Solution Overview
Problem
Tattoo machine power supplies are inconvenient due to the need for wired connections, which obstruct the machine's operation and require separate charging equipment, limiting ease of use and flexibility.
Innovation Solution
A wireless power supply system that is removably connected to the tattoo machine's motor, featuring rechargeable batteries and input buttons to adjust voltage, allowing for variable motor speed without wires, and is easy to manufacture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wired power supply is used for the tattoo machine, then the machine can be powered continuously, but the power cable obstructs the machine and reduces ease of operation
Solution Approach 1:
The power supply unit is extracted from the fixed wall socket configuration and integrated into a portable wireless battery pack that attaches directly to the tattoo machine. This removes the obstructing power cable while maintaining continuous power supply capability.
Solution Approach 2:
A wireless power transmission interface is introduced as an intermediary between the battery pack and the tattoo machine motor. This allows power transfer without physical wire connection, eliminating the obstructing cable while ensuring reliable power delivery.
2Ease of operation
If a separate base unit is used for charging the battery, then the battery can be recharged, but it requires additional equipment and reduces convenience
Solution Approach 1:
The charging function is merged with the tattoo machine itself. The USB port is integrated into the machine body, allowing the battery pack to be recharged directly through the machine without requiring a separate base unit or charging equipment.
Solution Approach 2:
The tattoo machine provides self-charging capability through its integrated USB port. The operator can recharge the battery pack directly at the workstation without needing external charging equipment, making the system self-sufficient.
3Adaptability or versatility
If fixed voltage is supplied to the motor, then the power supply is simple, but the motor speed cannot be adjusted
Solution Approach 1:
The power supply transitions from fixed voltage to dynamically adjustable voltage. Up and down input buttons enable real-time modification of voltage levels supplied to the motor, allowing speed variation while maintaining a relatively simple control interface.
Solution Approach 2:
The voltage parameter supplied to the motor is made variable through input controls. The battery pack can adjust voltage levels to control motor speed, providing adaptability without requiring complex control systems.
