Solution Overview
Problem
Conventional door lock mechanisms for electrical equipment, such as dishwashers, require manual operation and lack the ability to automatically adjust the door position for efficient ventilation during drying processes, leading to inefficiencies in space usage and user convenience.
Innovation Solution
A door lock assembly with a slider, slider gear, and bias device that allows for automatic opening and closing of the door, utilizing a rotating bias device and motor-driven gear system to control the door's position, enabling it to move between open, closed, and intermediate positions for enhanced ventilation and user accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the bias device applies bias force on the outer side of the slider, then the slider can be driven to move, but the bias device needs to generate a large bias force to overcome the unnecessary torque and the slider needs to overcome additional acting force
Solution Approach 1:
The patent changes the application point of the bias force from the outer side of the slider to the inner side, aligning it with the moving path. This dimensional repositioning eliminates the unnecessary torque component and allows the bias force to act directly in the direction of motion, reducing the total force required.
Solution Approach 2:
The patent modifies the parameters of force application by changing both the position (from outer side to inner side) and direction of the bias force. This parameter optimization ensures the bias force acts collinearly with the slider's moving path, minimizing energy loss to unnecessary torque.
2Stability of the object's composition
If the driving device is in rigid connection with the slider, then the driving device is fixed relative to the door lock box, but this is not conducive to meeting the requirement for a compact door lock box to make full use of space
Solution Approach 1:
The patent replaces the rigid fixed connection with a dynamic adjustable connection. The driving device can now be positioned at different locations along the slider's moving path, allowing the system to adapt its configuration based on space requirements while maintaining functional stability during operation.
Solution Approach 2:
The patent separates the driving device from the slider body, allowing them to be independently positioned. The driving device is mounted on the door lock box at an optimized location rather than being rigidly attached to the slider, enabling better space utilization while maintaining functional connection through the gear-rack mechanism.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for efficient automatic door control, reducing the need for manual operation, optimizing space usage, and improving user convenience by enabling the door to be automatically opened for ventilation during the drying process, while maintaining compactness and simplicity in design.
Implementation Method 1
the slider gear is mounted in the door lock slider groove, the slider gear is configured to rotate about a rotating shaft, the slider gear engages with the door lock slider rack, and the slider gear and the door lock slider rack are configured such that: when the slider gear rotates about the rotating shaft in a first rotation direction or a second rotation direction, the door lock slider reciprocates in the first linear direction or the second linear direction
Implementation Method 2
the bias device is configured to drive the slider gear, such that the slider gear drives the door lock slider in the second linear direction

AI summary
A driving device for driving a door lock assembly, the door lock assembly being configured to actuate a door of an electrical equipment and comprising a door lock slider. The driving device includes a driving gear and a driving rack, wherein a gear teeth driving portion and a toothless portion are disposed on a periphery of the driving gear, and the driving gear is rotatable unidirectionally. The driving rack can reciprocate in a first and a second linear direction and drive the door lock slider to move in the first linear direction. The driving rack engages with the gear teeth driving portion when driving the door lock slider to move in the first linear direction. A movement route of the driving rack corresponds to the toothless portion when the door lock slider moves in the second linear direction to reduce resistance. The door lock box is connected to the driving device by a pulling rope.
