Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tattoo chairs lack adjustability, making it inconvenient to tattoo regularly tattooed parts of the body, leading to discomfort for both the artist and the person receiving the tattoo.
Innovation Solution
A tattoo chair with a rotatable backrest, adjustable hydraulic brace, and customizable armrests and leg rests, allowing for various poses and improved comfort through gear racks, springs, and detachable components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the backrest is fixed vertically to the seat, then the chair structure is simple and stable, but it is inconvenient to tattoo various body parts such as back, stomach, waist and leg
Solution Approach 1:
The backrest is designed to be rotatable relative to the seat through a hinge connection, allowing it to change from a fixed vertical position to an inclined position. This dynamic adjustment enables the chair to adapt to different body parts for tattooing, resolving the contradiction between structural simplicity and adaptability.
2Ease of operation
If the brace height is fixed, then the chair structure is simple, but it brings inconveniences in use and causes fatigue
Solution Approach 1:
A hydraulic lifting device is introduced to enable height adjustment of the brace. This allows the chair to be easily adjusted to different heights for comfort and accessibility, resolving the contradiction between ease of use and structural simplicity through hydraulic technology.
3Ease of operation
If the armrests are fixed on both sides of the seat, then the chair structure is simple, but it causes discomfort for persons with arms getting tattoos
Solution Approach 1:
The armrests are designed to be movable rather than fixed, allowing them to be adjusted or removed as needed. This dynamic design provides comfort for persons getting tattoos on their arms while maintaining relative structural simplicity.
4Adaptability or versatility
If the person sits right toward the front of the chair, then it is convenient to tattoo the shoulder, but it is inconvenient to tattoo other regularly tattooed parts of the body
Solution Approach 1:
The rotatable backrest allows the person to adopt different poses by adjusting the backrest angle, enabling convenient access to various body parts including back, stomach, waist and leg, while maintaining ease of operation through simple rotational movement.
