Hair Clipper Leveling Device With Integrated Digital Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair clipper devices lack the ability to precisely trim lines into hair as they do not provide a means to accurately measure deflection from a vertical axis, relying on light emitters or bubble levels that do not display numerical indications.
Innovation Solution
A hair clipper device with a level unit integrated into the handle that measures deflection along its lengthwise axis and features a display showing numerical indicia to indicate the degree of deflection, allowing for precise orientation and trimming of lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a bubble level or light emitter is used to indicate deflection, then the device can show whether the clipper is tilted, but it cannot provide numerical indication of the degree of deflection
Solution Approach 1:
The patent replaces the mechanical bubble level system with an electronic accelerometer-based measurement system. The accelerometer electronically detects deflection angles and converts them into numerical signals displayed on an LCD screen, providing precise quantitative measurement rather than qualitative bubble position indication.
Solution Approach 2:
The patent introduces an intermediary electronic display system between the deflection detection mechanism and the user. The accelerometer detects physical deflection, converts it to electrical signals, and the LCD display presents this information numerically, serving as an intermediary that transforms mechanical motion into comprehensible numerical data.
2Measurement precision
If no deflection measurement device is attached to the clipper, then the device remains simple and lightweight, but the user cannot accurately measure the angle for precise line trimming
Solution Approach 1:
The patent merges the level measurement function directly into the clipper handle by integrating the accelerometer and display unit into the existing clipper structure. This combination eliminates the need for separate external level devices while providing accurate angle measurement capability built into the trimming tool itself.
Solution Approach 2:
The clipper handle is designed to serve multiple functions: it provides mechanical support for the trimming head, houses the motor, and now also contains the level measurement and display system. This multi-functionality reduces the need for separate devices and integrates measurement capability into the primary tool.
3Adaptability or versatility
If a separate external level device is used with the clipper, then the measurement function can be added, but the device becomes less integrated and more difficult to operate as a unified system
Solution Approach 1:
The level measurement system is merged into the clipper handle, creating a unified integrated device. The accelerometer and display are positioned within the handle structure, allowing the user to operate the clipper and view angle measurements as a single cohesive system rather than managing separate tools.
Solution Approach 2:
The integrated display unit provides real-time feedback directly to the user during operation, eliminating the need for external measurement devices or separate observation tools. The system serves itself by providing immediate visual information about deflection angle while the clipper is being used.

AI summary
A hair clipper leveling device for precisely trimming lines into a person's hair includes a clipper which includes a handle and a trimming head movably attached to the handle to trim hair when the handle is gripped. A level unit is integrated into the handle of the clipper and the level unit is oriented to measure deflection of the clipper along a lengthwise axis of the clipper. In this way the level unit facilitates a user to trim precisely measured lines in the hair. The level unit includes a display which displays indicia comprising numbers to indicate a degree of deflection from the lengthwise axis.
