Solution Overview

Problem

Conventional electric window coverings face challenges with inconvenient and unsafe battery replacement, as well as aesthetic issues due to exposed charging cables and permanently suspended rods, which limit installation options and user experience.

Innovation Solution

A charging system with an extensible device that allows for easy charging of electric window coverings at various heights, featuring a power storage device connected to an extension object with a stiffness, enabling electric power transmission to the power supply without the need for external tools or exposed cables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If a power transmission wire is used to connect the power supply device to the electric window covering, then electricity can be transmitted to power the motorized tube, but the wire appears abrupt and spoils the overall appearance of the room

Engineering Contradiction:
Improveelectric power transmissionVSAvoidaesthetic appearance
Core Design Contradiction:
PowerVSShape

Solution Approach 1:

The patent extracts the power transmission function from a visible wire and relocates it to an extensible charging device that can be temporarily extended only when needed for charging. The charging device stores power locally and transmits it wirelessly or through a hidden connection mechanism, eliminating the need for a permanently visible power wire across the room.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The charging device incorporates an extensible mechanism that allows the charging component to dynamically extend to the window covering location only when charging is needed, then retract to maintain aesthetic appearance. This dynamic extension and retraction resolves the contradiction between power transmission capability and visual aesthetics.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the power supply device is located far from the electric window covering installation location, then installation flexibility is improved, but a power transmission wire is required which limits installation options due to safety regulations

Engineering Contradiction:
Improveinstallation location flexibilityVSAvoidpower transmission infrastructure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The extensible charging device serves as an intermediary between the power supply and the window covering. It can be positioned at convenient locations away from the window covering, then extended to establish a temporary connection during charging, avoiding the need for permanent wiring infrastructure that would be constrained by safety regulations.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The charging device pre-stores electrical energy in its power supply unit, performing the power transmission preparation in advance. This eliminates the need for real-time wired power transmission during operation, allowing flexible installation locations without requiring complex power transmission infrastructure to the window covering location.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If batteries are used as power supply devices with limited capacity, then the device can be placed anywhere, but once the batteries run out of power, they have to be replaced which is troublesome

Engineering Contradiction:
Improveinstallation location freedomVSAvoidbattery replacement convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The charging device incorporates an automatic charging mechanism that detects when the window covering's battery needs recharging and autonomously extends to establish a charging connection. This self-service approach eliminates the need for users to manually replace batteries, while the device remains placeable anywhere due to its wireless or extensible charging capability.

Inventive Principle:
Principle #25Self-service

4Reliability

If the charging device is permanently suspended to provide power, then power transmission is reliable, but it occupies space and may be bumped into causing damage

Engineering Contradiction:
Improvepower transmission reliabilityVSAvoidphysical damage risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The charging device employs a dynamic extensible mechanism that keeps the charging component retracted or hidden during normal operation, exposing it only temporarily when charging is required. This dynamic behavior maintains power transmission reliability when needed while minimizing the risk of physical damage by reducing the exposed surface area that could be bumped or damaged.

Inventive Principle:
Principle #15Dynamics

AI summary

An electric window covering is disclosed, which has a motorized assembly for controlling a movement of a covering material, a rechargeable battery for providing electric power to the motorized assembly, an electric power input at an overhead frame coupled with the rechargeable battery, and a separable charging device. The separable charging device has an electrical connector, a conductor and an electric power output provided at an extension object for charging the rechargeable battery through the electric power input. The separable charging device further has a first fixing structure at the extension object adapted to engage with a second fixing structure at the overhead frame for charging the rechargeable battery. After the extension object and the overhead frame are disengaged, the rechargeable battery still provides electric power to the motorized assembly for controlling the movement of the covering material.
