Solution Overview

Problem

Furniture panels with integrated electrical charging capabilities restrict the usable surface area due to the presence of sockets and cables, limiting mobility and flexibility in charging electrical devices.

Innovation Solution

A furniture panel with an inductive charging system, where an electronic component with a coil is embedded in the panel's underside, allowing wireless energy transfer to devices placed on the surface, eliminating the need for sockets and cables, and optionally enabling data transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a socket is integrated into the furniture panel for charging electrical devices, then electrical devices can be charged on the furniture panel, but the usable surface area of the furniture panel is reduced

Engineering Contradiction:
Improvecharging capabilityVSAvoidusable surface area
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent extracts the charging function from the surface of the furniture panel by integrating a socket into a recess on the underside of the panel. This allows the top surface to remain completely clear and usable, while the charging functionality is provided through the recessed socket on the bottom side, eliminating the trade-off between charging capability and usable surface area.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If a charging cable is used to connect the electrical device to the socket, then the electrical device can be charged, but the cable lies on the worktop and restricts the available area and creates safety hazards

Engineering Contradiction:
Improvecharging capabilityVSAvoidcable obstruction and safety risk
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent removes the charging cable from the work surface by integrating the socket into the furniture panel itself. The electrical device can be charged by placing it directly on the panel surface near the recess, eliminating the need for external cables to lie across the worktop, thus removing the obstruction and safety hazards while maintaining charging capability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If a socket is provided on the furniture panel, then charging is enabled, but corresponding chargers and cables must be carried along which limits mobility and flexibility

Engineering Contradiction:
Improvecharging capabilityVSAvoidmobility and flexibility
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent merges the charging functionality directly into the furniture panel by providing a recess with an integrated socket on the underside. This combination allows the furniture panel itself to serve as the charging station, eliminating the need to carry separate chargers and cables, thereby enhancing mobility and flexibility while maintaining charging capability.

Inventive Principle:
Principle #5Merging (Combining)
