Solution Overview

Problem

Traditional awnings often suffer from improper operation leading to collisions and damage when closing, as they require reverse rotation, which can cause interference between components.

Innovation Solution

A multi-blade top awning with a 360-degree bidirectional opening/closing mechanism, utilizing a connection rod, rocker arm, worm and gear assembly, and power source, allowing continuous rotation and eliminating the need for reverse rotation during closure, and featuring a double-fastening structure between ring beams and stand columns for enhanced reliability and ease of assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional forward rotation opening and reverse rotation closing mode is used, then the awning can be opened and closed, but component interference and collision damage may occur during closing operation

Engineering Contradiction:

Improveopening and closing operationVSAvoidcomponent damage prevention

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent inverts the traditional operation mode by allowing the blade top plate to open and close through continuous unidirectional rotation rather than forward rotation for opening and reverse rotation for closing. This inversion eliminates the harmful reverse rotation motion that causes component interference and collision damage, while maintaining the functional capability of opening and closing the awning.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent implements continuous unidirectional rotation of the blade top plate through the linkage strip and rocker arm mechanism, eliminating the intermittent forward-reverse rotation pattern. This continuous action ensures smooth operation without sudden reversals that cause component collision, thereby improving reliability while maintaining ease of operation.

Inventive Principle:

Principle #20Continuity of useful action

2Adaptability or versatility

If reverse rotation is used for closing the blade top plate, then the awning can be closed, but shutter transmission mechanism and blade top plate interfere and collide

Engineering Contradiction:

Improveclosing functionVSAvoidcomponent interference and collision

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent applies inversion by replacing the traditional reverse rotation closing mechanism with a unidirectional continuous rotation system. The linkage strip and rocker arm are designed to convert the rotational motion into effective closing action without requiring reverse rotation, thereby eliminating the harmful interference and collision between the shutter transmission mechanism and blade top plate while preserving the closing function.

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of manufacture

If traditional opening and closing mechanism is used, then the awning operates, but additional structural components like angle irons are needed

Engineering Contradiction:

Improveassembly simplicityVSAvoidstructural components quantity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges the functions of multiple components into an integrated linkage strip and rocker arm assembly. This combined structure performs both the opening and closing operations through continuous unidirectional rotation, eliminating the need for separate angle iron components and simplifying the overall structure. The merged design reduces the quantity of structural components while maintaining manufacturing ease through standardized connection methods.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A multi-blade top awning includes an awning frame. A blade top plate, a linkage strip for driving the blade top plate to be opened/closed and a driving mechanism are cooperatively mounted on the awning frame. The driving mechanism includes a connection rod, a rocker arm, a worm and gear assembly and a power source. The connection rod is used for driving the linkage strip to move, the rocker arm is used for driving the connection rod to move, the worm and gear assembly is used for driving the rocker arm to rotate, and the power source is used for providing power for the worm and gear assembly. The rocker arm can rotate by 360 degrees around the worm and gear assembly, such that the blade top plate is opened/closed, a manual rocker does not need to be rotated in a reverse direction when the blade top plate is closed.
