A system comprising a corner profile element with flange sections arranged at a predefined angle, featuring first and second openings for mounting aids and adhesives, simplifies the bonding process by allowing the passage of mounting aids and adhesives, enhancing stability and reliability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a corner profile element is fixed to a corner stud using screws, then the structure can be assembled, but the structure is difficult to handle and lacks stability

Engineering Contradiction:
Improvestructural stabilityVSAvoidhandling difficulty
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces adhesive as an intermediary substance between the corner profile element and corner stud, replacing direct mechanical fastening with screws. The adhesive layer mediates the connection, providing both structural stability through chemical bonding and ease of operation by eliminating complex screw assembly procedures. The flange sections with openings facilitate adhesive application and distribution, ensuring reliable bonding while simplifying the mounting process.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If mounting aids and adhesives are applied through a complex structure, then structural integrity can be maintained, but material costs and production complexity increase

Engineering Contradiction:
Improvestructural integrityVSAvoidproduction complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The corner profile element is segmented into flange sections with integrated openings, separating the bonding function from the structural profile. This segmentation allows adhesive and mounting aids to be applied through the openings directly to the bonding surfaces, ensuring structural integrity while simplifying production. The openings are strategically positioned to facilitate material application without requiring complex post-processing or additional assembly steps.

Inventive Principle:
Principle #1Segmentation

3Reliability

If adhesive is applied to bond flange sections to wall elements, then a stable structure is achieved, but the bonding process is complex and time-consuming

Engineering Contradiction:
Improvebonding stabilityVSAvoidbonding process time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The flange sections are pre-formed with integrated openings during manufacturing, preparing the structure for rapid adhesive application. The openings are positioned and sized to optimize adhesive flow and distribution, allowing workers to apply bonding material quickly and evenly across the bonding surfaces. This preliminary preparation eliminates the need for time-consuming on-site fabrication or complex bonding procedures, achieving stable bonds efficiently.

Inventive Principle:
