Solution Overview

Problem

Existing window and door glazing rebate bonding technologies face challenges such as complex and expensive production of elastomeric webs, time-consuming installation preparation, and adhesive contamination during the assembly process, which hinder efficient glazing block alignment and static load distribution.

Innovation Solution

A glazing rebate element made partially or fully from a resilient material forms an adhesive reservoir upon assembly, preventing excess adhesive from reaching the glazing bead and allowing for easy insertion of glazing blocks without hindering the assembly process, while maintaining a clean frame surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If elastomeric webs or lips are used to limit adhesive introduction, then adhesive layer extension is controlled, but production complexity and cost increase

Engineering Contradiction:
Improveadhesive layer extension controlVSAvoidproduction complexity of webs or lips
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent extracts the adhesive-limiting function from complex elastomeric webs and implements it through the geometric design of the glazing rebate element itself. The rebate element's shape and positioning naturally limit adhesive extension without requiring separate elastomeric components, thereby reducing production complexity while maintaining manufacturing precision.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The glazing rebate element serves multiple functions: it provides mechanical support for the glazing, defines the adhesive application area through its geometry, and acts as a stop for adhesive extension. This multi-functionality eliminates the need for separate elastomeric webs, reducing device complexity while maintaining precise adhesive control.

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

2Manufacturing precision

If webs or lips are produced from elastomeric material, then adhesive introduction is limited, but production cost increases

Engineering Contradiction:
Improveadhesive introduction controlVSAvoidproduction cost
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent changes the material parameter from elastomeric material to standard rigid or semi-rigid materials used in glazing rebate elements. This parameter change maintains the adhesive introduction control function through geometric design while significantly reducing production cost by using conventional materials and manufacturing processes.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If adhesive is filled before glazing block installation, then adhesive reservoir is ready, but alignment process is hindered

Engineering Contradiction:
Improveadhesive reservoir preparationVSAvoidglazing block alignment
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent implements preliminary action by pre-filling the adhesive reservoir through the filling opening before glazing block installation. The filling opening is designed to be accessible and allow easy filling, while the subsequent closure of the opening prevents adhesive leakage during the alignment process, thus maintaining both productivity and ease of operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The filling opening serves as an intermediary element that allows adhesive to be introduced into the reservoir before the glazing blocks are installed. This intermediary structure enables the adhesive reservoir to be prepared in advance without interfering with the subsequent alignment process, as the opening can be closed or sealed after filling.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If adhesive reservoir is filled after glazing block installation, then alignment is easier, but adhesive contamination occurs

Engineering Contradiction:
Improveglazing block alignmentVSAvoidadhesive contamination
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent applies preliminary action by filling the adhesive reservoir before glazing block installation. The filling opening is designed to facilitate easy filling, and after filling, the opening is closed or sealed, preventing adhesive from leaking out during the alignment process. This eliminates adhesive contamination while maintaining ease of operation.

Inventive Principle:
Principle #10Preliminary action

5Reliability

If full-circumferential bonding is used, then glazing is securely bonded, but installation time increases

Engineering Contradiction:
Improveglazing bonding securityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent segments the bonding process by using a controlled adhesive application area defined by the glazing rebate element geometry. Instead of requiring full-circumferential bonding, the adhesive is applied only in specific areas where it is needed, reducing installation time while maintaining sufficient bonding security through strategic placement.

Inventive Principle:
Principle #1Segmentation
