Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If ventilation ducts are moulded into a sandwich-type wall element at the element factory, then the mutual position and insulation of the ducts are ensured, but the installation is not flexible for different insulation thicknesses at construction sites

Engineering Contradiction:

Improvemutual position and insulation of ductsVSAvoidadaptability to different insulation thicknesses

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The pass-through piece is divided into separate components: the insulation adapter with adjustable duct positioning mechanism, allowing the ducts to be positioned at different depths while maintaining proper spacing and insulation. This segmentation enables customization for different wall thicknesses while preserving manufacturing precision through the locking mechanism.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The duct positioning system incorporates adjustable and lockable mechanisms that allow the ducts to be dynamically positioned at various depths within the insulation layer. This dynamic capability enables the same pass-through piece to adapt to different insulation thicknesses while maintaining secure positioning through the locking devices.

Inventive Principle:

Principle #15Dynamics

2Ease of manufacture

If the depth of ducts is fixed in the insulation adapter, then manufacturing is simplified, but the installation cannot be adjusted to match different receiving structure depths

Engineering Contradiction:

Improvesimplicity of insulation adapter manufacturingVSAvoidadjustability during installation

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The insulation adapter incorporates adjustable duct positioning mechanisms with locking devices that allow installers to set duct depths according to the specific receiving structure. The adjustable design maintains manufacturing simplicity through standardized components while enabling field customization for different installation requirements.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If ventilation ducts are installed at the building site in wooden houses, then installation flexibility is improved, but achieving accurate spacing between parallel ducts becomes challenging

Engineering Contradiction:

Improveinstallation flexibility at building siteVSAvoidspacing accuracy between parallel ducts

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The pass-through piece is designed as a segmented assembly with separate insulation adapter and duct components, allowing flexible installation at the building site while maintaining precise spacing through the structured design of the adapter that guides and positions multiple ducts at predetermined intervals.

Inventive Principle:

Principle #1Segmentation

4Adaptability or versatility

If insulation thickness varies at different construction sites, then customization for each site is needed, but producing multiple pass-through sizes increases waste

Engineering Contradiction:

Improvecustomization for different insulation thicknessesVSAvoidwaste from producing multiple sizes

Core Design Contradiction:

Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The insulation adapter is designed as a universal component that can accommodate ducts of various depths and configurations through its adjustable positioning mechanism. This multi-functional design allows a single standard-sized pass-through piece to serve multiple insulation thickness requirements, eliminating the need to produce and stock multiple specialized sizes, thereby reducing material waste.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A novel leadthrough kit (100) and a method for producing pass through for ventilation ducts in a receiving structure are disclosed. The leadthrough kit includes a first duct (120), a second duct (130) and an insulation adapter (110). The insulation adapter is rectangular in shape and contains a first through hole (112) for receiving the first duct (120) and a second through hole (113) for receiving a second duct (130) parallel with the first duct (120). The axial position of the first and second duct (120, 130) can be adjusted in relation to the insulation adapter (110).
