Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for mounting filling and limit level sensors on containers require mechanical changes, which can damage returnable containers and are inefficient, especially when the containers are not owned by the operator.

Innovation Solution

A dual adhesive system is used to attach the sensor, where a pressure-sensitive adhesive provides initial positioning and a second adhesive with a solidification mechanism ensures a stable, load-bearing attachment, allowing for secure mounting without mechanical modifications to the container.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mechanical changes are made to the container to mount threaded connectors or flange adapters, then the sensor can be permanently and securely attached, but the container wall is damaged and the mounting process becomes complex

Engineering Contradiction:

Improveattachment reliabilityVSAvoidcontainer wall damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces mechanical attachment systems (threaded connectors, flange adapters requiring drilling and fastening) with a chemical bonding system using two-component adhesives. The adhesive system provides permanent, load-bearing attachment without mechanical penetration or damage to the container wall, thereby substituting mechanical fastening with chemical bonding.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent utilizes parameter changes in the adhesive system, specifically the transition from liquid adhesive components to a solidified bonded state. The two-component adhesive undergoes chemical reaction and solidification, changing its physical parameters from fluid to rigid, thereby providing progressive attachment strength without mechanical damage to the container.

Inventive Principle:

Principle #35Parameter changes

2Ease of manufacture

If a single adhesive system is used to attach the sensor, then the attachment process is simple, but the attachment may not provide sufficient load-bearing capacity or adaptability to different container surfaces

Engineering Contradiction:

Improveattachment process simplicityVSAvoidattachment load-bearing capacity

Core Design Contradiction:

Ease of manufactureVSStrength

Solution Approach 1:

The patent employs a composite adhesive system consisting of two different adhesive components that are mixed and applied together. This composite approach combines the properties of both adhesives to achieve superior load-bearing capacity, chemical resistance, and adaptability to different container surfaces, while still maintaining a relatively simple two-step application process.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent segments the attachment function into two distinct adhesive components that are applied in sequence or combination. This segmentation allows each adhesive component to contribute specific properties (such as initial bonding strength and final cured strength) while together providing comprehensive attachment performance that neither adhesive could achieve alone.

Inventive Principle:

Principle #1Segmentation

3Loss of time

If pressure-sensitive adhesive is used for quick attachment, then the initial positioning is fast, but the attachment lacks long-term stability and load-bearing capacity

Engineering Contradiction:

Improveattachment timeVSAvoidattachment durability

Core Design Contradiction:

Loss of timeVSDuration of action of stationary object

Solution Approach 1:

The patent applies preliminary action through the first adhesive component that provides immediate initial bonding and positioning of the sensor to the container wall. This preliminary attachment stabilizes the sensor in the correct position while the second adhesive component cures, ensuring both quick initial fixation and long-term durability through the combined action of both adhesives.

Inventive Principle:

Principle #10Preliminary action
