Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing power requirements of electronic devices on common surfaces are hindered by the presence of cords, reducing available surface space for other activities, and existing solutions do not effectively integrate wireless charging capabilities with power backup and modular configurations.
Innovation Solution
A multi-layered surface integrating a top layer for visibility, a second layer with a grid of light sources and power nodes for wireless charging, and a third layer with a power supply and uninterrupted power source, allowing for modular wireless charging pads and automatic configuration via Bluetooth or NFC, with optional backup power from a rechargeable battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If cords are laid across the surface to power electronic devices, then power supply is achieved, but the amount of surface space available for other activities decreases
Solution Approach 1:
The patent extracts the power transmission function from physical cords and relocates it to an embedded wireless power grid within the surface. The power grid includes multiple power nodes distributed throughout the surface layers, eliminating the need for external cords while maintaining power supply capability.
Solution Approach 2:
The patent replaces the mechanical cord-based power transmission system with a wireless electromagnetic power transmission system. The embedded power grid uses wireless power transfer technology to deliver power to devices without physical contact, thereby freeing up surface space.
2Area of stationary object
If wireless charging pads are added to provide wireless charging, then surface space is freed up, but device complexity increases
Solution Approach 1:
The patent merges the wireless charging pad functionality directly into the surface structure itself. The charging pads are integrated into the existing power grid and control system, sharing common components such as the power supply, control electronics, and communication interfaces, thereby reducing overall system complexity.
Solution Approach 2:
The embedded power grid serves multiple functions: it provides power to devices, supports wireless charging pads, and can potentially support other wireless-powered devices. This multi-functionality reduces the need for separate dedicated systems for each function.
3Adaptability or versatility
If multiple layers with power grid and light sources are integrated, then functionality is enhanced, but manufacturing complexity increases
Solution Approach 1:
The patent divides the surface into multiple functional layers: a first layer containing the power grid, a second layer containing light sources, and a third layer providing structural support. Each layer can be manufactured separately and then assembled, reducing the complexity of manufacturing the complete multi-functional surface.
Solution Approach 2:
The patent nests functional components within the layered structure, with the power grid embedded in the first layer and light sources in the second layer. This nested arrangement allows for compact integration of multiple functions while maintaining a relatively simple overall structure that can be manufactured using standard layering techniques.
