Solution Overview

Problem

Existing devices struggle to achieve a reliable and efficient flush alignment of profile stacks, particularly for transport purposes, as they often require additional measures beyond aligning the stack width to ensure alignment with respect to the stack length.

Innovation Solution

A device with a common frame pivotable about a rotation axis, incorporating a stack support, depth stop, and hold-down device, which subjects the profile stack to oscillating movements in an alignment position, utilizing gravity and vibration to separate adhered profiles and align them flush.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If additional measures are taken to align the stack length after width alignment, then alignment precision is improved, but device complexity increases

Engineering Contradiction:
Improvealignment precisionVSAvoiddevice complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent combines width alignment and length alignment functions into a single alignment unit. The side stops handle width alignment while the depth stop and pivotable frame handle length alignment simultaneously, eliminating the need for separate alignment devices and operations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The alignment unit is designed to be pivotable about a rotation axis, allowing it to transition between a receiving position (parallel to insertion plane) and an alignment position (at pivot angle). This dynamic mechanism enables the frame to tilt and align stack lengths efficiently using gravity and vibration.

Inventive Principle:

2Manufacturing precision

If static friction is overcome to separate adhered profiles, then alignment precision is improved, but force requirements increase

Engineering Contradiction:

Solution Approach 1:

The patent introduces a vibration drive that generates oscillating movements in the alignment unit. This vibration reduces static friction between adhered profiles, allowing them to separate and slide into proper alignment positions without requiring excessive force.

Inventive Principle:
Principle #18Mechanical vibration

Solution Approach 2:

The vibration drive applies periodic oscillating movements to the alignment unit, creating repeated small displacements that gradually overcome static friction and enable profiles to slide into alignment positions over time.

Inventive Principle:

Solution Approach 1:

The alignment unit is designed as a pivotable frame that can rotate about a rotation axis between receiving and alignment positions. This dynamic design allows the unit to automatically tilt and align stacks using gravity and vibration, simplifying operation despite the added mechanical complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The pivotable frame changes its orientation parameter by rotating from a horizontal receiving position to a tilted alignment position at a specific pivot angle. This parameter change enables the alignment function while maintaining a relatively simple mechanical structure.
