Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional training methods and technician oversight are used, then device complexity and training requirements are minimized, but service quality consistency and safety are compromised due to human error

Engineering Contradiction:
Improveservice quality consistencyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces an augmented reality system as an intermediary between technicians and vehicle components. The AR device captures images of the vehicle, retrieves relevant service information, and overlays guidance instructions onto the technician's field of view. This intermediary system provides consistent, error-free guidance without requiring complex training programs or extensive oversight infrastructure.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system creates a virtual copy of the service guidance information and overlays it directly onto the physical vehicle components in the technician's view. By copying procedural information into the AR interface and aligning it with the actual vehicle parts, the system ensures technicians follow correct procedures without relying on memory or external references, thereby improving service quality consistency.

Inventive Principle:
Principle #26Copying

2Productivity

If technicians work rapidly to meet productivity benchmarks, then service speed increases, but mistakes such as forgetting components or procedures increase

Engineering Contradiction:
Improveservice speedVSAvoiderror rate
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The AR system provides continuous guidance information throughout the entire service procedure. As technicians move from one task to another, the system continuously updates the overlay information to reflect the current step, ensuring that guidance is always available without interrupting the workflow. This continuous information delivery allows technicians to maintain high speed while avoiding mistakes through constant procedural reinforcement.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system incorporates feedback mechanisms where the AR device monitors the technician's progress through image recognition and compares it against the expected procedure. When deviations are detected or steps are completed, the system provides immediate feedback through the overlay interface, confirming correct actions or alerting to missed components, thereby maintaining high reliability even at high productivity levels.

Inventive Principle:
Principle #23Feedback

3Reliability

If detailed training and certification programs are implemented, then technician competence improves, but training time and operational overhead increase

Engineering Contradiction:
Improvetechnician competenceVSAvoidtraining time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary action by pre-loading all necessary service procedures, specifications, and troubleshooting information into the AR device before the technician begins work. The system automatically retrieves and displays the specific guidance relevant to the current vehicle and task, eliminating the need for technicians to have memorized extensive training materials. This shifts the knowledge burden from training to the digital system, reducing training time while maintaining competence.

Inventive Principle:
Principle #10Preliminary action

AI summary

An environment association system ("EAS") comprising:a processor and a memory;an object recognition process configured to identify objects within images, the objects including one or more of a vehicle, a vehicle lift, a vehicle repair tool, and an alignment fixture; and an EAS interface configured to communicate with a user device, the user device comprising a camera and a display; wherein the processor is configured to: determine, for at least one object in the set of objects, create a virtual overlay for the image based on the position of the at least one object within the image and a virtual marking associated with the at least one object; and provide the virtual overlay to the user device, wherein the virtual overlay is configured to cause the user device to simultaneously display the image and the virtual overlay via the display. The system provides information about the alignment of lifting points of the object with lifting members.
