Solution Overview

Problem

Existing air pump connector heads require simultaneous manipulation of the valve, pump head, and handle positions, making operation inconvenient.

Innovation Solution

An air pump connector head design featuring a shell with a cavity, a tightening mechanism with elastomeric sealing rings, and a handle that allows single-handed operation through a pivotally connected limiting component and biasing component to control the sealing rings, enabling secure clamping and release of valves.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the pump head requires inserting a valve and lifting the handle to secure it, then the valve can be firmly clamped, but the operation becomes inconvenient requiring simultaneous manipulation of multiple components

Engineering Contradiction:
Improvevalve clamping reliabilityVSAvoidoperation convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The pump head automatically clamps the valve when the handle is inserted, without requiring manual manipulation of the valve or pump head. The system uses its own structure (handle insertion) to trigger the clamping action through the sealing ring deformation, making the operation self-service and eliminating the need for simultaneous manipulation of multiple components.

Inventive Principle:
Principle #25Self-service

2Reliability

If a traditional clamping mechanism is used, then the valve can be secured, but the device complexity increases with multiple components

Engineering Contradiction:
Improvevalve securing capabilityVSAvoidmechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses an elastomeric sealing ring (flexible element) instead of a rigid clamping mechanism with multiple components. The sealing ring deforms elastically to clamp the valve when the handle is inserted, providing reliable valve securing with a simple, single-component solution rather than a complex multi-part mechanism.

Inventive Principle:
Principle #30Flexible shells and thin films

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

Facilitates single-handed operation with secure clamping and release of valves, ensuring a tight seal and preventing leakage, with enhanced compatibility for different valve types and configurations.

Implementation Method 1

The at least one sealing ring is arranged between the stop section and the compressing plunger and is elastically deformable upon movement of the compressing plunger to clamp the valve

Methodology Applied
Scientific EffectElastic deformation: Elasticity

Implementation Method 2

A biasing component is arranged between the limiting component and the shell configured to bias the limiting component

Methodology Applied
Scientific EffectSpring force: Spring

AI summary

An air pump connector head comprises a shell (10, 10a) with a connecting end (11, 11a) and an operating end (12, 12a), housing a cavity (13, 13a). A stop section (15) is located at the connecting end. A tightening mechanism (20, 20a, 20c, 20d) includes at least one sealing ring (21, 21a, 21a', 21b, 21d, 21d') and a compressing plunger (22, 22a, 22b, 22d). The sealing ring(s) are positioned between the stop section (15) and the compressing plunger, capable of elastic deformation. A handle (30, 30a, 30b, 30c, 30d) features a joint section (31, 31a, 31b), an operation section (32, 32a), and a first locking section (33, 33a, 33b). The joint section is pivotally connected to the operating end and controls the compressing plunger. A limiting component (40, 40a, 40b, 40c, 40d) comprises a pressing section (42, 42a) and a second locking section (43, 43a, 43b) that engages detachably with the first locking section. A biasing component (50, 50a, 50b, 50c, 50d) is positioned between the limiting component and the shell.
