Solution Overview

Problem

Existing roller carriages for sliding doors require specific mounting devices for each function, leading to increased complexity and mounting time due to the need for different orientations and manipulation interfaces, making the installation process costly and time-consuming.

Innovation Solution

A roller carriage design with at least two mounting devices on one side, featuring a roller module for displacement along a roller running path and a basic body for attachment, where all manipulation interfaces are accessible from the same side, allowing for quicker and simpler mounting by using a uniform tool for different functions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple mounting devices are provided for different mounting functions, then the functionality and versatility of the roller carriage is improved, but the complexity of the roller carriage and the time required for mounting increases

Engineering Contradiction:
Improvemounting functionVSAvoidroller carriage
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The roller carriage is designed with multiple mounting devices (height adjusting device, attachment device, accessory device) that can perform different mounting functions. Each mounting device includes a manipulation interface that allows for versatile functionality while maintaining a unified structure, enabling the roller carriage to serve multiple purposes without proportionally increasing overall complexity

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

2Ease of manufacture

If each mounting device has a specific orientation and manipulation interface, then the mounting function can be fulfilled specifically, but the mounting time and expense increase due to the need to locate and adapt to different interfaces

Engineering Contradiction:
Improvemounting functionVSAvoidmounting time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

All mounting devices on the roller carriage are designed with manipulation interfaces that are homogeneous in their accessibility - they are all disposed on the first side of the roller carriage. This allows the installation technician to access all mounting functions from a single side without needing to locate scattered interfaces or change tools frequently, significantly reducing mounting time and expense

Inventive Principle:
Principle #33Homogeneity

3Adaptability or versatility

If manipulation interfaces are disposed on different sides of the roller carriage, then each mounting device can operate independently, but the ease of operation deteriorates due to the need to access different sides for different functions

Engineering Contradiction:
Improvemounting device independenceVSAvoidmounting operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

Instead of distributing manipulation interfaces across different spatial locations (different sides of the roller carriage), all interfaces are consolidated on the first side. This dimensional reorganization maintains the independence and functionality of each mounting device while dramatically improving ease of operation, as all interfaces are accessible from a single side without requiring the technician to move around the device

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A roller carriage for the reception of a sliding door includes a roller module for the displaceable affixing at a roller running path and a basic body for the attachment to the sliding door, wherein at least two mounting devices are provided for realizing respectively one mounting function of the roller carriage. Each mounting device includes at least one mounting element with a manipulation interface for applying a mounting force for performing a mounting movement of the mounting element. The manipulation interfaces of the mounting elements of the at least two mounting devices are disposed on a first side of the roller carriage, and a bearing device of the roller module for the displaceable affixing at the roller running path is disposed on the opposing second side of the roller carriage.
