Solution Overview

Problem

Existing packing bell inserts for bottles suffer from dimensional instability and uneven deformation under compressed air, leading to potential damage to bottles and the inability to integrate an ejection mechanism due to complex geometry and high overall height of the pressure piston.

Innovation Solution

A packing bell insert with a dimensionally stable stiffening element connected to the pressure piston, which ensures uniform force transmission to the gripping part, allowing for compact dimensions and the integration of an ejection mechanism through a through-opening in the pressure piston.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the pressure piston is designed with ribs or projections to maintain stability, then the pressure piston remains sufficiently stable under compressed air, but the overall height becomes relatively large and the geometry becomes complex, preventing integration of an ejection mechanism

Engineering Contradiction:
Improvestability of pressure pistonVSAvoidgeometry of pressure piston
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The pressure piston is divided into two separate components: a cylindrical pressure piston body and a separate stiffening element with ribs. This segmentation allows the pressure piston to maintain stability through the stiffening element while keeping the overall geometry simple and compact, enabling integration of an ejection mechanism through the cylindrical body.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The stiffening element acts as an intermediary component that provides structural stability to the pressure piston without being integral to it. This mediator component allows the pressure piston to maintain its shape under compressed air while keeping the overall design simple and compact.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the pressure piston has a relatively large overall height to maintain stability, then the pressure piston remains sufficiently stable under compressed air, but the packing bell insert becomes less compact

Engineering Contradiction:
Improvestability of pressure pistonVSAvoidoverall height of packing bell insert
Core Design Contradiction:
Stability of the object's compositionVSLength of moving object

Solution Approach 1:

By segmenting the pressure piston into a cylindrical body and a separate stiffening element, the design eliminates the need for excessive height in the pressure piston body. The stiffening element provides stability without increasing the overall height, enabling a compact packing bell insert design.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the pressure piston is deformed axially under compressed air to grip the bottle neck, then the gripping part deforms to encompass the bottleneck, but uneven deformation occurs leading to potential damage to bottles

Engineering Contradiction:
Improvegripping capabilityVSAvoiduniformity of deformation
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The stiffening element serves as an intermediary that ensures uniform deformation of the gripping part. It distributes the axial force from compressed air evenly across the gripping part, preventing localized stress concentrations and potential damage to the bottle neck during gripping.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Stability of the object's composition

If the pressure piston is designed with integral ribs to maintain shape, then the pressure piston retains its shape under pressure, but manufacturing tolerances cause twisting or tilting instead of even deformation

Engineering Contradiction:
Improveshape retention of pressure pistonVSAvoidevenness of deformation
Core Design Contradiction:
Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

Separating the pressure piston from the stiffening element allows each component to be manufactured independently with standard tolerances. The stiffening element is added afterward to provide shape retention, eliminating the twisting and tilting issues that occur when ribs are integral to the pressure piston.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pressure piston combines a cylindrical body with a separate stiffening element to create a composite structure. This composite design provides shape retention while allowing for even deformation under pressure, as the stiffening element can be precisely positioned to distribute forces uniformly.

Inventive Principle:
Principle #40Composite materials
