Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional hair scissors are used to cut split ends, then the barber can manually sort and cut hairs, but the process is troublesome and time-consuming
Solution Approach 1:
The patent replaces the manual mechanical system of traditional hair scissors with an automated electric hair clipper system. The electric drive assembly generates reciprocating motion through eccentric mechanisms, eliminating the need for manual sorting and cutting operations. This substitution of manual mechanical operations with an automated electromechanical system directly addresses the contradiction by improving ease of operation while reducing time loss.
Solution Approach 2:
The electric hair clipper enables self-service hair clipping by providing an automated device that performs both sorting and cutting functions. The reciprocating motion of the movable blade relative to the fixed blade automatically advances and cuts hairs without requiring manual intervention for each stroke, allowing users to clip their own hair efficiently.
2Reliability
If traditional hair scissors are used to cut split ends, then cutting can be performed, but the clipping effect is poor and split ends may not be completely cut off
Solution Approach 1:
The patent employs dynamic reciprocating motion of the movable blade holder, which moves back and forth relative to the fixed blade. This dynamic motion ensures that hairs are continuously advanced and cut, improving the reliability of the clipping effect. The eccentric mechanisms convert rotational motion into linear reciprocating motion, creating a sawing action that effectively cuts through hairs including split ends.
Solution Approach 2:
The cutting function is segmented into two independent components: a fixed blade for stability and a movable blade holder with reciprocating motion for cutting action. This segmentation allows each component to be optimized for its specific function, with the fixed blade providing a stable cutting edge and the movable blade providing the cutting motion, thereby improving overall clipping effectiveness.
3Productivity
If an electric hair clipper with reciprocating blade motion is designed, then clipping effectiveness is improved, but the device complexity increases
Solution Approach 1:
The patent merges the drive mechanism and the blade actuation mechanism into a single integrated system. The eccentric mechanisms serve dual purposes: they convert rotational motion from the motor into linear reciprocating motion for the movable blade holder, and simultaneously provide the cutting action. This merging of functions reduces the number of separate components needed, thereby managing device complexity while maintaining high productivity.
Solution Approach 2:
The patent transforms the rotational motion of the motor (circular dimension) into linear reciprocating motion of the blade (linear dimension) through eccentric mechanisms. This dimensional transformation allows the system to achieve complex reciprocating cutting motion from a simple rotational motor, improving productivity without proportionally increasing structural complexity.

Function Achieved in This Case
The electric hair clipper provides a convenient and effective solution for cutting split ends, with a compact design that is easy to use and maintain, and includes features like a hair storage bin and negative-ion generator for added functionality.
Implementation Method 1
The transmission member is fixedly provided with a first eccentric part and a second eccentric part. When the driving motor drives the transmission member to rotate, the first eccentric part drives the pressure lever to do linear reciprocating motion
Implementation Method 2
The second eccentric part drives the movable blade holder to do linear reciprocating motion to drive the movable blade to move for clipping

AI summary
An electric hair clipper is provided, which relates to the technical field of haircutting equipment. The electric hair clipper includes a cutting assembly, a driving assembly, and a fixing member and a sliding member that are convenient for mounting and removing a bin cover. The cutting assembly includes a bracket and a movable blade holder. The movable blade holder is movably arranged on the bracket. According to the electric hair clipper, when the driving motor works, hairs are pressed between the fixed blade and the movable blade and are clipped through cooperation between the movable blade and the fixed blade, so that the clipping effect is good. Cut hairs are stored in a hair storage bin. The electric hair clipper is easy to operate and convenient to use.
