Solution Overview

Problem

Conventional roof mount installation techniques compromise the integrity of flat roofs by puncturing the roofing membrane and creating weak points in the water seal, making it difficult to weld flashing members around roof mounts without causing ripples, which can lead to attachment failure.

Innovation Solution

A removable adapter cap is used to apply force to a flashing patch around a roof mount, ensuring a tight seal and facilitating a smooth welding process by providing a contour matching the roof mount, thus maintaining the roof's integrity and creating a fluid-tight interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional roof mount installation techniques are used with fasteners and secondary flashing members, then equipment can be mounted to the roof, but the integrity of the roofing membrane is compromised and ripples occur during welding

Engineering Contradiction:
Improveequipment mounting capabilityVSAvoidroofing membrane integrity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The installation system is divided into distinct components: a base plate for mechanical attachment, a flashing member for sealing, and an adapter cap for welding support. This segmentation allows each component to perform its specific function optimally without compromising the roofing membrane

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adapter cap serves as an intermediary component between the flashing member and the welding process. It provides a stable surface for welding the flashing to the roof structure without requiring direct contact with the roofing membrane, thereby preventing membrane damage and ripple formation

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If welding is performed directly on flashing members around roof mounts, then water seal can be provided, but waves or ripples occur in the membrane material

Engineering Contradiction:
Improvewater seal integrityVSAvoidmembrane surface smoothness
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The adapter cap acts as a mediator between the welding process and the flashing member. It provides a rigid support surface that distributes welding heat and mechanical stress, preventing the membrane material from waving or rippling while maintaining the water seal

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The adapter cap is installed on the flashing member before welding begins. This preliminary action establishes a stable foundation that prevents membrane distortion during the subsequent welding process, ensuring both water seal integrity and surface smoothness

Inventive Principle:
Principle #10Preliminary action

3Strength

If fasteners are used to attach roof mounts, then mechanical connection is achieved, but puncture holes are created in the primary membrane

Engineering Contradiction:
Improvemechanical connection strengthVSAvoidmembrane puncture damage
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The fastening function is separated from the sealing function. The base plate provides mechanical attachment through fasteners, while the flashing member and adapter cap provide the water seal, eliminating the need for fasteners to penetrate the primary membrane for sealing purposes

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The harmful puncture action is extracted and isolated to the base plate installation stage, while the flashing and adapter cap system provides the seal without requiring additional membrane penetration. This separates the necessary mechanical connection from the harmful membrane damage

Inventive Principle:
Principle #2Taking out (Extraction)
