Solution Overview

Problem

Portable air conditioners face issues with unstable anchoring and inefficiency due to unwanted exchange between internal and external environments when using existing support members for air pipes, especially in windows with sliding motions, leading to potential damage and energy waste.

Innovation Solution

A modular support member with a slit for the air pipe and clamping mechanisms that stabilize the position of the pipe between the window frame and mobile parts, using sliding modules with stabilizing members that integrate with window guides, allowing continuous adjustment without requiring carpentry interventions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the window is kept open to accommodate the air outlet pipe, then the air pipe can be positioned to extract hot air outside, but unwanted exchange between internal and external space occurs allowing dust, pollen, insects, and water to enter

Engineering Contradiction:
Improveair pipe positioningVSAvoidcontamination and unwanted air exchange
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The support member is divided into multiple segments: a first element with a slit for the air pipe, a second element that slides relative to the first, and a third element that clamps the assembly to the window frame. This segmentation allows the air pipe to be isolated within the slit while the support structure interfaces with the window, preventing direct contact between the pipe and window opening.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support member acts as an intermediary device between the air pipe and the window frame. It provides a stable mounting structure that secures the air pipe in position while blocking the window opening, thereby mediating between the need for pipe access and the need to prevent unwanted air exchange and contamination.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If existing support members are used, then the air pipe can be supported, but stable anchoring is not achieved allowing the pipe to move and be damaged due to window closing or drafts

Engineering Contradiction:
Improveair pipe supportVSAvoidpipe positioning stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The support member incorporates a sliding mechanism where the second element can move relative to the first element along a sliding surface. This dynamic adjustment capability allows the support structure to adapt to different window positions and secure the air pipe firmly, preventing movement and damage while maintaining ease of installation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention adds a sliding dimension to the support structure, transforming it from a static rigid support to a dynamically adjustable one. The second element slides along the first element to accommodate window movement, providing stability in multiple dimensions and preventing pipe displacement caused by window closing or air drafts.

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

3Ease of manufacture

If a fixed support member is used, then installation is simple, but adaptability to windows of different sizes and types is limited

Engineering Contradiction:
Improvesupport member fabricationVSAvoidwindow compatibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The support member features a sliding mechanism that allows continuous adjustment of the distance between elements, enabling adaptation to windows of various sizes. The second element slides along the first element, providing flexibility to accommodate different window dimensions and types while maintaining a relatively simple fixed-structure design.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The support member is designed as a universal solution that can be applied to various window types and sizes. The sliding mechanism and adjustable clamping system allow the same basic structure to adapt to different installation scenarios, making it a multi-functional support device that works across diverse window configurations.

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

AI summary

A support member for air-carrying pipes of portable air conditioners which can be applied to windows (W), comprises a first module (12) provided with a slit (16) made to accommodate the air pipe and at least one second module (14) made to be coaxially sliding on the first module (12). The second module (14) is continuously mobile with respect to said first module (12) to make the length of the support member (10) modifiable.
