Solution Overview

Problem

Existing methods for positioning edge elements on window or door leaves lack precision, often resulting in incorrect or crooked placement after adhesive bonding due to the absence of defined fixed points during assembly.

Innovation Solution

An auxiliary assembly tool that can be temporarily attached to the edge element, allowing it to be precisely positioned on the pane before adhesive bonding, with support legs ensuring accurate alignment and removable without additional tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the edge element is inserted into the free space without defined fixed points, then the assembly process is simple, but the positioning precision deteriorates resulting in incorrect or crooked placement after adhesive bonding

Engineering Contradiction:
Improveassembly simplicityVSAvoidpositioning precision
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent introduces an auxiliary assembly tool as an intermediary device between the edge element and the pane. This tool includes support legs that temporarily contact the pane to define the correct position of the edge element during assembly. After adhesive bonding, the auxiliary tool is removed. This mediator enables precise positioning without requiring permanent fixed points in the final structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The auxiliary assembly tool is attached to the edge element before assembly to preliminarily establish the correct positioning. The support legs of the auxiliary tool contact the pane in advance to define the assembly position, ensuring the edge element is correctly positioned before adhesive bonding occurs. This preliminary positioning action prevents incorrect placement after bonding.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If support legs are added to define the assembly position, then the positioning precision improves, but the device complexity increases due to additional components

Engineering Contradiction:
Improvepositioning precisionVSAvoidassembly tool complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent extracts the positioning function from the permanent structure by using a separate, removable auxiliary assembly tool with support legs. These support legs are only present during the assembly process to define position, then are removed along with the auxiliary tool. This extraction allows positioning without adding permanent complexity to the final structure.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The auxiliary assembly tool, including its support legs, is a temporary component that is discarded after serving its positioning purpose. The tool is attached to the edge element, used to establish correct positioning via support leg contact with the pane, then removed after adhesive bonding. This temporary use of additional components achieves precision without permanent complexity.

Inventive Principle:
Principle #34Discarding and recovering

3Manufacturing precision

If the auxiliary assembly tool requires additional tools for fixation, then the positioning precision improves, but the ease of operation deteriorates requiring more tools and steps

Engineering Contradiction:
Improvepositioning precisionVSAvoidassembly ease
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The auxiliary assembly tool is designed to be self-fixing through a manual turning mechanism. The tool attaches to the edge element by simply turning it manually, without requiring additional tools or equipment. This self-service attachment method maintains ease of operation while providing precise positioning through the support legs during assembly.

Inventive Principle:
Principle #25Self-service

AI summary

The assembly device has edge element (16) that is connected with discs by an adhesive bond. A mounting tool (33) is detachably connected with edge element before fitting edge element to disc, such that edge element is brought to mounting position of disc. The final mounting position of edge element to disc is defined, such that mounting tool is contacted with disc. The mounting tool is removed from edge element.
