Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If multiple vibration-proof members are provided inside the case, then vibration and noise are reduced, but the structure becomes complicated and assembly becomes difficult
Solution Approach 1:
The patent combines multiple separate vibration-proof members into a single integrated vibration-proof member that wraps around the electric pump unit. This single member performs the vibration isolation function that previously required multiple separate components, thereby simplifying the overall structure while maintaining effective vibration and noise reduction.
Solution Approach 2:
The single vibration-proof member serves multiple functions simultaneously: it acts as a vibration isolator, a structural support element, and a noise dampener. By consolidating these functions into one component, the patent reduces the number of parts needed while achieving the same or better performance in vibration and noise control.

3Device complexity
If a single vibration-proof member is used to wrap the electric pump unit, then structure is simplified and assembly is easier, but vibration and noise reduction effectiveness may be compromised
Solution Approach 1:
The vibration-proof member is designed to wrap around and enclose the electric pump unit, creating a nested configuration where the pump unit is contained within the vibration-proof structure. This wrapping arrangement ensures that vibration and noise are isolated from the case while maintaining structural simplicity and ease of assembly.
Solution Approach 2:
The vibration-proof member is made from elastic resin material that can flexibly conform to the shape of the electric pump unit while providing effective vibration isolation. This flexible material allows the single member to adapt to the pump's geometry and maintain contact across multiple surfaces, ensuring comprehensive vibration and noise reduction without requiring multiple rigid components.

AI summary
An air pump device includes an electric pump unit including a pump mechanism and a motor configured to drive the pump mechanism, a case housing the electric pump unit, and a vibration-proof member interposed between the electric pump unit and the case. The vibration-proof member is a plate-shaped member made of an elastic resin material and is wound around the electric pump unit to wrap the electric pump unit therein. A part of the vibration-proof member is sandwiched between the electric pump unit and one of facing surfaces that are inner surfaces of the case and face each other inside the case. Another part of the vibration-proof member is sandwiched between the electric pump unit and the other one of the facing surfaces.
