Piston pump device

Solution Overview

Problem

Existing oscillating piston pump devices face limitations in flexibility and component size, often requiring additional components like adapters that increase costs and can negatively impact pump performance and fluid pressure.

Innovation Solution

An oscillating piston pump device with a compression chamber housing and fluid channel having a bend, where the piston unit includes a piston with a piston body and extension, and the compression chamber housing is integrated with the pump housing, reducing component length and eliminating the need for additional components, thereby enhancing flexibility and installation options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If additional components like adapters are used to connect the compression chamber housing, then the device can be assembled, but the component size increases and costs increase

Engineering Contradiction:

Improveassembly capabilityVSAvoidcomponent length

Core Design Contradiction:

Ease of manufactureVSLength of stationary object

Solution Approach 1:

The fluid channel is integrated directly into the compression chamber housing, merging two previously separate components (housing and fluid channel) into a single unit. This eliminates the need for additional adapters or connectors, reducing overall component length while maintaining assembly capability.

Inventive Principle:

Principle #5Merging (Combining)

2Ease of manufacture

If additional components like adapters are used to connect the compression chamber housing, then the device can be assembled, but manufacturing costs increase
