Solution Overview

Problem

Reusable plastic bottles in beverage bottling plants often shift during cleaning, disrupting the alignment of the spray nozzle and bottle mouth, leading to inconsistent interior cleaning due to existing holding devices that apply mechanical stress and require manual intervention for opening and closing.

Innovation Solution

A device with a pivotable locking lever that can transition between locking and removal positions, allowing for secure and gentle container handling without manual access into the container cell, utilizing a locking mechanism with complementary elements for reliable and low-maintenance operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If spring-loaded bottle holders are used to hold plastic bottles in the container cell, then the bottles can be secured in position, but mechanical stress is applied to the bottles and manual intervention is required to open and close the holders

Engineering Contradiction:
Improveholding stabilityVSAvoidoperation simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The locking lever is designed to be movable between a locked position (where it engages with the bottle) and an unlocked position (where it releases the bottle). This dynamic mechanism allows automatic locking during insertion and easy unlocking by moving the lever, eliminating the need for manual intervention while maintaining holding stability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The locking lever automatically engages with the bottle when it is inserted into the container cell, providing self-locking functionality. The lever's design allows it to snap into place without requiring manual operation, and it can be easily disengaged by simple lever movement, making the system self-servicing.

Inventive Principle:
Principle #25Self-service

2Reliability

If resilient locking devices are used to secure plastic bottles, then the bottles can be held firmly, but mechanical stress is placed on the bottle mouth area during insertion

Engineering Contradiction:
Improvelocking reliabilityVSAvoidmechanical stress on bottle
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The locking lever transitions from a retracted position during insertion to an engaged position after insertion is complete. This dynamic sequence ensures the bottle is not stressed during insertion, and only after the bottle is safely in place does the lever engage to provide secure locking.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The bottle is first inserted into the container cell in a state where the locking lever is not engaged, avoiding mechanical stress during insertion. Only after the bottle is properly positioned does the locking lever engage to secure it, separating the insertion and locking actions.

Inventive Principle:
Principle #10Preliminary action

3Extent of automation

If the locking device requires manual access into the container cell to open and close, then the locking mechanism can be directly controlled, but the operation becomes complex and time-consuming

Engineering Contradiction:
Improveautomatic lockingVSAvoidtime for opening and closing
Core Design Contradiction:
Extent of automationVSLoss of time

Solution Approach 1:

The locking lever automatically engages with the bottle during insertion without requiring manual intervention. The design allows the lever to snap into the locked position automatically, and unlocking can be achieved by simple external manipulation of the lever, eliminating the need for manual access into the container cell.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The locking lever is positioned and operated from outside the container cell, extracting the control mechanism from the interior space. This allows operators to lock and unlock bottles without reaching into the container cell, simplifying operation and reducing time.

Inventive Principle:
Principle #2Taking out (Extraction)
