Solution Overview

Problem

Existing bottle processing solutions, whether industrial or manual, face challenges in terms of hygiene, productivity, and environmental impact due to their scale and the need for transportation, especially in establishments like hotels and restaurants that require compact, cost-effective, and hygienic bottle reuse systems.

Innovation Solution

A compact bottle processing device with an automated conveying unit, gripping arms, and stations for cleaning, filling, and capping, designed to operate within a closed circuit of less than 20m, ensuring minimal human intervention and integration into existing facilities, with features like rotating handles for bottle orientation and a protective enclosure for hygiene.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If industrial-scale bottling lines are used, then productivity and hygiene level are improved, but device complexity and space requirements increase significantly

Engineering Contradiction:
Improvebottle processing throughputVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The device is divided into modular functional stations (washing station, filling station, capping station) arranged along a compact closed-loop conveyor circuit. Each station performs a specific function independently, allowing the system to achieve industrial-level automation without requiring a massive integrated facility. The segmentation enables the complex process to be broken down into manageable, space-efficient components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs a closed-loop conveyor system where bottles are transported vertically and horizontally through compact routing. The conveyor unit creates a three-dimensional processing path that fits within a small footprint, effectively using vertical space and optimized routing to reduce the horizontal area required compared to traditional linear bottling lines.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If industrial-scale bottling lines are used, then hygiene level is improved, but area occupied increases to several hundred or thousands of square meters

Engineering Contradiction:
Improvehygiene levelVSAvoidfacility area
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

Multiple processing functions (washing, filling, capping) that would traditionally require separate rooms or large facility areas are merged into a single integrated compact device. The closed-loop conveyor brings all stations into close proximity, allowing the entire bottling process to occur within a small footprint while maintaining industrial hygiene standards through automated enclosed processing.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system uses vertical arrangement and compact routing of the closed-loop conveyor to accommodate multiple processing stations in a limited horizontal area. By utilizing three-dimensional space efficiently, the device achieves industrial-scale hygiene and automation without requiring hundreds of square meters of facility space.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Area of stationary object

If manual workshops are used, then space requirements are reduced, but hygiene level and productivity decrease due to manual handling

Engineering Contradiction:
Improvefacility areaVSAvoidhygiene level
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The device enables bottles to be processed automatically through the closed-loop system without manual intervention between stations. The automated conveying and processing eliminate the need for human handlers, ensuring consistent hygiene levels comparable to industrial facilities while maintaining a compact footprint suitable for small establishments.

Inventive Principle:
Principle #25Self-service

4Ease of manufacture

If glass bottles are transported from external sources, then local production capability is reduced, but transport costs and environmental impact increase due to weight

Engineering Contradiction:
Improvelocal bottle production capabilityVSAvoidtransport weight
Core Design Contradiction:
Ease of manufactureVSWeight of moving object

Solution Approach 1:

The compact device serves multiple functions: it can process both returned glass bottles and new bottles, handle washing, filling, and capping operations, and adapt to different bottle types. This multi-functionality allows establishments to implement complete local bottle processing without requiring separate equipment for each function, making local production viable even for small operations.

Inventive Principle:
Principle #6Universality (Multi-functionality)
