Wireless Drawer Power Coupling for Cable-Free Furniture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional furniture lacks a simple and efficient way to transmit electrical energy and control signals between its body and movable parts, often requiring cumbersome cables and multiple operating devices, which complicates the structure and operation.
Innovation Solution
A coupling device with inductive or capacitive coupling elements, such as coils, is used for wireless transmission of electrical energy and data between the furniture body and movable parts, allowing for centralized control of electrical devices using a single operating device on one drawer, eliminating the need for cables and reducing the number of operating devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are used to transmit electrical energy and control signals between furniture body and movable parts, then reliable energy transmission is achieved, but the structure becomes complex and operation becomes cumbersome
Solution Approach 1:
The patent replaces the mechanical cable-based electrical connection system with an inductive coupling system using electromagnetic fields. The coupling device includes a first coil on the furniture body and a second coil on the movable furniture part, which wirelessly transmit electrical energy and control signals through electromagnetic induction, eliminating the need for physical cable connections and reducing structural complexity.
Solution Approach 2:
The patent introduces an intermediate electromagnetic field as a mediator between the furniture body and movable parts for energy and signal transmission. The coupling device uses electromagnetic fields generated by the coils to transfer power and control signals without direct physical contact, serving as an intermediary that replaces cable-based mechanical connections.
2Ease of operation
If multiple operating devices are provided on each drawer, then each drawer can be independently controlled, but the number of operating devices increases and appearance is degraded
Solution Approach 1:
The patent implements a universal control system where a single operating device on one drawer can control multiple drawers through wireless communication. The coupling device enables the operating device to send control signals to electrical devices on different drawers without requiring separate operating devices on each drawer, achieving multi-functionality and reducing the total number of control elements.
Solution Approach 2:
The patent merges the control functions of multiple drawers into a single operating device. Instead of having separate control elements on each drawer, the system combines all control functionality into one location, allowing a user to control multiple drawers from a single interface, thereby reducing the number of operating devices and improving appearance.
3Reliability
If precise alignment of coupling devices is required for reliable energy transmission, then transmission reliability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent makes the coupling device dynamic by allowing the housing containing the second coil to move relative to the furniture body. The housing is designed to accommodate positional variations and maintain reliable electromagnetic coupling even when the drawer is in different positions, eliminating the need for precise fixed alignment and reducing manufacturing precision requirements.
Solution Approach 2:
The patent changes the operational parameters of the coupling device by designing the housing to move to a limited extent, allowing the system to adapt to positional variations. This movement capability enables the coupling device to maintain optimal electromagnetic coupling conditions across different drawer positions without requiring high manufacturing precision for fixed alignment.
