Pivoting Cutting Handle Layout for Better Clipper Operability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cutting devices, such as hair clippers, lack improved operability.
Innovation Solution
A cutting device with a main body comprising a first and a second main body portion connected via a coupling portion, where the second main body portion is elongated in a direction intersecting the first, allowing for improved grip and reduced overall length for enhanced usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the main body is made as a single elongated portion, then the structure is simple, but the operability is poor and the overall length is excessive
Solution Approach 1:
The main body is divided into a first main body portion and a second main body portion connected via a coupling portion. This segmentation allows the device to achieve improved operability through the ability to rotate or adjust the angle between portions, while maintaining relatively simple individual components that are easier to manufacture than a completely redesigning the entire structure as a single piece.
2Ease of operation
If the second main body portion is elongated in the first direction, then the structure is simple, but the overall length increases causing contact with user's shoulder
Solution Approach 1:
The second main body portion is elongated in a second direction that intersects with the first direction (the blade direction). This dimensional change allows the device to achieve a more compact overall length in the first direction, preventing contact with the user's shoulder, while still providing sufficient structure for improved operability through the coupling portion connection.
3Ease of operation
If the main body is divided into multiple portions, then the operability is improved, but the device complexity increases
Solution Approach 1:
The main body is divided into exactly two portions (first and second main body portions) connected by a coupling portion, providing the minimum necessary segmentation to improve grip and handling without creating excessive complexity. This limited segmentation allows users to grip different portions for different operating styles while keeping the number of parts manageable.
Solution Approach 2:
The coupling portion provides rotational or angular adjustment capability between the first and second main body portions, allowing the device to adapt to different user preferences and operating conditions. This dynamic feature improves operability without requiring multiple discrete adjustable components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances operability by facilitating easier handling and reducing the risk of accidental contact with the user's shoulder during use, while maintaining a balanced weight distribution and allowing for various gripping positions.
Implementation Method 1
the coupling portion includes a pivot shaft configured to rotate the second main body portion relative to the first main body portion
