Solution Overview

Problem

Existing gantry structures for finishing and outfitting building openings require significant dimensions and thick external insulating cladding, necessitating installation on the external face of buildings, which can disturb residents and are not adaptable to varying cladding thicknesses.

Innovation Solution

A gantry structure comprising thermally insulating base, lateral, and upper transverse elements that project from the external cladding, allowing integration into the building face regardless of cladding thickness, with a slanting connecting portion for rainwater drainage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If the gantry structure uses thick mats of thermally insulating material to achieve thermal insulation, then thermal insulation performance is improved, but the dimensions of the gantry structure become significant

Engineering Contradiction:
Improvethermal insulation performanceVSAvoiddimensions of gantry structure
Core Design Contradiction:
Loss of energyVSLength of stationary object

Solution Approach 1:

The patent embeds the gantry structure within the thickness of the external insulating cladding rather than adding it externally. The base transverse element, lateral uprights, and upper transverse element are configured to be mounted within the cladding layer, nesting the structural components inside the existing insulation thickness to avoid increasing overall dimensions.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent transitions from a three-dimensional external protruding structure to a two-dimensional integration within the cladding layer. By mounting the gantry structure within the plane of the cladding rather than extending outward, the design achieves thermal insulation without significantly increasing the building's external dimensions.

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

2Ease of operation

If the gantry structure is installed on the external face of the building, then installation can be carried out without accessing inner spaces, but the external insulating cladding requires great and predetermined thickness

Engineering Contradiction:
Improveinstallation accessibilityVSAvoidthickness of external insulating cladding
Core Design Contradiction:
Ease of operationVSLength of stationary object

Solution Approach 1:

The patent makes the gantry structure adaptable to varying cladding thicknesses through adjustable mounting configurations. The base transverse element and lateral uprights can be positioned at different depths within the cladding layer, allowing the structure to accommodate varying insulation thicknesses while maintaining external accessibility during installation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent allows the gantry structure to adapt to different cladding thickness parameters. The mounting elements can be positioned at variable distances from the building facade, enabling the structure to fit within different cladding thickness ranges without requiring a predetermined minimum thickness.

Inventive Principle:
Principle #35Parameter changes

3Shape

If the gantry structure projects from the external insulating cladding, then integration into the building face is achieved, but rainwater drainage becomes problematic

Engineering Contradiction:
Improveintegration into building faceVSAvoidrainwater drainage
Core Design Contradiction:
ShapeVSObject-affected harmful factors

Solution Approach 1:

The patent incorporates a slanting connecting portion with a curved or angled surface that directs rainwater away from the gantry structure. The transverse wall includes a sloped surface that uses gravity to channel water toward drainage openings, preventing water accumulation on the projecting structure.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The patent extracts the drainage function from the main structural body by incorporating separate drainage openings in the transverse wall. These openings allow rainwater to exit the housing seat through the slanting connecting portion, separating the structural support function from the drainage function.

Inventive Principle:
Principle #2Taking out (Extraction)
