Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improveease of useVSAvoidwired connection requirement
Core Design Contradiction:
Ease of operationVSDevice complexity

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Engineering Contradiction:
ImproveconvenienceVSAvoidseparate charging equipment
Core Design Contradiction:
Ease of operationVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If fixed voltage is supplied to the motor, then the power supply is simple, but the motor speed cannot be adjusted

Engineering Contradiction:
Improvespeed controlVSAvoidvoltage control mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #35Parameter changes
