Solution Overview

Problem

The existing methods for glazing doors are costly and time-consuming due to the need for a specially formulated jointing compound and precise operation to ensure a watertight and windproof seal, particularly when adapting wooden frames to various geometrical shapes.

Innovation Solution

A glazed door design featuring a profiled insulating layer with an L-shaped section around the aperture, allowing the insulating layer to form a direct seal with the glazing unit without the use of jointing compound, and accommodating different geometrical shapes by varying the size and shape of the openings in the outer layers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a wooden frame and jointing compound are used to seal the glazing unit, then a watertight and windproof seal can be achieved, but the manufacturing process becomes costly and time-consuming

Engineering Contradiction:
Improvesealing reliabilityVSAvoidmanufacturing efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The invention extracts and eliminates the wooden frame and jointing compound from the glazing system, replacing them with a self-sealing aperture design where the glazing unit directly interfaces with the door structure through precisely formed openings, thereby simplifying the manufacturing process while maintaining sealing reliability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The aperture openings are pre-formed in the door structure before the glazing unit is installed, with precise dimensions and positions that enable direct sealing contact, eliminating the need for on-site frame assembly and compound application

Inventive Principle:
Principle #10Preliminary action

2Strength

If a wooden frame is used to accommodate the glazing unit, then structural support is provided, but adapting to different geometrical shapes becomes difficult

Engineering Contradiction:
Improvestructural supportVSAvoidgeometrical adaptability
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The aperture design serves multiple functions: it provides structural support through the door structure itself, enables sealing through precise dimensional matching, and accommodates various geometrical shapes of glazing units by forming corresponding opening shapes directly in the door layers

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

Solution Approach 2:

The aperture openings are locally adapted to match the specific geometrical shape of each glazing unit, with the first and second outer layers and insulating layer forming openings that correspond to the unique shape requirements of the glazing unit while maintaining overall structural integrity

Inventive Principle:
Principle #3Local quality

3Reliability

If jointing compound is used to secure the glazing unit, then a watertight seal is achieved, but precise application and monitoring are required

Engineering Contradiction:
Improvewatertight sealVSAvoidapplication complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The aperture design enables the glazing unit to self-seal through direct contact with the door structure at precisely formed interfaces, eliminating the need for external jointing compound application and the complex monitoring processes that would be required to ensure proper sealing

Inventive Principle:
Principle #25Self-service

AI summary

The present invention relates to a glazed door (1) comprising an insulating layer (4) and a glazing unit (5) set in an aperture (6) in the door (1 ). The invention is characterized in that the insulating layer (1) around the aperture (6) comprises a profiled section (14) designed to contain the glazing unit (5) in such a way that the profiled section (14) and the glazing unit (5) bear against one another and form a sealing bond.
