Solution Overview

Problem

Existing methods for producing T-profile rails for grid ceilings are costly due to high material consumption and lack efficiency in the online production process, often resulting in uneven opening sizes during the widening process.

Innovation Solution

A T-profile rail design featuring a profile depression with lateral guide surfaces ensures uniform widening of openings, achieved through a folding process that connects partial longitudinal regions, and the formation of double-walled areas with beads for enhanced stability and material embossing to prevent waviness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If openings are widened in longitudinal areas to reduce material consumption, then material costs are reduced, but opening uniformity deteriorates due to lack of transverse fixation

Engineering Contradiction:
Improvematerial consumptionVSAvoidopening uniformity
Core Design Contradiction:
Loss of substanceVSManufacturing precision

Solution Approach 1:

A guide section with lateral guide surfaces is introduced as an intermediary element during the widening process. This guide section temporarily constrains the longitudinal areas in the transverse direction, ensuring uniform opening enlargement while allowing the widening process to proceed. After widening, the guide section is removed, leaving uniformly enlarged openings without compromising material consumption benefits.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The guide section is positioned and fixed in advance before the widening process begins. This preliminary positioning ensures that the longitudinal areas are properly constrained in the transverse direction before material removal or expansion occurs, preventing non-uniform opening shapes during the subsequent widening operation.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If high processing speeds of up to 150 m/min are achieved to increase throughput, then productivity is improved, but manufacturing precision deteriorates due to reduced control over the widening process

Engineering Contradiction:
ImprovethroughputVSAvoidopening uniformity
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The guide section serves as a mechanical intermediary that maintains opening uniformity even at high processing speeds. By providing physical constraints through lateral guide surfaces, it ensures that the widening process remains controlled and uniform regardless of the line speed, allowing throughput to reach 150 m/min without sacrificing precision.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If the profile is produced in an online process with continuous forming steps, then productivity is improved, but manufacturing complexity increases due to the need for precise coordination of multiple operations

Engineering Contradiction:
ImprovethroughputVSAvoidproduction process complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The guide section is designed with multi-functionality: it provides transverse fixation during widening, guides the material through the forming process, and can be integrated into existing online production equipment. This universal design reduces the need for separate specialized devices for each function, thereby reducing overall system complexity while maintaining high productivity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The invention relates to a construction profile, in particular a T, C, U, V, H, L, M, W, Q or hat profile, having an in particular metallic, elongated base body (14). The base body comprises a center region (15) extending in the longitudinal direction and designed substantially closed and at least two longitudinal regions (16) extending on both sides of the center region (15). Openings (13) expanded crosswise to the longitudinal extension of the base body (14) are arranged in the longitudinal regions (16). A profile recess (18) or rise having lateral guide surfaces (19) and extending in the longitudinal direction of the base body (14) over the entire length thereof is formed in the center region (15) of the base body (14). The invention further relates to a method and to a device for producing such a construction profile.
