Solution Overview

Problem

Existing devices for determining the filling volume of containers filled with liquids or granules are not accurate and efficient, often leading to overflow issues, especially when different container sizes are used, and require costly coding or recognition units.

Innovation Solution

A device utilizing a reflection light barrier with a beam source and sensor that can rotate to determine the fill level and geometry of containers, allowing for precise dosing and preventing overflow, regardless of container size, without the need for special coding or recognition units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual interruption options are provided to prevent overflow, then user control is improved, but device complexity increases and operation becomes less automated

Engineering Contradiction:
Improveoverflow preventionVSAvoidcontrol system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system uses automatic recognition of container geometry and material properties to self-regulate the filling process, eliminating the need for manual intervention. The control unit automatically adjusts filling parameters based on sensor data about container size and material characteristics.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors filling progress using sensors that detect material level and container fill state, providing real-time feedback to the control unit which adjusts the filling process accordingly to prevent overflow without requiring user intervention.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If special containers with coding or recognition units are used, then container identification accuracy is improved, but manufacturing cost increases

Engineering Contradiction:
Improvecontainer identification accuracyVSAvoidcontainer manufacturing cost
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The system replaces complex mechanical or electronic recognition units in containers with optical sensors that read geometric and optical properties of standard containers. The sensor system detects container shape, size, and material properties using light reflection and transmission characteristics.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

Instead of requiring unique coding in each container, the system creates an optical 'copy' or model of the container's geometric and optical properties through sensor measurement, using this model to determine appropriate filling parameters.

Inventive Principle:
Principle #26Copying

3Productivity

If fixed filling volumes are used, then dispensing speed is improved, but adaptability to different container sizes decreases

Engineering Contradiction:
Improvedispensing speedVSAvoidcontainer size adaptability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts filling volume and rate based on real-time detection of container geometry and material properties. The control unit modifies filling parameters during the dispensing process to optimize both speed and adaptability to different container types.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes key filling parameters such as volume, rate, and pressure based on detected container characteristics and material properties, allowing rapid adaptation to different container sizes while maintaining high dispensing efficiency.

Inventive Principle:
Principle #35Parameter changes
