Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric trimming tools with vacuum attachment suffer from a narrowed negative pressure channel due to hose tangling during continuous rotation, leading to inefficient hair and debris collection, and have complex circuitry and high manufacturing costs.
Innovation Solution
A handheld electric pet trimming device with a 360-degree free-rotating adapter design, featuring a hose, adapter, and electric trimming tool, where the adapter includes connectors and a connecting pipe that allow for unhindered air flow through a 360-degree rotation mechanism, ensuring smooth hair and debris entry into the vacuum cleaner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the trimming tool is continuously rotated to achieve a comfortable trimming angle, then the ease of operation is improved, but the connecting hose becomes tangled and the negative pressure channel is narrowed
Solution Approach 1:
The adapter is designed to rotate 360 degrees relative to the hose connection, allowing the trimming tool to be positioned at any angle while maintaining a constant, untangled connection between the vacuum cleaner and the tool. This dynamic rotation capability enables continuous operation without hose tangling.
2Device complexity
If the trimming tool is powered by the vacuum cleaner, then the power supply is simplified, but the circuit structure becomes complicated and manufacturing cost increases
Solution Approach 1:
The power supply function is extracted from the vacuum cleaner and transferred to an independent rechargeable battery installed in the trimming tool. This allows the tool to operate independently without complex circuit connections to the vacuum cleaner, simplifying both the power supply structure and manufacturing process.
3Stability of the object's composition
If a fixed connection structure is used between the hose and adapter, then the structural stability is improved, but the rotation capability is limited and the negative pressure channel may be narrowed
Solution Approach 1:
The connection between the hose and adapter incorporates a rotating joint that maintains stable electrical and pneumatic connections while allowing 360-degree rotation. This dynamic connection preserves structural stability during operation while enabling full rotational freedom for comfortable trimming at any angle.

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 360-degree rotation design prevents hose tangling, ensuring efficient hair and debris collection while reducing circuit complexity and manufacturing costs by allowing wireless charging.
Implementation Method 1
when the vacuum cleaner creates a negative pressure, the hair and debris removed by the tool are absorbed into the vacuum cleaner through a negative pressure channel
Implementation Method 2
one end of the connecting pipe corresponding to the first connector is provided with at least one group of elastic arms, and the mounting buckles are arranged at the ends of the elastic arms
