Motor bracket for a household appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric motor arrangements in household appliances are difficult to assemble and disassemble, requiring disassembly of the air channel and multiple housing elements, which complicates repairs and maintenance.
Innovation Solution
A motor bracket with a disc-shaped or ring-shaped structure, featuring openings for easy connection and disconnection, allows the motor to be attached from one side and positioned outside the fluid channel, using fastening means like screws, straps, or clips, with integrated seals to maintain a fluid-tight seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the motor is integrated into the air channel with multiple housing elements, then the motor can be positioned inside the fluid channel to drive fan wheels or pump impellers, but the assembly and disassembly process becomes complex and time-consuming
Solution Approach 1:
The motor bracket is designed as a separate, segmented component that can be independently attached to the housing and motor. This segmentation allows the motor bracket to be removed as a single unit, simplifying assembly and disassembly operations without requiring disassembly of multiple housing elements.
Solution Approach 2:
The motor bracket extracts the motor mounting function from the integrated housing structure. By providing a dedicated bracket that can be attached to the housing and the motor separately, the design enables easy removal of the motor assembly from the air channel without disrupting the housing structure.
2Reliability
If the motor is positioned inside the fluid channel, then the drive shaft can directly drive fan wheels or pump impellers, but the motor becomes vulnerable to moisture and fluid damage
Solution Approach 1:
The motor bracket acts as an intermediary component between the motor and the air channel environment. It provides a mounting interface that allows the motor to be positioned optimally while protecting it from direct exposure to moisture and fluid damage in the air channel.
Solution Approach 2:
The motor bracket enables the motor to be mounted in a different spatial dimension relative to the air channel, allowing the drive shaft to extend through the bracket into the air channel without the motor body being exposed to the harsh environment. This dimensional repositioning protects the motor while maintaining drive functionality.
3Ease of repair
If multiple fastening elements and housing components are used to secure the motor, then the motor can be firmly fixed in position, but the repair process becomes more difficult and time-consuming
Solution Approach 1:
The motor bracket is designed as a separate segment that consolidates the fastening function. Instead of using multiple fastening elements distributed across the housing, all fixation is achieved through the single motor bracket component, which can be quickly removed for motor replacement while maintaining strong fixation during operation.
