Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If batteries and motor are arranged in axial stacking with batteries below motor, then mutual interference is avoided, but overall product length becomes large resulting in poor balance and instability
Solution Approach 1:
The patent transitions from axial stacking (one-dimensional arrangement) to radial/circumferential arrangement (two-dimensional arrangement). Multiple batteries are disposed circumferentially around the motor, changing the spatial dimension of component layout. This dimensional change reduces the axial length while improving balance and stability through symmetric weight distribution around the rotation axis.
Solution Approach 2:
The motor is positioned in the center with batteries nested circumferentially around it, creating a compact nested structure. The battery holder encompasses the motor, and batteries are arranged within this holder in a radial pattern, effectively nesting components to minimize overall dimensions while maintaining structural integrity.
2Ease of operation
If batteries and motor are arranged in axial stacking, then assembly is simplified, but excessive length makes the product inconvenient to carry
Solution Approach 1:
By arranging batteries circumferentially around the motor rather than stacking them axially, the patent reduces the overall length of the product. This radial arrangement maintains assembly simplicity while creating a more compact, carry-friendly form factor that does not extend excessively in any single direction.
3Volume of moving object
If batteries are spaced circumferentially on battery holder with motor surrounded by batteries, then internal space is fully utilized improving compactness, but structural complexity increases with multiple fixing brackets and columns
Solution Approach 1:
The battery holder is designed as a nested structure that encompasses the motor, with batteries arranged within the holder in a radial pattern. This nested arrangement efficiently utilizes the internal space, allowing batteries to surround the motor and maximize the use of available volume while maintaining a organized structural hierarchy.
Solution Approach 2:
The mounting structure is segmented into distinct functional components: the battery holder for circumferential battery arrangement, multiple fixing brackets for securing batteries at specific positions, and fixing columns for additional structural support. This segmentation allows each component to perform its specific function while collectively achieving compact space utilization.

AI summary
The present application provides a mounting structure and an air pump. The mounting structure comprises a battery holder and a device body. Several batteries are spaced circumferentially on the battery holder, and a first through-hole is provided axially in middle of the battery holder. A motor is provided axially in the device body, with one end extending through and out of the device body and the other end extending through the first through-hole, and at least partially surrounded by the several batteries. The air pump includes the mounting structure. The mounting structure and the air pump of the present application arrange the batteries circumferentially on the battery holder, improving the overall stability of the air pump. The motor is relatively surrounded by the batteries in a compact manner, fully utilizing the internal space and improving the convenience of carrying the air pump.
