Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If boreholes are created using separate punching devices before application, then openings can be made in the profile sealing strand, but numerous handling steps and additional processing time are required

Engineering Contradiction:

Improveborehole creationVSAvoidprocessing time

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The patent combines the drilling function with the profile sealing strand application device by integrating a drilling unit into the application head. This allows boreholes to be created directly in the profile sealing strand during the application process itself, eliminating the need for separate punching operations and reducing handling steps while maintaining manufacturing precision

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The drilling unit is positioned and configured in advance within the application head, with drilling parameters and positioning ready before the application process begins. This preliminary preparation enables immediate borehole creation as the profile sealing strand is applied, avoiding delays that would occur with separate post-application drilling operations

Inventive Principle:

Principle #10Preliminary action

2Manufacturing precision

If the component with the seal is guided to a stationary drilling station for each borehole, then boreholes can be made accordingly, but additional handling steps and processing time are required

Engineering Contradiction:

Improveborehole positioningVSAvoidhandling steps

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

Instead of moving the profile sealing strand to a stationary drilling station, the patent inverts the approach by bringing the drilling unit to the profile sealing strand through the application head. The drilling unit moves with the application process, eliminating the need to guide the component to multiple stationary stations and significantly reducing handling steps while maintaining precise borehole positioning

Inventive Principle:

Principle #13The other way round (Inversion)

3Productivity

If a drilling unit is integrated into the application head, then boreholes can be created directly during application, but the device complexity increases

Engineering Contradiction:

Improveapplication efficiencyVSAvoiddrilling jig structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The application head is designed with multi-functionality, serving both as the application mechanism for the profile sealing strand and as the drilling station. The drilling unit is integrated into the existing application head structure, allowing it to perform dual functions without requiring entirely separate systems, thereby limiting the increase in device complexity while achieving improved application efficiency

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The drilling function is segmented as a separate drilling unit that can be independently controlled and positioned within the application head. This modular segmentation allows the drilling mechanism to be added as a distinct functional module rather than redesigning the entire application device, thus managing device complexity while enabling direct borehole creation during application

Inventive Principle:

Principle #1Segmentation
