Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If current systems and methods are used to establish a connection between a mobile device and a vehicle, then the connection can be established, but the interaction process becomes complex and challenging for visually impaired occupants

Engineering Contradiction:

Improveease of connection establishmentVSAvoidinteraction complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces visual-based interaction mechanisms with auditory feedback mechanisms. The controller speaks identifiers and passcodes aloud through a speaker, and uses voice-activated microphones to detect commands, substituting the visual display and manual input system with an auditory channel that visually impaired occupants can utilize effectively

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an intermediary auditory feedback loop between the controller and the mobile device. The controller transmits identifiers and passcodes through auditory channels (speaker and microphone) rather than direct visual display, creating an intermediary communication layer that bridges the gap for visually impaired users

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If visual display methods are used to transmit connection identifiers and passcodes, then the information can be displayed, but visually impaired occupants cannot access the information

Engineering Contradiction:

Improveinformation accessibilityVSAvoidvisual impairment barrier

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent substitutes the visual display mechanism with an auditory output mechanism. The controller uses a speaker to vocalize connection identifiers and passcodes, transforming visual information into auditory information that can be perceived by occupants with visual impairments, thereby eliminating the barrier created by visual-only displays

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the fundamental parameter of information transmission from visual to auditory modalities. By converting the display parameter (visual) into an acoustic parameter (auditory), the system makes the information accessible to occupants with visual impairments while maintaining the same functional purpose of information transmission

Inventive Principle:

Principle #35Parameter changes

3Productivity

If manual input methods are required for connection confirmation, then the connection can be confirmed, but the process becomes time-consuming and cumbersome

Engineering Contradiction:

Improveconnection establishment speedVSAvoidconnection establishment time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent implements self-service through voice-activated confirmation. The controller uses voice-activated microphones to detect confirmation commands and automatically confirms the connection without requiring manual input from the occupant, thereby reducing the time and effort needed for connection establishment

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent introduces an auditory feedback loop for connection confirmation. The controller provides auditory feedback to confirm successful connection, and uses voice-activated microphones to detect user confirmation, creating a rapid bidirectional communication loop that accelerates the connection establishment process compared to manual methods

Inventive Principle:

Principle #23Feedback

AI summary

A system for establishing a wireless connection between a mobile device and a vehicle includes a human-machine interface (HMI), a vehicle communication system, where the vehicle communication system includes a wireless connection transceiver, a speaker, a microphone, a controller in electrical communication with the HMI, the vehicle communication system, the speaker, and the microphone. The controller is programmed to activate a wireless connection mode of the controller based at least in part on a signal from the microphone and transmit a vehicle wireless connection identifier using the speaker. The controller is further programmed to confirm a vehicle wireless connection passcode using at least one of the speaker and the microphone and establish a wireless connection between the mobile device and the controller using the wireless connection transceiver in response to confirming the vehicle wireless connection passcode.
