Wireless Tattoo Machine Side Wall Button Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless tattoo machines require both hands to operate due to the placement of control buttons at the top, making it inconvenient for one-handed use during tattooing.
Innovation Solution
A wireless tattoo machine design with a control circuit board and buttons integrated into the shell, allowing for one-handed operation, featuring a shell, electric motor, batteries, and a steel rod with an eccentric wheel, where the control circuit board is connected to the batteries and electric motor in series, and buttons are accessible on the side wall for finger control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If control buttons are positioned at the top of the wireless tattoo machine, then the structure is simple and easy to manufacture, but the buttons cannot be controlled with one hand during tattooing operation
Solution Approach 1:
The control buttons are relocated from the top surface to the side wall of the shell, changing the spatial dimension of button placement. This allows the operator to access buttons with fingers while holding the machine in one hand, resolving the contradiction between one-handed operation capability and structural simplicity.
2Ease of operation
If control buttons are positioned at the top of the shell, then the device structure is compact, but fingers cannot press the buttons during operation
Solution Approach 1:
Buttons are moved from the top surface to the side wall, utilizing the vertical dimension of the shell. This repositioning makes buttons accessible to fingers while maintaining a compact overall device shape, solving the contradiction between button accessibility and shell structure configuration.
3Volume of moving object
If batteries and control circuit board are arranged in a triangular shape at the edge of the hollow pipe, then space utilization is improved and compactness is enhanced, but the structural design becomes more complex
Solution Approach 1:
The batteries and control circuit board are nested within the shell structure at the edge of the hollow pipe, arranged in a triangular configuration. This nesting approach maximizes space utilization within the available volume while integrating the components into the existing shell structure, balancing space efficiency with structural complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
