Solution Overview

Problem

Existing sliding wall systems with automatic carriages require complex and costly switching mechanisms to adjust the travel path of carriages, making them mechanically intricate and prone to maintenance issues.

Innovation Solution

A sliding wall system with a carriage that features an arrangement element with multiple receiving positions for guide elements, allowing for simple and cost-effective adjustment of the carriage's travel path using passive mechanical elements, eliminating the need for actively switchable components. The carriage includes a suspension element and running wheels that contact the profile element, with a profile gap allowing the suspension element to protrude, enabling the carriage to support the sliding wall element and adjust its path through the selection of guide elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If complex switching mechanisms are used to adjust the travel path of carriages in automatic sliding wall systems, then the adaptability of the system is improved, but the device complexity and maintenance requirements increase significantly

Engineering Contradiction:
Improvetravel path adjustment capabilityVSAvoidswitching mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The profile element is divided into multiple segments or sections, each with specific geometric features that guide the carriage along different paths. The carriage itself is segmented with separate guide elements that can be independently positioned, allowing path selection without complex switching mechanisms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system uses movable or adjustable guide elements on the carriage that can be positioned at different locations along the profile element. This dynamic repositioning allows the same physical structure to define multiple travel paths without requiring active switching mechanisms.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If complex switching mechanisms are installed in the profile element to enable path selection, then the versatility of the sliding wall system is improved, but the manufacturing costs and production complexity increase

Engineering Contradiction:
Improveroute definition capabilityVSAvoidproduction cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The profile element is designed as a modular structure with repeating geometric features at different positions. These segmented features can be manufactured using standard fabrication processes without requiring complex assembly or specialized equipment, thereby reducing production costs while maintaining route definition capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of manufacturing unique complex switching mechanisms for each path configuration, the invention uses repeated geometric features that are copied along the profile element. These replicated features work with corresponding guide elements on the carriage to define multiple paths, significantly simplifying manufacturing.

Inventive Principle:
Principle #26Copying

3Adaptability or versatility

If actively switchable components are used to define carriage routes, then the adaptability of the sliding wall system is improved, but the reliability and maintenance requirements worsen

Engineering Contradiction:
Improvepath selection capabilityVSAvoidmaintenance susceptibility
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

Instead of using active switching mechanisms that move or change configuration to select paths, the invention inverts the approach by using fixed geometric features on the profile element that passively guide the carriage. The adaptability is achieved through the arrangement of these fixed features rather than through active switching components.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The carriage's guide elements automatically engage with the corresponding geometric features on the profile element based on their relative positions, thereby self-selecting the travel path without requiring external switching control. This passive self-guidance mechanism eliminates the need for actively switchable components and improves reliability.

Inventive Principle:
Principle #25Self-service
