Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fastener is used for manual opening of the stopper, then the stopper can be extracted, but the fastener becomes large in size and inaesthetic, and frequent opening may easily damage the fastener
Solution Approach 1:
The patent replaces the mechanical fastener system with a magnetic field-based ejection system. The magnetic module generates magnetic force to automatically eject the stopper body, eliminating the need for manual fastener operation and large opening mechanisms, thereby improving aesthetic appearance while maintaining ease of operation.
Solution Approach 2:
The stopper ejection system operates automatically through magnetic force generation when electrical signal is applied, without requiring manual manipulation of fasteners or other mechanical components. The system serves itself by converting electrical energy to magnetic force for automatic ejection.
2Ease of operation
If a fastener is used for manual opening of the stopper, then the stopper can be extracted, but frequent opening may easily damage the fastener to make it impossible to continue extracting the stopper
Solution Approach 1:
The patent replaces the mechanical fastener system with a magnetic field-based ejection system. The magnetic module generates magnetic force to automatically eject the stopper body, eliminating the need for manual fastener operation and large opening mechanisms, thereby improving aesthetic appearance while maintaining ease of operation.
Solution Approach 2:
The stopper ejection system operates automatically through magnetic force generation when electrical signal is applied, without requiring manual manipulation of fasteners or other mechanical components. The system serves itself by converting electrical energy to magnetic force for automatic ejection.
3Extent of automation
If a pin-poking stopper is used, then the stopper can be ejected by pushing and pressing, but an auxiliary tool such as a pin is required and operation becomes difficult
Solution Approach 1:
The patent replaces manual mechanical ejection methods with an electromagnetic ejection system. The magnetic module generates magnetic force to automatically eject the stopper body when electrical signal is applied, eliminating the need for auxiliary tools like pins and simplifying operation to just activating the electrical signal.
Solution Approach 2:
The stopper ejection system operates automatically through magnetic force generation when electrical signal is applied, without requiring manual manipulation of fasteners or other mechanical components. The system serves itself by converting electrical energy to magnetic force for automatic ejection.
4Extent of automation
If a pin-poking stopper is used, then the stopper can be ejected by pushing and pressing, but the stopper may not be extracted because an auxiliary tool is not carried
Solution Approach 1:
The patent replaces manual mechanical ejection methods with an electromagnetic ejection system. The magnetic module generates magnetic force to automatically eject the stopper body when electrical signal is applied, eliminating the need for auxiliary tools like pins and simplifying operation to just activating the electrical signal.
Solution Approach 2:
The stopper ejection system operates automatically through magnetic force generation when electrical signal is applied, without requiring manual manipulation of fasteners or other mechanical components. The system serves itself by converting electrical energy to magnetic force for automatic ejection.
