Solution Overview

Problem

Existing section elements require additional on-site processing steps for applying self-adhesive sealing elements, increasing work effort and costs due to high manufacturing speeds.

Innovation Solution

Integrating a plastic sealing element with protrusions that project through openings in the section body, allowing for precise and efficient application during manufacturing, either by spraying, rolling, or extruding, which forms a strong fastening connection with the section body.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If self-adhesive sealing elements are applied on-site by the fitter, then sealing function is achieved, but work effort and processing time are increased

Engineering Contradiction:

Improvesealing functionVSAvoidwork effort

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The sealing element is applied to the section body during the manufacturing process before the section is delivered to the construction site. This preliminary action eliminates the need for on-site application by the fitter, reducing work effort while maintaining the sealing function.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The section element is delivered pre-equipped with the sealing element, allowing it to be self-sufficient and eliminating the need for additional processing steps at the construction site. The sealing element is integrated into the section body during manufacturing.

Inventive Principle:

Principle #25Self-service

2Productivity

If section elements are manufactured at high speeds (up to 150 m/min), then productivity is improved, but precise application of sealing elements becomes difficult

Engineering Contradiction:

Improvemanufacturing speedVSAvoidapplication precision

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The sealing element is applied in a liquid or viscous state through spraying, rolling, or extrusion methods that are compatible with high-speed manufacturing processes. The liquid material can be precisely applied even at high speeds, and subsequently hardens or is foamed to form the final sealing element.

Inventive Principle:

Principle #29Pneumatics and hydraulics

Solution Approach 2:

The sealing element is applied in a different aggregation state (liquid or viscous) during manufacturing, which allows for precise application at high speeds. After application, the material undergoes a phase change to harden or foam, forming the finished sealing element.

Inventive Principle:

Principle #35Parameter changes

3Manufacturing precision

If protrusions are formed by passing liquid plastic material through openings, then fastening precision is improved, but additional processing steps are required

Engineering Contradiction:

Improvefastening precisionVSAvoidprocess complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The formation of protrusions and the application of the sealing element are combined into a single integrated process. The liquid plastic material is extruded or sprayed through openings in the section body, forming protrusions that provide mechanical fastening while the material simultaneously seals the openings.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The sealing element is applied in a liquid or viscous state that allows it to pass through openings and form protrusions. The material then undergoes a phase transition to harden or foam, creating the final fastened and sealed structure in one continuous process.

Inventive Principle:

Principle #36Phase transitions
