Solution Overview

Problem

Conventional pressure gauges on air compressors suffer from inaccurate pressure value display due to the cylindrical body design, leading to reading errors and potential staining of the scale portion.

Innovation Solution

A transparent panel with marked scale portions on its internal face is used, allowing for clear viewing without user contact or staining, and featuring adjustable calibration units to ensure precise pressure value display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the scale portion is formed on the outer wall of a cylindrical body, then the pressure gauge can be manufactured with a simple cylindrical structure, but the pressure value cannot be viewed exactly due to the cylindrical body causing sight difference and reading error

Engineering Contradiction:
Improvecylindrical body structureVSAvoidpressure value reading accuracy
Core Design Contradiction:
Ease of manufactureVSMeasurement precision

Solution Approach 1:

The scale portion is separated from the cylindrical body and placed on a transparent panel. This segmentation allows the scale to be positioned on a flat surface (internal face of transparent panel) rather than on the curved outer wall of the cylindrical body, eliminating the sight difference caused by the cylindrical shape while maintaining manufacturing simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A transparent panel is introduced as an intermediary component between the user and the scale portion. The transparent panel provides a flat surface for marking the scale, allowing accurate viewing of pressure values while the panel itself can be positioned to avoid user contact and staining.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the scale portion is on the outer wall of the cylindrical body, then the structure is simple, but the scale portion is touched by users and becomes stained

Engineering Contradiction:
Improvestructure simplicityVSAvoidstaining of scale portion
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The scale portion is extracted from the outer wall of the cylindrical body and transferred to the internal face of a transparent panel. This extraction removes the scale from the user-contact area, preventing staining while maintaining structural simplicity through the use of a straightforward transparent panel component.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The scale portion is copied onto the transparent panel rather than being directly formed on the cylindrical body. This copying allows the scale to be positioned on a flat surface that is not subject to user contact, preventing staining while maintaining the functional integrity of the scale.

Inventive Principle:
Principle #26Copying

3Object-affected harmful factors

If the transparent panel is used with the scale on the internal face, then the scale portion is not touched and is not stained, but the device complexity increases

Engineering Contradiction:
Improvestaining resistanceVSAvoidtransparent panel with calibration units
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The transparent panel serves multiple functions: it provides a flat surface for accurate scale marking, acts as a protective barrier preventing user contact and staining, and incorporates calibration units for precise pressure value display. This multi-functionality justifies the additional component by consolidating several needs into a single element.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The scale portion and calibration units are merged onto the transparent panel as a single integrated component. This merging reduces the number of separate parts needed while achieving the goals of stain resistance and accurate display, thereby limiting the increase in device complexity.

Inventive Principle:
Principle #5Merging (Combining)
