Solution Overview

Problem

Existing methods for assembling and disassembling roof window sash frames are risky and prone to damage due to the need for manual handling of heavy components, which can lead to injury and incorrect installation.

Innovation Solution

A kit with a support element that temporarily fastens to the sash frame, allowing it to be suspended and positioned relative to the window frame without bearing its weight, facilitating safe and precise hinge assembly and disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If manual handling methods are used to install heavy sash frames, then installation can be performed without additional equipment, but the risk of injury and damage to components increases significantly

Engineering Contradiction:
Improveinstallation simplicityVSAvoidsafety and damage prevention
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent introduces temporary support elements as intermediary devices between the sash frame and the installers. These support elements temporarily bear the weight of the heavy sash frame during installation and positioning, eliminating the need for installers to manually support the weight while ensuring safe and precise handling. The support elements are removed after the sash frame is securely mounted to the window frame.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If plastering clips are used to pre-fix the sash frame, then the sash can be positioned relative to the frame, but the clips are at risk of damage as they are not designed to support the entire weight

Engineering Contradiction:
Improvepositioning accuracyVSAvoidclip load capacity
Core Design Contradiction:
Manufacturing precisionVSStrength

Solution Approach 1:

The patent introduces temporary support elements as intermediary devices between the sash frame and the installers. These support elements temporarily bear the weight of the heavy sash frame during installation and positioning, eliminating the need for installers to manually support the weight while ensuring safe and precise handling. The support elements are removed after the sash frame is securely mounted to the window frame.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The support elements are installed on the sash frame before the actual mounting operation begins. This preliminary action ensures that the sash frame is already supported and positioned correctly before any weight-bearing operations commence, preventing damage to the plastering clips and ensuring accurate positioning from the start.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If multiple people are used to hold and guide the sash frame, then the sash can be maneuvered into position, but the complexity of coordination increases and safety risks remain

Engineering Contradiction:
Improvehandling capabilityVSAvoidinstallation procedure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces temporary support elements as intermediary devices between the sash frame and the installers. These support elements temporarily bear the weight of the heavy sash frame during installation and positioning, eliminating the need for installers to manually support the weight while ensuring safe and precise handling. The support elements are removed after the sash frame is securely mounted to the window frame.
