Suspended Air Pump Mounting for Vibration and PCB Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pumps used in air beds generate noise due to vibration during operation, which can disrupt users, especially during sleep, and may damage internal components like printed circuit boards.
Innovation Solution
The pump is suspended within a housing using elongated, resilient connectors that reduce vibration transmission, and stop mechanisms are employed to prevent contact with the printed circuit board, thereby minimizing noise and protecting components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pump is rigidly mounted to the housing, then structural stability is improved, but vibration noise increases and electronic components may be damaged
Solution Approach 1:
The patent introduces resilient connectors as intermediary elements between the pump and housing. These connectors serve as mediators that transmit necessary mechanical support while filtering out harmful vibrations. The resilient material absorbs vibrational energy, preventing it from propagating to the housing and electronic components, thus resolving the contradiction between structural stability and vibration noise reduction.
Solution Approach 2:
The patent extracts the pump from direct rigid contact with the housing by suspending it through resilient connectors. This separation removes the source of vibration noise from the housing structure, allowing the pump to operate independently while still maintaining positional stability through the elastic properties of the connectors.
2Reliability
If the pump is rigidly mounted to the housing, then structural stability is improved, but electronic components may be damaged from excessive pump movement
Solution Approach 1:
The resilient connectors act as protective intermediaries that isolate the electronic components from the pump's excessive movements and vibrations. By absorbing mechanical shocks and limiting movement amplitude, these connectors prevent direct contact between the pump and fragile electronic components, ensuring both structural stability and component protection.
Solution Approach 2:
The patent employs resilient connectors that provide beforehand cushioning for the electronic components. These connectors are pre-configured to absorb and dampen vibrations before they can reach the electronic components, creating a protective buffer zone that prevents potential damage from excessive pump movement during operation.
3Object-affected harmful factors
If resilient connectors are used to suspend the pump, then vibration noise is reduced, but device complexity increases
Solution Approach 1:
The patent utilizes flexible resilient connectors that can be manufactured as thin, elastic elements. These flexible connectors provide vibration isolation functionality while maintaining a compact and relatively simple structure. The elastic properties of these thin-film-like connectors enable effective vibration damping without requiring complex mechanical assemblies.
