Long-Rod Electric Tool with Adjustable Operating Unit Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Long-rod-type electric tools have poor manoeuvrability due to the operating unit being relatively far away from the user, necessitating a solution to adjust the orientation of the operating unit.
Innovation Solution
A long-rod-type electric tool is designed with a handle assembly, a machine head assembly, and a long rod assembly, featuring at least one interface that allows the orientation of the operating unit to be adjusted in at least one degree of freedom.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a long rod assembly is provided to enable remote operation, then the user can operate the tool from a distance and reduce waist fatigue, but the operating unit becomes far from the user resulting in poor manoeuvrability
Solution Approach 1:
The patent applies the dynamics principle by making the long rod assembly adjustable in length and the operating unit adjustable in orientation. The long rod assembly can be extended or retracted, and the operating unit can be pivoted to different angles, allowing the system to adapt to different working conditions and maintain good manoeuvrability even at extended distances from the user.
2Adaptability or versatility
If a fixed orientation operating unit is used, then the structure is simple, but the adaptability to different working conditions is poor
Solution Approach 1:
The patent implements dynamics by providing an operating unit that can be adjusted to different orientations and positions. The operating unit is capable of pivoting relative to the long rod assembly, allowing it to adapt to various working conditions such as different angles of operation, different reach distances, and different operational positions, thereby significantly improving versatility.
