Solution Overview

Problem

Thermoplastic roofing systems lack aesthetic appeal and functional versatility while being easy to install, with uniform appearances that do not meet architectural or design requirements.

Innovation Solution

Composite roofing strips with a longitudinally extending body and an insert that can be adjusted to match a roofing membrane's contour, allowing for customizable profiles and easy attachment via connection members, made from thermoplastic and metallic materials for flexibility and rigidity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If thermoplastic roofing systems use uniform structures for ease of installation, then ease of installation is improved, but aesthetic appeal deteriorates

Engineering Contradiction:
Improveease of installationVSAvoidaesthetic appeal
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The roofing system is divided into modular panels with standardized connection mechanisms, allowing uniform installation procedures while each panel can have varied aesthetic profiles. The segmentation enables consistent assembly processes while maintaining design flexibility at the panel level.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The roofing panels incorporate adjustable profile mechanisms that allow the shape to be modified after installation. This dynamic capability enables the system to maintain uniform installation procedures while achieving varied aesthetic appearances through post-installation profile adjustments.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If thermoplastic roofing systems use simple uniform structures, then ease of installation is improved, but functional versatility deteriorates

Engineering Contradiction:
Improveease of installationVSAvoidfunctional versatility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The roofing panels are designed with universal connection systems that can accommodate multiple installation configurations and functional requirements. The standardized mounting mechanisms work across different panel types and roof configurations, providing both ease of installation and functional adaptability.

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

Solution Approach 2:

The system allows modification of key parameters such as panel profiles, orientations, and connection methods after initial installation. This parameter flexibility enables the same basic structure to serve multiple functions and adapt to different requirements without compromising installation simplicity.

Inventive Principle:
Principle #35Parameter changes

3Stability of the object's composition

If roofing strips are made rigid to maintain shape, then shape stability is improved, but ease of adjustment deteriorates

Engineering Contradiction:
Improveshape stabilityVSAvoidease of adjustment
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The roofing panels are pre-formed with approximate profiles during manufacturing, providing initial shape stability. This preliminary shaping reduces the adjustment effort required during installation while maintaining the final shape stability through the rigid panel structure.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Adjustable connection elements serve as intermediaries between the rigid panels and the mounting structure. These intermediaries allow for profile adjustments during installation while the rigid panels themselves maintain their shape stability once positioned.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Embodiments of the invention provide composite roofing strips that may be attached to a roofing membrane for aesthetic and/or functional purposes and method of attaching the same. According to one embodiment, a composite roofing strip may include a longitudinally extending body having a base and a lateral member extending from the base, and may also include an insert extending partially or fully along the body and coupled therewith. The insert may be formable so as to allow the composite roofing strip to be adjusted to have a desired profile and to maintain the desired profile of the composite roofing strip post adjustment.
