Solution Overview
Problem
Existing electric apparatuses with doors require manual operation, which can be inconvenient when users need to hold items or when doors are not closed properly.
Innovation Solution
An electric apparatus with a housing, two doors, and motors for each door, controlled by a processor to automatically open and close the doors independently or sequentially based on signals, ensuring complete closure without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the door is opened or closed manually by the user, then the device complexity is reduced, but the ease of operation deteriorates when the user needs to hold items with both hands
Solution Approach 1:
The door opening/closing device enables the door to open or close automatically without manual intervention. The processor controls the motor to rotate the door based on detected signals, allowing the system to serve itself by automatically performing the door operation function that would otherwise require user action.
Solution Approach 2:
The patent replaces the manual mechanical operation of the door with an automated electromechanical system. A motor coupled to the door and controlled by a processor substitutes for manual user interaction, converting electrical control signals into mechanical door movement to achieve automated opening and closing.
2Productivity
If both doors are closed simultaneously, then the productivity is improved, but the reliability deteriorates due to potential interference between doors
Solution Approach 1:
The patent divides the door closing operation into separate sequential actions for each door rather than simultaneous closure. The processor controls each door independently, first closing one door completely before initiating closure of the other door, thereby eliminating interference between the two doors while maintaining overall efficiency.
Solution Approach 2:
The system performs preliminary detection to determine whether both doors need to be closed, then executes the closing operation in a predetermined sequential order. This preliminary assessment and structured execution ensure that doors are closed reliably without interference while maintaining productivity.
3Reliability
If the door is not closed completely by the user, then the ease of operation is maintained, but the reliability deteriorates as the door may remain open
Solution Approach 1:
The processor continuously detects the position and closure state of the door during the closing operation. Based on this feedback information, the processor determines whether the door has been closed completely and can initiate a second closing operation if needed, ensuring reliable closure while requiring minimal user intervention.
