Sunshade Edge Strip Rotating Grip for Glazing Grooves

Solution Overview

Problem

Existing sunshade fastening systems for glazed balconies require precise fitting and separate fasteners, leading to increased installation time and costs due to the need for custom-fit components and limitations in attaching to uniform frame profiles or obstructed grooves.

Innovation Solution

A sunshade system with edge strips featuring a gripping projection that fits into a fastening groove and rotates to secure, eliminating the need for separate fasteners by using guide wires to tension and lock the strips in place, allowing for attachment to glazing elements with varying profiles and orientations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate fasteners with tight-fit suspension elements are used to attach sunshade to edge profile, then reliable attachment is achieved, but installation time increases and cost increases due to precise dimensioning requirements and inability to reposition

Engineering Contradiction:

Improveattachment reliabilityVSAvoidinstallation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The invention merges the sunshade edge strip with the gripping projection into a single integrated component. The gripping projection is formed as an extension of the edge strip itself, eliminating the need for separate fasteners and enabling direct attachment to the edge profile through the integrated gripping structure.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The gripping projection serves multiple functions: it acts as both a structural extension of the edge strip and a fastening mechanism that can engage with the fastening groove. This multi-functional design allows the same component to perform both support and attachment roles, reducing the number of parts needed.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If separate fasteners with tight-fit suspension elements are used to attach sunshade to edge profile, then reliable attachment is achieved, but device complexity increases due to multiple components and precise dimensioning requirements

Engineering Contradiction:

Improveattachment reliabilityVSAvoidfastening system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

The invention merges the sunshade edge strip with the gripping projection into a single integrated component. The gripping projection is formed as an extension of the edge strip itself, eliminating the need for separate fasteners and enabling direct attachment to the edge profile through the integrated gripping structure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Shape

If fastening groove is closed or obstructed by wall or adjacent edge profile, then uniform frame profile and compact design are achieved, but attachment of sunshade becomes impossible with conventional fasteners

Engineering Contradiction:

Improveframe profile uniformityVSAvoidattachment adaptability

Core Design Contradiction:

ShapeVSAdaptability or versatility

Solution Approach 1:

Instead of inserting the fastening element from the open end of the fastening groove as with conventional fasteners, the gripping projection approaches the fastening groove from a different direction and engages by rotating into the groove. This inverted approach allows attachment even when the groove end is closed or obstructed.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The gripping projection is designed to rotate from an initial position alongside the edge profile into the fastening groove. This dynamic rotation motion enables the projection to overcome obstacles at the groove end and achieve secure attachment in configurations where static fasteners would fail.

Inventive Principle:

Principle #15Dynamics

AI summary

The sunshade comprises a first edge strip (20) and a second edge strip, at least two conductor wires (24a) extending from the first edge strip to the second edge strip and a movable protective curtain suspended from the conductor wires. The first edge strip and/or the second edge strip have a substantially rigid gripping projection (56) for attachment to the edge profile (13) of the glazing. The method comprises attaching the sunshade to a glazing element having a first edge profile and a second edge profile, wherein the edge profiles have a fastening groove (40) in the longitudinal direction of the edge profile. The method comprises providing a substantially rigid gripping projection with a tip portion (54) on the first edge strip, placing the first edge strip in a first position alongside the first edge profile, fitting the tip portion of the gripping projection of the first edge strip into the fastening groove of the first edge profile, and rotating the first edge strip about its longitudinal axis to a second position so that at least the tip portion of the gripping projection moves into the locking groove.
