Vertical PCB Layout in Cordless Cleaner to Minimize Wiring Complexity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaners face issues with elongated and complex wiring between the suction motor and printed circuit board, as well as between the battery and the printed circuit board, leading to increased weight, resistance, and assembly complexity, which degrades product competitiveness and efficiency.
Innovation Solution
The cleaner design minimizes wiring by positioning the printed circuit board in upward and downward directions between the main body and handle housings, with direct connections to the suction motor and battery, and incorporates a handle housing that allows for detachable battery coupling, reducing the need for elongated connections and complex wiring structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the printed circuit board is disposed on the inside of the main body housing, then the size of the printed circuit board is reduced, but the wiring length to peripheral parts is elongated and the degree of integration increases causing heat generation
Solution Approach 1:
The printed circuit board is repositioned from a horizontal arrangement inside the main body housing to a vertical arrangement along the longitudinal axis, extending from the main body housing into the handle housing. This dimensional change allows the board to maintain compact footprint while reducing wiring length to peripheral components located along the vertical axis.
2Area of stationary object
If the printed circuit board is disposed on the inside of the main body housing, then the board size is reduced, but the resistance due to connector wiring increases and efficiency is degraded
Solution Approach 1:
By repositioning the printed circuit board vertically along the longitudinal axis of the cleaner, the physical distance to peripheral parts such as the suction motor and battery is reduced. This spatial reconfiguration minimizes wiring length and consequently reduces electrical resistance and energy loss in the connector wiring.
3Area of stationary object
If the printed circuit board is disposed on the inside of the main body housing, then the board size is reduced, but the overall weight of the cleaner increases due to complex wiring
Solution Approach 1:
The vertical arrangement of the printed circuit board along the longitudinal axis reduces the amount of wiring required to connect peripheral components. This reduction in wiring material directly decreases the overall weight of the cleaner while maintaining the compact board design.
4Area of stationary object
If the printed circuit board is disposed on the inside of the main body housing, then the board size is reduced, but the assembly process becomes complicated
Solution Approach 1:
By positioning the printed circuit board vertically along the longitudinal axis of the cleaner, the assembly process is simplified. This orientation allows for more straightforward routing of wiring harnesses and easier access during assembly operations, reducing manufacturing complexity compared to horizontal arrangements inside the main body housing.
