Detachable Motor Module for Blower Assembly Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited lifespan of electrical motors in air blower assemblies for tubs and hand dryers leads to frequent replacements, which are cumbersome and time-consuming due to the need to disconnect them from power and pneumatic systems, often in hard-to-reach locations.
Innovation Solution
A modular blower assembly design where the motor module is detachably secured to a heating module, allowing for easy replacement of the motor without disconnecting from the power source, using a wireless connection system with electrical connectors for secure and efficient maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the motor is integrated into a fixed blower assembly, then the structural integrity and stability are improved, but the ease of repair deteriorates due to cumbersome replacement procedures
Solution Approach 1:
The blower assembly is divided into separate modules: a fixed housing module and a detachable motor module. The motor module can be independently removed and replaced without affecting the housing or requiring disconnection from power and pneumatic systems, thus maintaining structural integrity while significantly improving ease of repair.
2Ease of repair
If the motor module is detachably secured, then the ease of repair is improved, but the device complexity increases due to additional connection interfaces
Solution Approach 1:
The electrical connector and pneumatic connector are integrated into a single motor module assembly. This merging of multiple connection functions into one detachable unit simplifies the replacement process, as the user needs to handle only one module rather than multiple separate connections, thereby reducing operational complexity despite adding a modular interface.
3Loss of time
If the motor remains connected to power source during replacement, then the loss of time is reduced, but the safety risks increase due to electrical hazards
Solution Approach 1:
The motor module is extracted as a self-contained unit with its own integrated electrical connector. This allows the motor to be replaced without disconnecting the main power source from the housing, as the electrical connection is contained within the detachable module. The power source remains connected to the housing throughout the replacement process, eliminating the need for power disconnection and associated safety risks.

AI summary
A blower assembly for a tub, a hand dryer, etc, may include a first module securable to a structure, the first module defining one of an air inlet and an air outlet. A second module defining the other of the air inlet and the air outlet, the second module including a motor, the motor drivingly engaged to a blower to, in use, drive an air flow from the air inlet to the air outlet. The second module is detachably securable to the first module such that the second module is secured to the structure via the first module.
