Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting devices, such as hair clippers, suffer from poor operability.
Innovation Solution
A hair clipper design featuring a main body with two interconnected main body portions, one elongated in the vertical direction and the other in the horizontal direction, allowing for improved grip and reduced length, along with a pivot shaft for rotating the second main body portion relative to the first, enhancing usability and grip stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the main body is designed as a single elongated portion, then the device structure is simple, but the operability and grip stability are poor
Solution Approach 1:
The main body is divided into two distinct main body portions (first main body portion and second main body portion) that are elongated in different directions. This segmentation allows each portion to contribute differently to the overall functionality, with the first portion providing a stable base and the second portion extending the operational reach, thereby improving operability while maintaining reasonable structural complexity
Solution Approach 2:
The second main body portion is elongated in a second direction that intersects with the first direction of the first main body portion. This dimensional change creates a multi-directional structure that improves grip stability and operability by distributing the device's mass and functional elements across different spatial orientations, allowing for better handling and control
2Length of moving object
If the overall length of the device is reduced, then the handling and grip become easier, but the functional components may become cramped
Solution Approach 1:
By extending the second main body portion in a direction intersecting with the first main body portion, the device effectively increases its functional volume without proportionally increasing its overall length. This multi-directional arrangement allows functional components to be distributed more efficiently across the available space, accommodating necessary components while maintaining a compact form factor for easier handling
3Adaptability or versatility
If the second main body portion is made rotatable, then the versatility and gripping positions are enhanced, but the mechanism complexity increases
Solution Approach 1:
The rotatable coupling portion is designed to allow the second main body portion to be rotated and fixed at predetermined angular positions. This preliminary positioning capability enables users to select optimal gripping positions before use, enhancing versatility without requiring complex continuous adjustment mechanisms. The rotation is constrained to specific positions, simplifying the mechanism while achieving the desired adaptability
