Solution Overview

Problem

Existing capping apparatuses can deform caps due to the use of balls or pressing means, and are not adaptable to varying environmental conditions, leading to potential damage and inefficiencies in capping operations.

Innovation Solution

The apparatus employs air suction means for removable retention of caps, along with motorized control and actuation systems to manage axial and rotational movements, allowing for adjustable capping parameters independent of rotation speed and production speed, and incorporating temperature measurement for dynamic operation adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If balls or pressing means are used for cap retention, then the cap can be securely held during screwing, but the cap may be deformed causing application problems

Engineering Contradiction:
Improvecap retention reliabilityVSAvoidcap shape precision
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent replaces the mechanical ball-and-elastic-ring retention system with a suction-based retention system. The grip element incorporates a suction cup that uses vacuum pressure to hold the cap securely during the screwing operation, eliminating the deforming mechanical pressure of balls while maintaining reliable retention.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces pneumatic principles by using a suction cup mechanism controlled by vacuum pressure. The suction cup can be actuated to create a vacuum that securely holds the cap without mechanical contact pressure, and can be released by equalizing pressure, providing reliable yet non-deforming retention throughout the capping cycle.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Adaptability or versatility

If fixed operating parameters are used in capping apparatus, then the machine structure is simple, but the apparatus cannot adapt to different environmental conditions

Engineering Contradiction:
Improveenvironmental condition adaptabilityVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic adjustability of operating parameters including suction pressure, screwing speed, and axial thrust. These parameters can be modified in real-time based on environmental conditions and cap characteristics, allowing the apparatus to adapt to varying conditions while maintaining optimal performance through programmable control.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent enables changeable operating parameters such as vacuum pressure levels, rotational speed, and axial force that can be adjusted according to different environmental conditions and cap types. This allows the same apparatus to handle various conditions by modifying parameters rather than requiring different mechanical configurations.

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If mechanical retention means are used, then the structure is simple, but the caps with reduced weight and thickness are deformed

Engineering Contradiction:
Improveretention system simplicityVSAvoidcap integrity
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent replaces simple mechanical retention elements like balls and springs with a suction-based system that uses vacuum pressure. This maintains relative simplicity in structure while dramatically improving cap handling by eliminating localized mechanical pressure points that deform thin-walled caps.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses pneumatic pressure distribution through the suction cup to hold caps uniformly without concentrated mechanical forces. The vacuum pressure acts distributed across the cap surface rather than through discrete contact points, preventing deformation of lightweight caps while maintaining secure retention.

Inventive Principle:
Principle #29Pneumatics and hydraulics
