Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a wired power connection is used to power the tattoo device, then the device can operate continuously, but the maneuverability and visibility for the tattoo artist deteriorates
Solution Approach 1:
The patent extracts the power source from the external wired connection and places it within the device itself through a rechargeable battery. This removes the obstructing wire while maintaining continuous operation capability through internal power supply.
Solution Approach 2:
The patent replaces the mechanical wired power connection system with an electrical battery-powered system. This substitution eliminates the physical wire constraint while providing continuous power through the rechargeable battery and motor assembly.
2Duration of action of stationary object
If a wired power connection is used to power the tattoo device, then the device can operate continuously, but the time required to complete tattoos increases
Solution Approach 1:
By extracting the power source from external wiring to internal battery power, the patent eliminates the time-consuming adjustments and movements required to manage the wired connection, thereby reducing overall tattoo completion time while maintaining continuous operation.
3Duration of action of stationary object
If a wired power connection is used to power the tattoo device, then the device can operate continuously, but the ability to sketch intricate details deteriorates
Solution Approach 1:
By removing the wired power connection, the patent eliminates the physical obstruction that interferes with precise hand movements required for intricate detail work, while the internal battery maintains continuous operation capability.
4Ease of operation
If the motor housing and grip are made rotatable for needle depth adjustment, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The patent applies dynamics by making the motor housing and grip rotatable relative to each other, allowing the needle cartridge depth to be adjusted through rotation. This dynamic adjustment mechanism improves ease of operation while maintaining a relatively simple structural implementation.
Data Source
AI summary
A wireless tattoo device is disclosed. The device includes an electronics housing, a control panel, a power source, and a motor assembly driven by the power source. A motor housing is attached to the electronics housing, and the motor housing defines a passage dimensioned to receive a portion of the motor assembly. A grip defines an opening dimensioned to receive an end of the motor housing. The motor housing is configured to receive a needle cartridge. The motor housing and the grip are rotatable relative to each other such that a depth of the needle cartridge relative to the grip varies based on a relative rotation position between the motor housing and the grip.
