Handheld Cleaner Terminal Assembly for Simplified Wire Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handy cleaners face challenges in assembling due to the difficulty in combining PCBs and connecting wires, especially given their small volume and the need for separate power and control signal wires.
Innovation Solution
A cleaner design that includes a suction unit, a main body with a dust separation unit, and a handle unit, where the power and control signal wires are separated and connected through terminals, allowing for easy assembly without manual connection, with the handle unit sliding-coupled to the main body and mechanically connected to the main body terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaner is designed with separate power supply wire and control signal wire, then the functionality is improved, but the assembly complexity increases
Solution Approach 1:
The patent separates the power supply function and control signal function into distinct wires (power supply wire and control signal wire), allowing independent routing and connection. This segmentation enables the cleaner to maintain full functionality while simplifying the assembly process, as each wire can be connected to its corresponding terminal independently without interfering with the other connection.
Solution Approach 2:
The patent introduces terminals as intermediary connection points between the wires and the motor/PCB. The terminals serve as mediators that facilitate easy connection and disconnection of the separate power and control wires, reducing assembly complexity by providing standardized connection interfaces rather than requiring direct wire-to-component soldering.
2Volume of moving object
If the cleaner volume is reduced to make it handy, then the portability is improved, but the ease of assembly deteriorates
Solution Approach 1:
The patent employs a slide-coupling mechanism for the handle unit that allows dynamic assembly and disassembly. The handle unit can be easily slide-coupled to the main body, providing a simple assembly process that does not require complex manual wiring operations, thus maintaining ease of assembly despite the reduced handy size of the cleaner.
3Ease of manufacture
If the terminals are used to connect wires, then the assembly ease is improved, but the terminal size increases
Solution Approach 1:
The patent designs the terminals to be nested within or integrated into the handle unit and main body structure. The terminals are positioned such that they are contained within the existing housing spaces, minimizing additional volume while still providing the necessary connection functionality for the separate power and control wires.

AI summary
A cleaner includes: a suction unit that guides dust and air; a main body that includes a dust separation unit for separating dust from air guided through the suction unit; a main body terminal mounted on the main body; a handle unit that is slide-coupled to the main body; and a handle terminal mounted on the handle unit and is connected to the main body terminal when the handle unit is slide-coupled to the main body.
