Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gate opening apparatuses require complex mechanical steps to manually operate the door gate when electricity is cut off, making it difficult for lay users to perform manual opening or closing without technical assistance.
Innovation Solution
A gate opening apparatus designed with a gear assembly that allows manual operation without a clutching device, featuring a motor-driven gear rod and driven member that can pivot or slide the door gate, selectable between power and manual modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a clutching device is used to allow manual operation when electricity is cut off, then manual operation capability is achieved, but the operation procedure becomes complicated and requires technical assistance
Solution Approach 1:
The invention removes the clutching device from the system entirely. Instead of using a clutching device to disengage the gear assembly from the motor for manual operation, the patent directly connects the gear rod to the motor output shaft, eliminating the need for any clutching mechanism. This extraction of the problematic component resolves the contradiction by enabling simple manual operation without complicated procedures.
Solution Approach 2:
The invention segments the operation into two distinct modes: power mode where the motor drives the gear rod, and manual mode where the user directly operates the gear rod. The gear rod serves dual purposes - it can be driven by the motor when powered, or manually rotated by the user when electricity is unavailable. This segmentation allows the same component to fulfill multiple functions without requiring complex switching mechanisms.
2Adaptability or versatility
If a clutching device is used to enable manual operation, then manual operation is possible, but the device complexity increases
Solution Approach 1:
The invention extracts and removes the clutching device from the mechanical structure. By eliminating this component entirely and directly connecting the gear rod to the motor output shaft, the patent reduces device complexity while maintaining manual operation capability. The simplified structure requires fewer parts and less complex assembly.
Solution Approach 2:
The gear rod is designed to serve multiple functions: it can be rotated by the motor to drive the driven member during powered operation, and it can also be manually rotated by the user during manual operation. This multi-functionality eliminates the need for separate mechanisms for powered and manual modes, thereby reducing overall device complexity.
3Adaptability or versatility
If a clutching device is used for manual operation, then manual mode is available, but the time required for operation increases
Solution Approach 1:
By removing the clutching device entirely, the invention eliminates the time-consuming steps of engaging and disengaging the clutch. Users can immediately transition to manual operation by simply rotating the gear rod without any preliminary mechanical steps, significantly reducing the time loss associated with mode switching.
Solution Approach 2:
The system dynamically adapts between powered and manual modes without requiring mechanical reconfiguration. The gear rod can seamlessly switch between being motor-driven and being manually operated, allowing users to quickly respond to power outages without time-consuming procedural steps.
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 easy manual operation of the door gate during power outages by eliminating the need for clutching devices, allowing users to manually open or close the gate with minimal mechanical resistance.
Implementation Method 1
a gear rod having one end connected to the motor without connecting through any clutching device, and another end extending in the receiving cavity toward the mounting portion of the housing, the gear rod having a plurality of first teeth spirally formed thereon; and a driven member having a plurality of second teeth engaging with the first teeth of the gear rod, in such a manner that when the gear rod is driven to rotate, the driven member is arranged to move along a longitudinal direction of the housing

AI summary
A gate opening apparatus includes a housing, a supporting frame, a motor, a driving member connected to the motor, and a gear assembly. The gear assembly includes a main gear rotatably mounted on the supporting frame and connects to the driving member, and a plurality of driven gears rotatably mounted on the supporting frame. The gate opening apparatus is arranged to be selectively operated between a power mode and a manual mode, wherein in the power mode, the motor is electrically activated to drive the driving member and the main gear to rotate so as to drive the driven gears to rotate and move the door gate to slide, wherein in the manual mode, the motor is cut off from electricity and is arranged to exert minimal mechanical resistance so that a user is able to manually slide the door gate for opening or closing thereof.
