Solution Overview

Problem

Traditional methods for cutting split ends of hairs, such as using scissors and a comb, are time-consuming and laborious, and do not facilitate easy and accurate trimming.

Innovation Solution

A hair clipper that can be easily attached to and detached from a hair trimmer, featuring a guide structure with a reservoir for conditioning and a clamp structure for precise cutting of split ends, allowing for quick and damage-free trimming.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If scissors and comb are used to cut split ends, then cutting can be performed, but the process is time-consuming and laborious

Engineering Contradiction:
Improvecutting speedVSAvoidmanual effort
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent combines the hair trimmer and hair clipper into a single integrated device. The hair clipper includes a clamp structure that couples to the blade section of the hair trimmer, merging two separate tools (trimmer and clipper) into one unified system that performs both trimming and splitting functions simultaneously, thereby increasing productivity and reducing manual effort

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated device serves multiple functions: the hair trimmer portion cuts hair while the hair clipper portion specifically targets and removes split ends. This multi-functional design eliminates the need for separate scissors and comb operations, significantly improving cutting speed and reducing the laborious nature of traditional split end removal

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

2Loss of time

If traditional scissors and comb method is used, then split ends can be cut, but the process is laborious and time-consuming

Engineering Contradiction:
Improvetime for cuttingVSAvoidcutting efficiency
Core Design Contradiction:
Loss of timeVSProductivity

Solution Approach 1:

By merging the hair trimmer and hair clipper functions into one device, the patent enables simultaneous operation of both trimming and split end removal. This integration dramatically reduces the time required for the cutting process while significantly improving overall cutting efficiency compared to using separate tools

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If a removable hair clipper is designed, then easy attachment and detachment is achieved, but device complexity increases

Engineering Contradiction:
Improveattachment easeVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The device is segmented into distinct modular components: the hair trimmer body, the blade section, and the hair clipper assembly with its clamp structure. This segmentation allows the hair clipper to be easily attached to and detached from the hair trimmer through the clamp-blade interface, simplifying operation while managing complexity through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The clamp structure incorporates a movable clip that can be pivoted between a forward position (for attachment) and a rearward position (for detachment). This dynamic mechanism enables easy attachment and detachment of the hair clipper to the hair trimmer, improving ease of operation while the modular nature keeps overall complexity manageable

Inventive Principle:
Principle #15Dynamics

AI summary

A hair clipper for a hair trimmer includes a body including a clamp structure and having a first longitudinal end and a second longitudinal end, a first wall arranged proximate to the first longitudinal end of the clamp structure and extending substantially perpendicularly from the clamp structure, and a second wall arranged substantially parallel to and spaced apart from the first wall defining a gap therebetween. The hair clipper includes a guide structure pivotally coupled to the body and adapted to move in an open position and a closed position relative to the body. The guide structure includes a base and a plate extending substantially perpendicularly from the base towards the clamp structure, and a reservoir defining a chamber with a conditioner disposed inside the chamber. In the closed position of the guide structure, the plate is arranged between the first wall and the second wall.
