Engine module unit for suction apparatus and suction apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor mounting solutions for suction devices are prone to unintentional motor displacement during maintenance, increased energy requirements due to reduced suction flow cross-section, and susceptibility to vibrations leading to loose connections.
Innovation Solution
A motor module unit comprising a suction motor module and a support module with a vertically extending motor receiving opening, featuring form-fitting holding means and a compact design to securely hold the motor in place while allowing optimal suction flow, made from thermoplastic for cost-effectiveness and enhanced mechanical resilience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reversibly lockable cover is used to secure the motor in place, then the motor can be securely held during operation, but the cover reduces the cross-section available for suction flow and increases energy consumption
Solution Approach 1:
The invention extracts the motor securing function from the cover and transfers it to the motor mounting plate through integrated retaining elements. The cover is removed entirely, eliminating the flow obstruction while the mounting plate's retaining elements provide secure motor fixation. This separates the securing function from the cover component, allowing the cover to be eliminated and the motor to be secured directly by the mounting plate structure.
2Reliability
If a reversibly lockable cover with screws is used to hold the motor, then the motor is securely fixed, but vibrations can cause the cover screws to loosen over time
Solution Approach 1:
The invention merges the motor securing function into the motor mounting plate itself through integrally formed retaining elements. Instead of using a separate cover with screws, the mounting plate directly provides retention features that secure the motor. This integration eliminates the separate covering component and its fastening elements, creating a more stable and vibration-resistant connection where the motor is held firmly by the mounting plate's own structure.
3Reliability
If the motor mounting structure is designed to securely hold the motor, then the motor remains in place during operation, but the available cross-section for suction flow is reduced
Solution Approach 1:
The invention applies local quality by designing the motor mounting plate with retaining elements that are strategically positioned only where needed for motor security. The retaining elements are located at the motor mounting opening edges, providing localized securing functionality. This allows the majority of the motor mounting opening to remain open and unobstructed, maximizing the suction flow cross-section while maintaining adequate motor support at critical locations.
