Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing arrangements for electromotive furniture drives lack efficient and convenient methods for establishing communication connections with data devices, particularly in environments where multiple pieces of furniture are in close proximity, leading to cumbersome cable connections and potential moisture or dust exposure issues.

Innovation Solution

The implementation of a communication connection with two transmission paths, one for identification and one for data transmission, allowing for wireless communication between the electromotive furniture drive and the data device, enabling unambiguous assignment and eliminating the need for new cable connections, while using visible or invisible identification codes for recognition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a cable connection is used to connect the data device to the electromotive furniture drive, then reliable data transmission is achieved, but the setup becomes cumbersome and requires detaching cable pullout safeguards and removing plugs

Engineering Contradiction:

Improvedata transmission reliabilityVSAvoidconnection setup ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical cable connection system with a wireless communication system. The data device communicates with the electromotive furniture drive via wireless signals, eliminating the need for physical plug connections, cable pullout safeguards, and manual plugging/unplugging operations while maintaining reliable data transmission for maintenance and programming tasks

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If a separate plug connection for data devices is provided, then data transmission capability is enabled, but the plug connection must be protected against moisture and dust penetration requiring covers and seals

Engineering Contradiction:

Improvedata device connectivityVSAvoidmoisture and dust exposure

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent eliminates the need for physical plug connections by implementing wireless communication between the data device and the electromotive furniture drive. This substitution removes the vulnerability to moisture and dust penetration entirely, as no openings or seals are required in the furniture drive housing for data communication purposes

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If multiple pieces of furniture are set up in direct proximity, then space utilization is improved, but identification of the specific furniture unit becomes difficult

Engineering Contradiction:

Improvespace utilizationVSAvoidfurniture unit identification

Core Design Contradiction:

ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent introduces an identification code as an intermediary element that enables unique identification of each electromotive furniture drive. The data device reads and processes this identification code to establish communication with the specific furniture unit, allowing accurate targeting even when multiple furniture pieces are positioned close together

Inventive Principle:

Principle #24Intermediary (Mediator)

4Object-affected harmful factors

If covers and seals are installed to protect plug connections, then protection against moisture and dust is achieved, but the operation becomes more complex requiring attachment and detachment of covers

Engineering Contradiction:

Improveprotection against moisture and dustVSAvoidoperation procedure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical protection system (covers and seals) with a wireless communication system. This eliminates the need to attach or detach protective covers for data device connections, simplifying the operation procedure while maintaining protection against moisture and dust by keeping the housing intact

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
