Solution Overview

Problem

Existing guide devices for displaceable and rotatable separating elements in functional units, such as cupboards and kitchens, require significant space and complex designs, limiting their universality and causing mechanical noise and load issues, while also being aesthetically unappealing when visible.

Innovation Solution

A guide device with a guide carriage that can be displaced along a running rail and connected rotatably to a separating element, featuring a carriage body with idler wheels and a hinge lever that allows the separating element to be stably moved and rotated, taking up minimal space and being hidden from view, enabling easy operation with minimal effort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If guide rails and drive mechanisms are mounted on both underside and top of cabinet, then separating elements can be guided and driven, but device complexity and space requirements increase significantly

Engineering Contradiction:
Improveguiding and driving capabilityVSAvoidmechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention extracts the guiding and driving functions from the traditional dual-side configuration and consolidates them into a single guide device mounted only on the front of the cabinet. The guide carriage integrates both guiding rollers and drive mechanisms within a single structure that attaches to the front surface, eliminating the need for separate mounting on underside and top.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The guide carriage merges the guiding function (via rollers) and driving function (via drive mechanisms) into a single integrated component. This combined structure is mounted on the front of the cabinet, consolidating multiple functions into one location and reducing overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If traditional guide devices are used, then separating elements can be moved, but mechanical noise and load issues occur

Engineering Contradiction:
Improvemovement capabilityVSAvoidmechanical noise
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The guide carriage acts as an intermediary component between the separating element and the cabinet front. It provides a buffered connection that reduces direct mechanical contact and impact forces, thereby minimizing noise generation while maintaining smooth movement capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If guide device elements are visible after wall elements are opened, then mechanism can be seen, but aesthetic appearance deteriorates

Engineering Contradiction:
Improvemechanism visibilityVSAvoidaesthetic appearance
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The guide device is strategically positioned and designed so that its functional elements (rollers, drive mechanisms) are located in areas that remain hidden when the cabinet is in closed position. The mounting on the front surface allows the mechanism to be concealed behind the cabinet facade while maintaining full functionality.

Inventive Principle:
Principle #3Local quality

AI summary

The device (1) has a guide carriage (2) slidable along a running rail (4) and pivotally connectable to a separation element (5A). The guide carriage comprises a carriage body with a carriage head and a carriage foot. The carriage head and the carriage foot are connected with one another by a connecting beam. The carriage head holds a support wheel (26) and guide wheels. The carriage foot is torque-proof connected with an end piece of a hinge lever (32). Another end piece is pivotally held by a hinge shaft that is connectable to a sidewall of the separation element. An independent claim is also included for a functional entity.
