Handy 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 to supply power and control signals to the motor.
Innovation Solution
A cleaner design that separates power and control signal wires, using a main body terminal and a handle terminal that connect mechanically when the handle unit is coupled to the main body, allowing for easy assembly without manual connection of terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the battery is connected to the motor through power supply wires and control signal wires in the handle, then power and control signals can be supplied to the motor, but the assembly process becomes complex and difficult due to the small volume of handy cleaners
Solution Approach 1:
The patent divides the wire connections into separate segments: power supply wires are routed through the body to connect the battery and motor, while control signal wires are integrated into the PCB located in the handle. This segmentation allows each type of connection to be managed independently, simplifying the assembly process despite the device's compact size.
Solution Approach 2:
The PCB acts as an intermediary component that receives control signals from the handle and transmits them to the motor through the body. This intermediary structure consolidates multiple control connections into a single integrated component, reducing the complexity of wire management during assembly.
2Volume of moving object
If the cleaner is designed with small volume, then portability is improved, but the PCB and wire connections become difficult to combine and assemble
Solution Approach 1:
The handle unit is nested within the overall cleaner structure, with the PCB integrated into the handle's internal space. The power supply wires and control signal wires are routed through existing structural pathways within the compact design, allowing connections to be made without increasing the external volume of the device.
Solution Approach 2:
The patent utilizes the three-dimensional space within the handle and body efficiently by routing wires along structural elements and using vertical stacking of components. This dimensional approach allows multiple connections to be made within the limited volume without compromising assembly ease.
