Innovation Solution
A lifting device with an automatic/manual switching structure, featuring a handle driving part with a clutch gear system, elastic support, and electromagnetic clutch, allowing for automatic or manual operation, along with wireless control and real-time monitoring through a terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If an electric actuator is used for automatic window lifting, then the window can be opened and closed automatically, but the window cannot be lifted when the electric actuator fails
Solution Approach 1:
The clutch gear is designed with different functional zones: an engaged state for automatic operation and a disengaged state for manual operation. This local differentiation of function within the same mechanism allows the system to switch between automatic and manual modes, ensuring reliability even when the electric actuator fails.
Solution Approach 2:
The clutch gear can dynamically switch between two states: engaged with the output shaft for automatic operation, and disengaged to allow manual operation. This dynamic adaptability enables the system to respond to different operational conditions, maintaining reliability by allowing manual intervention when automatic operation fails.
2Area of stationary object
If a large-sized lift sliding window is used, then the window provides good isolation and ventilation, but a large amount of force is required for manual opening and closing
Solution Approach 1:
The patent replaces the direct manual mechanical operation with an electric actuator that provides automated lifting force. The actuator's output shaft drives the window lifting mechanism, substituting the need for large manual forces with an electrically-driven mechanical system that can handle large window sizes effortlessly.
3Extent of automation
If the clutch gear is always engaged with the output shaft, then automatic operation is continuous, but manual operation becomes impossible
Solution Approach 1:
The clutch gear is designed to be dynamically controllable, allowing it to switch between engaged and disengaged states. When engaged, automatic operation continues; when disengaged, manual operation becomes possible. This dynamic state change capability provides both continuous automatic operation and manual operation versatility.
Solution Approach 2:
The clutch mechanism serves multiple functions: it can remain engaged for continuous automatic operation, be disengaged for manual operation, and provide a transition state for mode switching. This multi-functionality allows the same mechanism to support both automatic and manual operational modes.
4Ease of operation
If the clutch gear is always disengaged from the output shaft, then manual operation is always possible, but automatic operation cannot be performed
Solution Approach 1:
The clutch gear's engagement state is dynamically controllable based on operational requirements. When disengaged, manual operation is always possible; when engaged, automatic operation is enabled. This dynamic state management allows the system to switch between manual availability and automatic capability as needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables reliable automatic operation and easy manual override of lift sliding windows, reducing operational force and allowing remote monitoring and control, enhancing user convenience and functionality.
Implementation Method 1
a clutch gear (619) configured to connect the gear trains (615) and the shaft (617) to each other so that the gear trains (615) are engaged with the shaft (617), wherein the clutch gear (619) is capable of reciprocating in a sliding manner in an axial direction on the identical axis line of the shaft (617) for selective power transmission and is elastically supported at one side by an elastic member (618)
