Solution Overview

Problem

Conventional rotating closing devices for containers, such as bottles, face challenges in securely holding and centering bottles during the closing process, particularly with screw cap closures, due to limited torque absorption and potential tilting, which leads to incorrect closures and increased friction and grinding issues.

Innovation Solution

A rotating closing device with pivoting support segments that encompass a larger circumference of the bottle neck, providing enhanced stability and centering, eliminating the need for external guides and precise height adjustments, and incorporating anti-rotation devices to prevent bottle rotation during screwing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If spike elements or spike carriers are used to secure bottles against rotation, then torque absorption is improved, but the circumferential coverage is limited to a small area and cannot sufficiently hold bottles against tipping

Engineering Contradiction:
Improvetorque absorptionVSAvoidcircumferential coverage area
Core Design Contradiction:
ForceVSArea of stationary object

Solution Approach 1:

The support device is divided into multiple support segments (first support segment, second support segment, etc.) that can be distributed around the bottle circumference. Each segment independently provides torque absorption and support, collectively achieving 360-degree circumferential coverage while maintaining the torque absorption capability of individual spike elements.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If a fixed outer guide is added to support the bottle neck area, then bottle centering is improved, but friction losses and grinding effects increase

Engineering Contradiction:
Improvebottle centering precisionVSAvoidfriction losses
Core Design Contradiction:
Manufacturing precisionVSLoss of energy

Solution Approach 1:

The support segments are designed to be rotatable about vertical axes, allowing them to dynamically adapt to the bottle position and maintain optimal support without creating fixed friction points. This dynamic adjustment enables precise bottle centering while minimizing friction and grinding effects compared to fixed outer guides.

Inventive Principle:
Principle #15Dynamics

3Loss of energy

If the support surface of the outer guide is minimized to reduce friction, then friction losses are reduced, but the support and guidance effect is reduced

Engineering Contradiction:
Improvefriction lossesVSAvoidsupport and guidance effect
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

Each support segment is equipped with anti-twist devices (spikes, protrusions, or gripping elements) that provide localized high-friction contact points for reliable torque absorption and bottle holding. The combination of multiple localized support points around the circumference achieves both low overall friction and high support reliability.

Inventive Principle:
Principle #3Local quality

4Manufacturing precision

If precise height alignment of the outer guide support surface is performed, then bottle vertical orientation is improved, but adjustment time and operational complexity increase

Engineering Contradiction:
Improvebottle vertical orientationVSAvoidadjustment time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The rotatable support segments automatically self-align to the bottle neck as the bottle is placed on them, eliminating the need for manual height adjustment by operators. The segments' rotational freedom allows them to adapt to slight variations in bottle position and achieve proper vertical orientation automatically, significantly reducing adjustment time and operational complexity.

Inventive Principle:
Principle #25Self-service
