on its outer cover, allowing easy access for external devices, serving as a connection hub and reducing system complexity by enabling electric and electronic connections, control, and data transfer, while incorporating wireless connectivity and various port types for direct and alternating current, solar panels, antennas, cameras, and lights.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple external devices are installed on the recreational vehicle, then the functionality and comfort are improved, but the system complexity increases due to the increasing number of cables and control interfaces

Engineering Contradiction:
ImprovefunctionalityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple connection functions (power supply, data transfer, control interfaces) into a single integrated air conditioning unit. This allows multiple external devices to connect through one centralized hub rather than requiring separate connections for each device, thereby maintaining versatility while reducing system complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The air conditioning unit is designed to serve multiple purposes: it provides cooling functionality while simultaneously acting as a connection hub for various external devices. The unit includes multiple connection ports that can accommodate different device types (solar panels, antennas, cameras, lights), making it a universal interface that handles diverse connectivity needs through a single device

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

2Ease of operation

If connection ports are integrated into the air conditioning unit, then the ease of operation is improved by providing accessible connection points, but the device complexity increases due to additional components

Engineering Contradiction:
ImproveaccessibilityVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The air conditioning unit incorporates multiple types of connection ports (power sockets, data ports, control interfaces) within its structure, enabling it to handle various connection needs through a single device. This multi-functional design provides accessibility for different device types without requiring separate connection mechanisms for each function

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

Solution Approach 2:

The air conditioning unit's housing and outer cover are designed to provide self-contained protection and organization for all connection ports and components. The integrated design allows the unit to manage its own complexity internally while presenting a simplified, user-friendly interface externally through accessible connection points

Inventive Principle:
Principle #25Self-service
