Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual calibration of motorized units is performed at elevated locations, then precise door positions can be set, but operator safety is compromised and the process becomes cumbersome

Engineering Contradiction:

Improvedoor position calibration accuracyVSAvoidoperator safety hazard

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

A wireless control device serves as an intermediary between the operator and the motorized door unit. The operator can calibrate door positions from ground level by wirelessly transmitting calibration commands to the motorized unit, eliminating the need to physically access elevated locations while maintaining calibration precision through feedback from position sensors.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical control system (requiring physical presence at the motorized unit) with a wireless electronic control system. Calibration commands are transmitted wirelessly to the motorized unit, and position feedback is received wirelessly, substituting mechanical interaction with electronic communication to eliminate safety hazards.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If manual calibration operations are required at elevated locations, then precise target positions can be established, but the calibration process becomes time-consuming and complex

Engineering Contradiction:

Improvetarget position setting accuracyVSAvoidcalibration time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The wireless control device acts as a mediator that streamlines the calibration process. Operators can initiate calibration sequences from ground level, and the system automatically manages the multi-step calibration process including motorized unit movement and position verification, significantly reducing calibration time while maintaining precision.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The motorized door unit performs self-calibration by automatically moving to target positions and providing position feedback through sensors. The system autonomously completes calibration operations based on wireless commands, eliminating the need for manual intervention at elevated locations and reducing overall calibration time.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If controls are mounted on the motorized unit at elevated locations, then direct operation is possible, but operator accessibility is reduced and safety risks increase

Engineering Contradiction:

Improvedirect control operationVSAvoidoperator safety hazard

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The wireless control device serves as a portable intermediary control interface that operators can use from ground level. It transmits control commands wirelessly to the motorized unit and receives position feedback, providing direct operational control without requiring physical proximity to the elevated motorized unit, thus maintaining ease of operation while eliminating safety hazards.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the fixed mechanical control interface (mounted on the motorized unit) with a wireless electronic control interface. Operators can issue control commands from any location within wireless range, and the motorized unit executes commands and provides feedback wirelessly, substituting mechanical control with electronic communication to improve accessibility and safety.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An automatic door control system includes a door element that rotates in response to a change in position of a door, a first door position sensor configured to output a position signal based on rotation of the door element, a controller and a control device. The controller incudes memory containing a target position corresponding to an intermediate position of the door between maximally open and maximally closed positions of the door, and a processor configured to monitor a current position of the door based on the position signal and stop rotation of the door element when the current position matches the target position. The control device is configured to set the target position in the memory through a wireless communication link with the controller.
