Inflator Upper Cover Pressure Display for Easier Reading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inflators, particularly floor-standing ones, have pressure gauges located at the base, making it difficult for users to accurately read the pressure value without interrupting the inflating action, leading to potential errors.
Innovation Solution
Integrating a pressure display unit in the upper cover of the inflator, using a push rod as an axis for arc-shaped pressure indication, with a piston-driven gear mechanism to directly show pressure changes on a numerical display panel in the upper cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pressure gauge is located at the base of the inflator, then the device structure is simplified, but the user cannot accurately observe the pressure value without interrupting the inflating action
Solution Approach 1:
The pressure display unit is moved from the horizontal base plane to the vertical upper cover surface, changing the spatial dimension of the pressure gauge location. This vertical relocation places the pressure display within the user's natural line of sight during the inflating action, eliminating the need to interrupt or lean down to read the pressure value.
2Volume of stationary object
If the pressure gauge is located at the base, then the overall device volume is reduced, but the user needs to get closer to the pressure gauge to read the value accurately
Solution Approach 1:
By relocating the pressure display unit to the upper cover's vertical surface, the design maintains compact horizontal dimensions while creating vertical space for an easily observable display. The pressure gauge is positioned at eye level, allowing users to read the pressure value from a comfortable distance without leaning forward or getting closer.
3Ease of operation
If the pressure display unit is integrated in the upper cover, then the user can easily observe pressure changes, but the device structure becomes more complex
Solution Approach 1:
The pressure display unit is integrated directly into the upper cover structure, merging the display function with the housing component. This consolidation eliminates the need for separate mounting brackets or additional structural elements, achieving easy observability while minimizing the increase in overall device complexity.
