Solution Overview
Problem
Conventional gate opening apparatuses require complex and troublesome mechanical steps to disengage the clutching device for manual operation when electricity is cut off, making it inconvenient for users, especially during non-business hours.
Innovation Solution
A gate opening apparatus that allows manual opening and closing of a gate without using a clutching device, featuring a motor and gear assembly where the motor is cut off from electricity to exert minimal mechanical resistance, enabling easy manual operation.
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 troublesome
Solution Approach 1:
The patent removes the clutching device from the system entirely. Instead of using a clutching device to disengage the motor from the gear assembly for manual operation, the invention directly couples the motor to the gear rod through a simple connection structure, allowing manual operation without any disengagement steps.
Solution Approach 2:
The patent segments the operation modes by using the motor's electromagnetic resistance characteristics - when powered, the motor provides resistance to prevent manual operation; when unpowered, the resistance disappears allowing manual operation. This eliminates the need for mechanical segmentation via clutching devices.
2Adaptability or versatility
If a clutching device is used to disengage the gear assembly from the motor for manual operation, then manual operation is enabled, but the mechanical steps become complicated and require technician assistance
Solution Approach 1:
The patent extracts and removes the clutching device from the system. The motor is directly connected to the gear rod through a simplified coupling structure, eliminating all complex mechanical disengagement steps required by traditional clutching devices.
Solution Approach 2:
The motor itself provides the switching mechanism between power mode and manual mode through its electromagnetic characteristics. When electricity is cut off, the motor automatically transitions from providing resistance to allowing free rotation, eliminating the need for external clutching mechanisms or technician intervention.
3Reliability
If assistance from a technician is required to operate the gate during non-business hours, then proper operation can be achieved, but user convenience and accessibility are severely reduced
Solution Approach 1:
The system enables users to perform manual operation themselves without requiring technician assistance. The direct coupling between motor and gear assembly allows any user to manually operate the gate by simply rotating the gear rod when power is unavailable.
Solution Approach 2:
By removing the clutching device and its complex engagement/disengagement procedures, the patent makes the system accessible to ordinary users rather than requiring trained technicians to perform mechanical operations during emergencies.
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 seamless manual operation of the gate during power outages without the need for complex mechanical disengagement, providing convenience and accessibility to users at all times.
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 for a door gate includes a housing, a motor, and a gear assembly. The gear assembly includes a gear rod and a driven member. The gear rod has one end connected to the motor without connecting through any clutching device, and another end extending toward a mounting portion of the housing. The driven member engages with 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. The gate opening apparatus is arranged to be selectively operated between a power mode and a manual mode, 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 move the door gate for opening or closing thereof.
