Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals frequently need to get haircuts due to unsightly hair growth above the ear, despite the rest of their hair being at an acceptable length, leading to unnecessary expenses, as existing solutions do not effectively allow for DIY trimming of this excess hair into a smooth and tidy curve.
Innovation Solution
A trimming profile element curved to fit around a human ear, combined with an electric clippers attachment, featuring interlocking teeth to hold hair and guide channels to prevent unwanted cutting, allowing for customizable and efficient trimming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional clippers are used to trim hair around the ear, then the clipper blades can reach the hair, but it is difficult to control the cutting path to create a smooth curve
Solution Approach 1:
A guide attachment is introduced as an intermediary component between the clippers and the ear area. This guide attachment includes a curved guide surface that defines the desired cutting path and a positioning element that contacts the ear to stabilize the guide attachment. The guide attachment mediates the interaction between the clipper and the hair, enabling precise curved trimming without requiring manual dexterity to freehand the curve.
2Object-affected harmful factors
If the clipper attachment blocks most of the clipper teeth, then safety is improved by preventing unwanted cutting, but the ability to trim hair is reduced
Solution Approach 1:
The guide attachment features a curved guide surface with a specific geometry that locally exposes only the portion of clipper teeth needed for trimming hair around the ear. The guide surface is designed with a controlled opening that allows selective access to the clipper blades, providing safety by blocking most teeth while maintaining trimming effectiveness through precise local exposure of the cutting elements.

AI summary
A curved trimming profile shaped to border a portion of the ear forms a channel for an electric clippers attachment to follow and trim hair around the ear. The trimming profile has two portions that clamp over the hair. Each portion has a track, and the tracks form the profile channel when the portions are clamped together. Teeth between the portions hold the hair in place. The attachment has a channel guide for engaging with the profile channel and a groove which allows clipper blades to trim hair as the clippers travel. The rest of the clipper blades are blocked by the attachment.
