Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If tattoo machines use wireless battery packs for portability, then ease of operation is improved, but power delivery capability and operational duration are limited

Engineering Contradiction:
ImproveportabilityVSAvoidpower delivery capability
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The system dynamically switches between wireless battery-powered mode and wired power mode based on operational needs. The adapter device enables on-the-fly transition from battery operation to AC-powered operation, allowing the tattoo machine to adapt its power source characteristics to match the demands of different tattooing scenarios.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If tattoo machines are designed with fixed configurations, then manufacturing precision is improved, but adaptability and modularity are reduced

Engineering Contradiction:
Improvefixed configurationVSAvoidmodularity
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The system is divided into separate functional modules: the tattoo machine itself, removable battery packs, and an adapter device for wired power. This segmentation allows each component to be optimized independently while enabling flexible reconfiguration. The adapter device serves as a modular interface that can be attached or removed based on power delivery requirements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adapter device serves multiple functions: it provides AC power input, interfaces with the tattoo machine's power receptacle, and enables wired power delivery. This multi-functional component allows a single tattoo machine design to support both wireless battery operation and wired AC-powered operation, increasing system versatility without requiring multiple specialized machines.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Power

If tattoo machines use bulky components for power delivery, then power delivery capability is improved, but device complexity and ease of operation are reduced

Engineering Contradiction:
Improvepower delivery capabilityVSAvoidbulkiness
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

The power delivery capability is extracted from the main tattoo machine body and provided through a separate adapter device. This allows the tattoo machine to maintain a compact, simple design while still supporting high-power AC-powered operation when needed. The bulky power delivery components are contained in the removable adapter rather than being integrated into the permanent structure.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

An adapter for use with a tattoo machine is disclosed. The adapter may enable a tattoo machine configured with a wireless battery pack to switch to a wired configuration by removing the wireless battery pack and replacing it with the adapter. One end of the adapter may be affixed to a portion of the tattoo machine so that the adapter may deliver power to the componentry of the tattoo machine to facilitate the operation of the tattoo machine. The other end of the adapter may include a connector for enabling connection of the adapter to a power supply or power source so that power may be delivered from the power supply or power source through the adapter and to the tattoo machine. When the tattoo machine is powered, the motor of the tattoo machine may reciprocate a needle included in a needle cartridge affixed to the tattoo machine.
