Portable Air Pump Biasable Pressure Gauge Pivot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable air pumps are inefficient due to the need for two-handed operation, leading to user fatigue, and the pressure gauge is difficult to read when used as a floor pump, as the mirror-based solution for viewing pressure gauge readings is inconvenient.
Innovation Solution
A portable air pump design featuring a biasable pressure gauge with a beveled face and pivot shaft, allowing the gauge to be positioned perpendicularly or quasi-perpendicularly for easy reading, and a supplementary member that acts as a footplate for stable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pressure gauge is installed in the pump body and the pump body is kept vertical against the floor, then the structure is compact, but the user cannot view the readings of the pressure gauge
Solution Approach 1:
The pressure gauge is made movable relative to the pump body through a pivot shaft connection. The gauge can rotate between a first position (aligned with the pump body axis) and a second position (perpendicular to the pump body), allowing dynamic adjustment of the viewing angle to facilitate reading while maintaining structural integration.
2Ease of operation
If a mirror-based pressure gauge cover is used to reflect readings, then the gauge can be viewed from different angles, but the cover must be kept at a sharp angle (e.g., 45 degrees) which causes user inconvenience
Solution Approach 1:
The pressure gauge is extracted from the fixed position in the pump body and placed on a movable biasing member. This eliminates the need for a mirror-based viewing system and allows the gauge to be directly viewed from multiple angles through its own movement, simplifying the overall structure.
3Adaptability or versatility
If the pump body bottom surface area is limited with a foldable footplate, then the pump remains portable, but the structure is unsteady and may vibrate during operation
Solution Approach 1:
The biasing member is designed to be movable between a received position (aligned with the pump body) and an extended position (perpendicular to the pump body). When extended, it provides additional support to enhance stability during floor-type operation, while when retracted, it maintains portability. This dynamic adjustment allows the structure to adapt to different operational requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances operational stability and facilitates easy reading of pressure gauge readings, reducing user effort and improving the stability and usability of the air pump when used as both a handheld and floor-type pump.
Implementation Method 1
a biasing member having a beveled face and a pivot hole located on the beveled face and coupled with the pivot shaft of the head member in such a manner that the biasing member is biasable relative to the head member between a received position where the biasing member is kept in axial alignment with the portable air pump and an extended position where the biasing member is kept in a perpendicular or quasi-perpendicular position relative to the portable air pump
