Solution Overview

Problem

Conventional fenestration system wiring methods require drilling through structural members, leading to weakened frames and unsightly wiring, and are difficult to route and trace for maintenance or replacement.

Innovation Solution

A frame profile with a corner clip and wire channel system that facilitates easy transition and securement of wires between vertical and horizontal members, using corner clips and wire clips to manage wiring efficiently and conceal it within the frame profile.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If wiring is routed through drilling structural members, then electrical connections can be established, but the frame profile strength and weather intrusion resistance are weakened

Engineering Contradiction:
Improvewiring installationVSAvoidframe profile strength
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The wiring system is segmented into modular components: corner clips with wire channels, wire clips, and gaskets. This segmentation allows wiring to be installed without drilling through structural members, thereby maintaining frame strength while enabling easy wire routing through dedicated channels and pathways.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Corner clips and wire channels act as intermediaries between different frame members and the wiring system. These intermediary components provide dedicated pathways for wires to transition between vertical and horizontal members without compromising the structural integrity of the frame profile.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Shape

If wiring is routed through interior hollows, then cables can be concealed, but routing becomes difficult due to constrictions and hidden obstacles

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidwiring installation
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

Wire channels and pathways are pre-formed and integrated into the frame profile design before final assembly. Corner clips with pre-configured wire channels are positioned at corner joints, and wire clips are pre-placed within hollows, creating clear, obstacle-free pathways that simplify wire routing while maintaining concealed aesthetics.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The wiring system utilizes multiple dimensions and spaces within the frame structure. Wire channels provide surface-level pathways, while wire clips create three-dimensional routing options within interior hollows, allowing wires to navigate complex geometries without encountering constrictions or obstacles.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Shape

If wires are installed and concealed within frames, then aesthetic appearance is improved, but tracing wires for maintenance or replacement becomes difficult

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidwire tracing
Core Design Contradiction:
ShapeVSEase of repair

Solution Approach 1:

Wire clips and corner clips are designed with visible features that contrast with the frame profile, making wire locations easily identifiable for maintenance purposes while wires remain concealed within the aesthetic framework of the fenestration system.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

Corner clips and wire clips serve as intermediary access points that maintain the concealed aesthetic appearance of wires while providing visible, accessible locations for wire tracing, removal, and replacement during maintenance operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of manufacture

If conventional wiring methods are used, then electrical connections can be made, but wiring appears unsightly and is difficult to manage

Engineering Contradiction:
Improveelectrical connectionVSAvoidaesthetic appearance
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

The wiring system is divided into discrete, aesthetically pleasing components: corner clips at joints, wire clips within hollows, and gaskets for sealing. This segmentation allows wires to be concealed within dedicated channels and pathways, eliminating unsightly exposed wiring while maintaining ease of electrical connection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Gaskets and flexible wire channels provide adaptable pathways that conform to the frame profile geometry, allowing wires to be neatly concealed within flexible, aesthetically integrated channels rather than rigid or exposed routing paths.

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

A frame profile for a fenestration system includes a vertical member, a horizontal member joined to the vertical member at a corner joint, an outer profile cooperatively defined by the vertical and horizontal members and configured to accommodate a wire extending along the outer profile and transitioning between the vertical and horizontal members at the corner joint, and a corner clip mounted to the outer profile at the corner joint and operable to transition the wire between the vertical and horizontal members.
