Solution Overview

Problem

Existing arrangements for guiding sliding or folding-sliding doors are difficult to assemble and transport due to support elements that move freely and require manual holding during assembly, necessitating securement against displacement.

Innovation Solution

The introduction of securing devices with mounting bodies and securing elements that lock and unlock relative positions, allowing stable assembly and transport, and include force accumulators to prevent accidental unlocking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the support element is mounted on the furniture wall via a guide system and can move freely, then the sliding door can be easily assembled and moved, but the support element requires manual holding during assembly and must be secured against displacement during transport

Engineering Contradiction:
Improveease of assemblyVSAvoidstability during transport
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The securing device transitions from a static fixed state to a dynamic movable state. During transport, the securing element holds the mounting bodies in a fixed securing position. During assembly, the securing element can be moved to a release position, allowing the support element to move freely on the guide system. This dynamic state change resolves the contradiction between stability during transport and ease of assembly.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The securing device is pre-configured with securing elements that automatically engage to hold the mounting bodies in position during transport. This preliminary securing action eliminates the need for manual holding during assembly while maintaining stability during transport, as the securing mechanism is already in place and can be easily activated or deactivated as needed.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If traditional securing devices like screws or cotter pins are used, then the support element can be secured during transport, but the securing devices must be disposed of, collected, and stored separately

Engineering Contradiction:
Improvestability during transportVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The securing element is integrated into the mounting bodies as an inherent component rather than being a separate external fastener. The securing element can be formed as one piece with one or both mounting bodies, eliminating the need for separate screws or cotter pins. This merging of components simplifies assembly and eliminates the need for separate disposal, collection, and storage of securing devices.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The securing device is designed to be self-contained and self-sufficient. The securing element automatically engages with the mounting bodies to provide stabilization during transport without requiring additional tools or separate components. The entire securing mechanism remains in the assembly and serves its function without needing external intervention for disposal or storage.

Inventive Principle:
Principle #25Self-service

3Ease of manufacture

If the securing devices remain in the assembly throughout the process, then no additional disposal or storage is needed, but the securing devices must be designed to allow easy transition between secured and movable states

Engineering Contradiction:
Improveassembly simplicityVSAvoidsecuring mechanism complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The securing device is divided into distinct functional components: mounting bodies and securing elements. The securing element can be a separate component that engages with the mounting bodies, or it can be integrated into one of the mounting bodies. This segmentation allows for simple design and easy transition between secured and movable states without excessive complexity.

Inventive Principle:
Principle #1Segmentation
