Washing Machine Motor Bracket Assembly for Vibration-Stable Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of washing machines is complicated due to the difficulty in positioning the motor bearing on the electric motor and the high vibrations during operation lead to noise issues and instability in the fixing of the motor to the washing tank.
Innovation Solution
A fixing bracket with a first arm and a second arm, featuring an assisted-insertion slot and a through hole, is designed to securely lock the central-axis electric motor to the washing tank, allowing for rapid and balanced fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the motor bearing is assembled on the electric motor and screwed to the fixing bracket, then the motor is fixed to the washing tank, but the assembly process becomes complex and time-consuming due to precise positioning requirements
Solution Approach 1:
The fixing bracket is segmented into multiple arms (first arm, second arm, third arm) that can independently engage with different parts of the motor, allowing simplified assembly without requiring precise positioning of a single complex bearing assembly
Solution Approach 2:
The fixing bracket acts as an intermediary component between the motor and the washing tank, providing multiple engagement points that simplify the assembly process while ensuring stable fixation
2Strength
If the motor is fixed using multiple screwing points on the fixing bracket, then the motor is securely attached, but high vibrations during operation cause noise and jeopardize the fixing
Solution Approach 1:
Different arms of the fixing bracket provide different types of engagement (screwing points, insertion slots, clamping mechanisms) tailored to specific locations, distributing vibration stresses locally and reducing overall noise
Solution Approach 2:
The fixing bracket design anticipates vibration effects by providing multiple engagement points and flexible arms that can absorb and dampen vibrational forces before they propagate to the motor and tank
3Reliability
If the motor bearing is precisely positioned in correspondence with screwing points, then secure fixing is achieved, but assembly difficulty increases due to positioning precision requirements
Solution Approach 1:
The fixing bracket is divided into multiple arms with different engagement mechanisms, allowing assembly workers to attach the motor at multiple separate locations rather than requiring precise positioning at a single point
Solution Approach 2:
The fixing bracket design allows the motor to essentially position itself through the multiple engagement points and flexible arms, reducing the skill and precision required from the assembler
