Solution Overview

Problem

Existing furniture drives are difficult to position accurately and efficiently on or in a furniture body, requiring significant effort and resulting in imprecise assembly, which affects the proper movement of movable furniture parts.

Innovation Solution

Incorporating a movable assembly stop that can be placed on the furniture body, allowing the drive unit to be positioned at a predetermined location, with the option to pivot or slide between positions, and being easily replaceable if damaged, facilitating standardized and simplified installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a furniture drive is positioned on or in a furniture body using a ruler and pencil, then the installation can be performed, but the positioning precision is poor and requires great effort

Engineering Contradiction:
Improvepositioning precisionVSAvoidinstallation effort
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The assembly stop is pre-configured on the drive unit at a predetermined position that corresponds to the correct installation location on the furniture body. This preliminary positioning feature eliminates the need for manual measurement and marking during installation, allowing the drive unit to be directly positioned at the correct location by simply placing the assembly stop against the furniture body surface.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The assembly stop acts as an intermediary element between the drive unit and the furniture body. It serves as a positioning mediator that transfers the predetermined correct position from the drive unit design to the actual installation location on the furniture body, ensuring accurate positioning without requiring the installer to directly measure and mark the exact position.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the assembly stop is made movable between positions, then the installation flexibility is improved, but the device complexity increases

Engineering Contradiction:
Improveinstallation flexibilityVSAvoidassembly stop mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The assembly stop is designed with movable mounting that allows it to pivot or slide between a first position (where it is received in a recess of the drive unit) and a second position (where it protrudes to contact the furniture body). This dynamic capability provides installation flexibility while maintaining relatively simple construction through pivot pins or sliding mechanisms.

Inventive Principle:
Principle #15Dynamics
