Solution Overview

Problem

Existing automatic door systems lack touch-free operation, require professional installation, and do not provide efficient access control, especially in high-traffic areas, and fail to integrate seamlessly with modern security features like facial recognition and behavior analysis.

Innovation Solution

A compact, self-installable door driving device equipped with wireless power, sensors, an image-capturing module, and communication technologies that enables touch-free operation of various door types, including swinging, sliding, and rotating doors, using wireless communication protocols like Bluetooth or Wi-Fi for remote control and integration with facial recognition and authentication systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automatic door systems are installed in high-traffic areas, then access control efficiency is improved, but the risk of contamination and infection increases

Engineering Contradiction:

Improveaccess control efficiencyVSAvoidcontamination risk

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces manual mechanical door operation with an automated electromechanical system that uses sensors to detect approaching users and triggers motorized door opening/closing actions. This eliminates the need for users to physically touch door handles or surfaces, thereby maintaining high access control efficiency while preventing contamination transmission in high-traffic areas.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If professional installation and configuration is required for door access control systems, then system reliability is improved, but installation complexity and time increase

Engineering Contradiction:

Improvesystem reliabilityVSAvoidinstallation ease

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent implements self-configuration capabilities where the door access control system automatically detects and adapts to the installation environment, performs self-calibration, and configures operational parameters without requiring professional technicians. The system includes automated setup routines that guide users through installation steps and automatically adjust settings based on detected door type, traffic patterns, and environmental conditions, thereby maintaining system reliability while dramatically simplifying installation.

Inventive Principle:

Principle #25Self-service

3Difficulty of detecting and measuring

If traditional sensor-based automatic door control is used, then object detection capability is improved, but the ability to understand user intent and authentication is lost

Engineering Contradiction:

Improveobject detection capabilityVSAvoiduser intent understanding

Core Design Contradiction:

Difficulty of detecting and measuringVSLoss of information

Solution Approach 1:

The patent merges multiple detection and authentication technologies into a unified system that combines traditional sensors for object detection with cameras for facial recognition, microphones for voice commands, and wireless communication modules for digital authentication. This integrated approach allows the system to not only detect the presence of objects but also understand user intent through multiple modalities and verify authentication credentials, thereby preserving both detection capability and information understanding.

Inventive Principle:

Principle #5Merging (Combining)

4Object-affected harmful factors

If touch-free operation is implemented, then hygiene and safety are improved, but system complexity and power consumption increase

Engineering Contradiction:

Improvehygiene and safetyVSAvoidpower consumption

Core Design Contradiction:

Object-affected harmful factorsVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic sensing and touch-free operation modes where the system activates sensors and actuators only during detected user approach events rather than continuously. The system uses low-power sleep modes between activation cycles, with sensors triggering brief periods of high-power operation for door actuation followed by return to low-power state. This periodic operation pattern maintains hygiene and safety through touch-free functionality while significantly reducing overall power consumption compared to continuous operation.

Inventive Principle:

Principle #19Periodic action
