Solution Overview
Problem
Existing electrical power systems in work areas lack a compact, self-contained solution for providing both wireless charging and direct-contact power outlets, particularly for portable electronic devices, without requiring specialized tools or training.
Innovation Solution
A compact electrical power unit with a wireless power transmitter and direct-contact outlets, featuring a cylindrical lower housing that secures to a work surface, includes a sensing mechanism to energize only when a compatible receiver is detected, and provides both high voltage AC and low voltage DC power options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless charging and direct-contact outlets are integrated into a single work surface unit, then convenience and functionality are improved, but device complexity increases
Solution Approach 1:
The patent combines wireless charging transmitter, AC power outlet, DC power outlet, and USB data/power receptacles into a single integrated electrical power unit that mounts to the work surface. This merging of multiple power delivery functions into one device provides versatility while managing complexity through unified design.
Solution Approach 2:
The electrical power unit serves multiple functions simultaneously: wireless charging for compatible devices, AC power distribution, DC power distribution, and USB data/power transfer. This multi-functionality allows a single device to replace multiple separate power solutions, improving adaptability across different device types.
2Ease of operation
If the power unit is designed to be self-contained and tool-free for installation, then ease of operation is improved, but manufacturing complexity increases
Solution Approach 1:
The patent replaces traditional mechanical fastening systems (screws, tools, drilling) with a clamp-based mounting system that uses spring tension and friction to secure the unit to the work surface. This substitution allows tool-free installation while maintaining secure attachment, improving ease of operation without requiring specialized manufacturing processes.
3Reliability
If the base extends downwardly to secure to the work surface, then mounting stability is improved, but the profile height increases
Solution Approach 1:
The patent positions the clamping mechanism in the horizontal plane rather than requiring vertical extension. The clamp engages the work surface edge horizontally, providing secure mounting without adding significant vertical profile height. This dimensional approach maintains stability while preserving a low-profile appearance.

AI summary
An electrical power unit is positionable at a work surface and includes an upper housing including an upper surface and a lower surface spaced below the upper surface to define an upper housing chamber. A wireless power transmitter is disposed in the upper housing chamber and is operable to convey electrical energy to a wireless power receiver positioned at or above the upper surface. A base is coupled to the upper housing and extends downwardly therefrom, the base being configured for insertion into an opening formed in the work surface or into a space defined between two adjacent work surfaces. The base is further configured to facilitate securing the electrical power unit to the work surface or the adjacent work surfaces.
