Solution Overview

Problem

Existing motor-driven door and window systems require electrical connections to be manually managed, are bulky, and necessitate multiple control devices for each unit, complicating installation and maintenance, especially in double glazing applications where internal failures require full disassembly.

Innovation Solution

An actuating system with a magnetically coupled contact holder plate and a portable control device that eliminates internal electrical components in the door or window frame, using a rechargeable battery-powered control unit that can connect magnetically to the motor apparatus, allowing for simplified electrical connections and centralized control for multiple units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a remote control with transmitting means is used to activate motor control devices, then remote actuation capability is achieved, but the device complexity increases due to additional transmitting and receiving components

Engineering Contradiction:
Improveremote actuation capabilityVSAvoidtransmitting and receiving components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces electromagnetic remote control systems with a mechanical coupling system. A portable control device with electrical contacts makes direct physical contact with the motor apparatus, eliminating the need for separate transmitting and receiving components while achieving the same control function.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The portable control device serves multiple functions: it provides electrical power through its power supply means, transmits control signals through electrical contacts, and physically couples to the motor apparatus. This multi-functional design eliminates the need for separate control and power transmission systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If command and control devices are integrated in each door or window frame, then each motor apparatus has dedicated control, but the quantity of devices must be multiplied for multiple units

Engineering Contradiction:
Improvededicated control for each motorVSAvoidnumber of control devices
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The portable control device is designed to be universally compatible with multiple motor apparatus units. The same single device can control different Venetian blinds or roller shutters by physically coupling to each unit's motor, eliminating the need for separate integrated control devices for each window or door.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The control function is extracted from the door or window frame structure and consolidated into a separate portable control device. This allows the control capability to be removed from each individual unit while maintaining the ability to control multiple units with a single device.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If electrical outlet elements with non-negligible thickness are installed in frames, then electrical connection is enabled, but the aesthetic appearance of the frame is altered

Engineering Contradiction:
Improveelectrical connection capabilityVSAvoidaesthetic appearance of frame
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

Instead of installing fixed electrical outlets in the frame that protrude outward, the patent inverts the approach by bringing the electrical connection interface to the portable control device. The electrical contacts are housed in the handheld controller rather than in the window or door frame, eliminating the need for visible frame modifications.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The portable control device acts as an intermediary that carries the electrical connection interface. Rather than modifying the frame to accommodate outlets, the control device itself provides the electrical contacts needed for powering and controlling the motor apparatus.

Inventive Principle:
Principle #24Intermediary (Mediator)
