Solution Overview

Problem

Cassette awnings have a visually unappealing appearance due to visible fastening brackets and screws, and are prone to dirt accumulation and damage from environmental influences, leading to potential operational issues.

Innovation Solution

The awning housing is angled at both ends to cover the mounting brackets, integrating diagonal connectors and concealing fastening elements, with optional features like cable ducts, electronic controls, and lighting, ensuring protection from environmental influences and a visually appealing design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional brackets and fastening screws are used to attach the awning to the building, then the awning can be securely mounted, but the fastening elements become visible and aesthetically unappealing

Engineering Contradiction:
Improvesecure mountingVSAvoidvisual appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The fastening elements (brackets and screws) are extracted from the visible exterior and concealed within the housing structure. The housing is designed with angled ends that cover the mounting brackets, removing the visually unappealing fastening elements from the exterior view while maintaining their secure mounting function.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The fastening brackets are nested within the housing structure. The angled ends of the housing enclose and protect the mounting brackets, creating a nested arrangement where the fastening elements are hidden inside the housing while still providing secure attachment to the building.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of manufacture

If traditional fastening elements are exposed on the exterior, then installation is simple, but dirt and rainwater accumulate on the fastenings causing visual impairment and potential damage

Engineering Contradiction:
Improveinstallation simplicityVSAvoiddirt and water accumulation
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The fastening elements are extracted from the exterior surface and concealed within the housing. By removing them from the exposed exterior where dirt and rainwater accumulate, the patent eliminates the harmful effects while maintaining installation simplicity through the integrated housing design.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mounting brackets are nested within the housing structure, protecting them from environmental contaminants. The angled ends of the housing create a protective enclosure that prevents dirt and rainwater from reaching the fastening elements, eliminating accumulation and associated damage.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Shape

If the housing is designed with angled ends to cover the brackets, then visual appearance and protection are improved, but the housing structure becomes more complex

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidhousing structure
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The housing is segmented into distinct components including the main housing body and angled end pieces. This segmentation allows the angled ends to be added as separate elements that cover the brackets, achieving the aesthetic and protective goals while maintaining manufacturing simplicity through modular construction.

Inventive Principle:
Principle #1Segmentation
