Solution Overview

Problem

The installation of window linings in buildings, especially in inclined roofs, is challenging due to the need for complex geometry adaptations based on roof inclination and wall thickness, and existing solutions do not adequately address the ease of manufacturing and use, nor do they provide a fail-safe method for correct installation.

Innovation Solution

A kit of parts comprising outer and inner end members, extent members, and side members that can be transformed from a supply condition to a mounted condition to form a trapezoidal prism shape, allowing for easy assembly and adaptation to the roof structure, including the use of panels to complete the window lining.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional panel or plate materials (plywood, gypsum, chipboard) are used for window lining members, then the material availability and ease of manufacture are improved, but the adaptability to complex roof geometries and the precision of fit are worsened

Engineering Contradiction:
Improveease of manufactureVSAvoidadaptability to roof geometry
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The window lining is divided into multiple separate members (side members, top member, bottom member) that can be individually manufactured and then assembled. This segmentation allows each member to be produced using standard materials and processes while the overall structure adapts to complex geometries through the arrangement and configuration of individual segments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The lining members are designed with adjustable and adaptable features that allow them to be configured for different roof inclinations and wall thicknesses. The members can be positioned at various angles relative to the window frame, with the top and bottom members forming angles other than 90° to accommodate different architectural requirements.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If the geometry of lining members is adapted to specific roof inclinations and wall thicknesses, then the precision of fit and appearance are improved, but the complexity of manufacturing and installation is worsened

Engineering Contradiction:
Improveprecision of fitVSAvoidcomplexity of installation
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The lining members are pre-manufactured with standardized dimensions, shapes, and connection features before installation. The side members are pre-formed with trapezoidal shapes and connection elements, and the top and bottom members are pre-configured with appropriate angles. This preliminary preparation ensures precise fit while simplifying on-site installation, as craftsmen only need to assemble pre-fabricated components rather than fabricate custom pieces.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If custom visualization and adaptation of the aperture in the inner wall is performed during installation, then the adaptability to various wall configurations is improved, but the time required for installation and the skill level needed are worsened

Engineering Contradiction:
Improveadaptability to wall configurationVSAvoidinstallation time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The kit of parts is designed as a universal solution that can accommodate various roof inclinations, wall thicknesses, and aperture configurations through standardized components. The lining members are designed to work with different window frame sizes and orientations, eliminating the need for custom visualization and adaptation during installation. The same basic kit components can be configured for diverse architectural situations.

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

4Ease of operation

If existing kit solutions are used to facilitate mounting, then the ease of operation is improved, but the reliability of correct installation and the completeness of the solution are worsened

Engineering Contradiction:
Improveease of mountingVSAvoidreliability of installation
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The complete window lining solution is divided into distinct, clearly identified components (side members, top member, bottom member) with specific functions. Each component has standardized connection features and mounting interfaces, making it easy to understand how they fit together. This segmented approach with clear component definitions ensures reliable installation while maintaining ease of operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The kit design incorporates features that provide visual and physical feedback during installation to confirm correct assembly. The standardized connection elements and pre-configured geometries ensure that components fit together in the correct orientation, providing immediate feedback if installation is attempted incorrectly. This feedback mechanism increases reliability while maintaining ease of operation.

Inventive Principle:
Principle #23Feedback
