Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The complexity and cost of replacing vehicle keys, particularly due to the integration of advanced security features like transponders and rolling codes, make it difficult for consumers to obtain replacement keys without visiting a dealership or locksmith, leading to high costs and inconvenience.

Innovation Solution

A system and method for capturing images of a master key using a handheld device or kiosk, processing the image to determine key bitting information, and cutting a replacement key based on this data, which is then shipped to the user, optionally including transponder programming, to facilitate remote key replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If advanced security features like transponders and rolling codes are integrated into vehicle keys, then vehicle security is improved, but the complexity and cost of key replacement increases

Engineering Contradiction:

Improvevehicle securityVSAvoidkey replacement complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system separates key replacement into distinct modules: image capture device for data collection, processing system for extracting key features and bitting information, and cutting system for manufacturing. This segmentation allows each component to specialize in one function, reducing overall system complexity while maintaining security features.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system creates a digital copy of the master key through image capture and processing, storing key features and bitting information electronically. This digital copying eliminates the need for physical key duplication at dealerships, simplifying the replacement process while preserving security through encrypted data transmission and controlled access to the digital key repository.

Inventive Principle:

Principle #26Copying

2Reliability

If advanced security features like transponders and rolling codes are integrated into vehicle keys, then vehicle security is improved, but the cost of key replacement increases

Engineering Contradiction:

Improvevehicle securityVSAvoidkey replacement cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The system replaces traditional mechanical key cutting and programming processes with automated image-based capture and digital processing. Instead of requiring specialized mechanical equipment and manual programming at dealerships, the system uses optical imaging and software-based key feature extraction, significantly reducing equipment costs and operational expenses.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables consumers to perform key replacement themselves by capturing images of their master key using portable devices and following automated processing instructions. This self-service approach eliminates the need to visit dealerships or locksmiths, reducing service costs while maintaining security through validated image processing and controlled key generation.

Inventive Principle:

Principle #25Self-service

3Manufacturing precision

If consumers visit dealerships or locksmiths for key replacement, then key accuracy is ensured, but convenience is reduced

Engineering Contradiction:

Improvekey cutting accuracyVSAvoidkey replacement convenience

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The system introduces an automated image processing intermediary that acts as a bridge between the consumer and key manufacturing. The processing system validates captured images, extracts key features, and generates cutting instructions automatically, ensuring accuracy equivalent to professional services while allowing consumers to complete the process at home without visiting dealerships or locksmiths.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Device complexity

If image processing is used to capture key information, then the need for physical key duplication equipment is reduced, but image processing accuracy must be ensured

Engineering Contradiction:

Improveequipment requirementVSAvoidkey feature detection accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The system performs preliminary actions by capturing multiple images of the master key from different angles and positions before processing. The image processing system pre-validates image quality, automatically adjusts for lighting and angle variations, and pre-extracts key features to ensure accurate bitting information is obtained before key cutting begins, eliminating the need for complex physical measurement equipment.

Inventive Principle:

Principle #10Preliminary action
