Umbrella Automatic Manual Opening Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric umbrellas are complex and expensive to produce, and they lack a reliable mechanism for opening and closing when the power motor is not operational, such as in the case of an empty battery.
Innovation Solution
A combined automatic and manual umbrella opening and closing structure that includes a motor structure with a screw rod and power motor, connected to a bevel gear system, and a handle structure with a clutch transmission mechanism, allowing the umbrella to be opened and closed either automatically with electricity or manually without power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If an electric umbrella structure with power motor and transmission mechanism is used, then the automatic opening and closing function is achieved, but the device complexity and manufacturing cost increase significantly
Solution Approach 1:
The patent integrates both automatic and manual opening/closing capabilities into a single umbrella structure. The handle can operate in two modes: electric mode where the power motor drives the screw rod for automatic opening/closing, and manual mode where the user directly rotates the handle to drive the screw rod through the transmission mechanism. This multi-functionality allows the device to provide automated convenience while maintaining mechanical backup, resolving the contradiction between automation and complexity.
2Extent of automation
If an electric umbrella structure with power motor is used, then automatic opening and closing function is achieved, but the reliability decreases when power supply is depleted
Solution Approach 1:
The patent incorporates a manual operation mechanism as a backup system that is always available regardless of power supply status. The transmission mechanism (bevel gears and screw rod) is designed to accept input from both the power motor and direct manual rotation of the handle. This beforehand cushioning ensures that even when the power motor fails or the battery is depleted, the umbrella can still be opened and closed reliably through manual operation, thus resolving the reliability issue.
3Extent of automation
If a complex transmission structure with multiple components is used, then automatic opening and closing function is achieved, but the ease of manufacture decreases
Solution Approach 1:
The patent divides the opening/closing mechanism into distinct functional modules: the power motor module, the transmission module (bevel gears and screw rod), and the handle module. Each module can be manufactured and assembled separately. The bevel gears provide a compact and efficient transmission solution that is relatively simple to manufacture compared to more complex mechanisms. This segmentation allows for standardized production of each component, improving overall manufacturing ease while maintaining the automatic function.
