Solution Overview

Problem

Existing robotic unscramblers struggle to achieve 100% efficiency in handling and positioning bottle containers with non-symmetric shapes and offset necks, due to the need for additional rotation operations and recirculation of non-processed containers.

Innovation Solution

A robotic unscrambler system that includes a product picking area, a transfer conveyor, and a product unscrambling device with selectively routable carriers and paths, allowing for the unscrambling of containers regardless of their initial orientation, and incorporating buffer areas to manage fluctuations in feed rate.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If handling robots process containers with predetermined side orientation, then processing reliability is improved, but productivity decreases due to recirculation requirements

Engineering Contradiction:
Improveprocessing reliabilityVSAvoidproductivity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies asymmetry by designing the container carrier with a specific orientation (longitudinal axis alignment) that matches the asymmetric geometry of the containers. The carrier's longitudinal axis is aligned with the container's longitudinal axis, and the carrier's transverse axis is aligned with the container's transverse axis, creating an asymmetric relationship that eliminates the need for recirculation while maintaining reliable processing.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The patent inverts the traditional approach by allowing containers to be processed in any initial orientation (scrambled state) rather than requiring predetermined side-up orientation. The unscrambling device actively reorients containers to the correct orientation during processing, reversing the conventional logic where containers must arrive pre-oriented.

Inventive Principle:
Principle #13The other way round (Inversion)

2Manufacturing precision

If additional rotation operations are performed to correct container orientation, then manufacturing precision is improved, but processing time increases

Engineering Contradiction:
Improvecontainer orientation precisionVSAvoidprocessing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by performing the unscrambling operation (rotating containers to correct orientation) as part of the initial processing sequence rather than as a corrective step later. The unscrambling device is integrated into the processing line and performs orientation correction before containers proceed to subsequent operations, eliminating delays.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent ensures continuity of useful action by designing the unscrambling device to process containers continuously as they move through the system. The selective routing mechanism directs containers to appropriate unscrambling paths without interrupting the overall flow, maintaining continuous processing while achieving precise orientation.

Inventive Principle:
Principle #20Continuity of useful action

3Adaptability or versatility

If recirculation path is implemented to handle non-processed containers, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improvehandling versatilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the unscrambling function from the main processing line by implementing a separate unscrambling device with selective routing. Containers that require orientation correction are diverted to the unscrambling device, processed, and then returned to the main line. This separation eliminates the need for complex recirculation paths while maintaining adaptability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an intermediary unscrambling device that acts as a mediator between the scrambled container input and the processing line. The selective routing mechanism serves as an intermediary that directs containers to appropriate paths based on their orientation, simplifying the overall system architecture while maintaining versatility.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Productivity

If multiple handling robots are arranged on both sides of conveyor, then processing capacity is improved, but energy consumption increases

Engineering Contradiction:
Improveprocessing capacityVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent applies universality by designing a single unscrambling device that can handle containers of various orientations and types. The selective routing mechanism and carrier design allow the same device to process different container configurations, eliminating the need for multiple specialized handling robots and reducing overall energy consumption.

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

Solution Approach 2:

The patent changes the parameter of container orientation handling by implementing a system that accepts containers in any initial orientation rather than requiring specific orientations. This parameter change (from fixed orientation requirement to flexible orientation acceptance) reduces the need for multiple energy-consuming handling robots while maintaining high processing capacity.

Inventive Principle:
Principle #35Parameter changes
