Solution Overview

Problem

Conventional fenestration systems face challenges in routing and integrating cables and wiring during installation, particularly due to limited access in assembled profiles and the risk of short circuits and water leakage, which complicates the incorporation of smart systems and increases installation time.

Innovation Solution

A fenestration profile with a retention mechanism, such as a thermal break, that houses communication lines within a cavity, allowing pre-integration of cables during manufacturing, eliminating the need for onsite cabling and reducing installation complexity while preventing water migration and short circuits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If cables are routed through profile voids during manufacturing, then cable integration is simplified and access is easier, but profile assembly complexity increases and water tightness risk increases

Engineering Contradiction:
Improvecable routing accessVSAvoidprofile assembly complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The profile is divided into separate components (first profile portion, second profile portion, and retention mechanism) that are assembled after cable routing. The retention mechanism is a separate component that can be installed independently, allowing cables to be routed through the profile void before final assembly, thus simplifying cable integration without permanently complicating the profile structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Cables are routed through the profile voids during manufacturing before the profile portions are assembled. This preliminary cable routing action allows cables to be positioned and secured within the voids while access is still available, avoiding the need for complex post-assembly cable management.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If cables are placed in profile voids, then cable routing is simplified, but water tightness deteriorates and short circuit risk increases

Engineering Contradiction:
Improvecable routingVSAvoidwater tightness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The retention mechanism acts as an intermediary component between the cable and the profile void. It provides a dedicated structure for cable support and positioning that is integrated into the profile assembly, allowing cables to be routed through the void while maintaining the integrity of the profile's water tightness system.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The retention mechanism is extracted as a separate component from the main profile structure. This allows the profile voids to maintain their original water tightness characteristics while the retention mechanism provides dedicated cable management functionality, separating the cable routing function from the structural profile.

Inventive Principle:
Principle #2Taking out (Extraction)

3Strength

If profiles are assembled before cable routing, then structural integrity is maintained, but cable access becomes difficult or impossible

Engineering Contradiction:
Improveprofile structural integrityVSAvoidcable access
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

Cable routing is performed as a preliminary action during manufacturing before the profile portions are assembled into the final structure. This timing allows easy access to the profile voids for cable installation while the profile components are still separate, and the structural integrity is established through subsequent assembly of the profile portions with the retention mechanism in place.

Inventive Principle:
Principle #10Preliminary action

4Loss of time

If cables are routed in glazing area and beading, then cable routing is possible after assembly, but space for glass packers and insulation is reduced

Engineering Contradiction:
Improveinstallation timeVSAvoidglazing area space
Core Design Contradiction:
Loss of timeVSArea of stationary object

Solution Approach 1:

The profile is segmented into distinct components with dedicated functions: the profile voids provide cable routing space, the retention mechanism provides cable support, and the glazing area provides space for glass packers and insulation. This segmentation allows each component to fulfill its primary function without encroaching on the space required by other components, avoiding the need to route cables through the limited glazing area.

Inventive Principle:
Principle #1Segmentation
