Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for duplicating vehicle door lock inserts are limited to those with external machining and cannot effectively decode inserts with internal patterns.
Innovation Solution
A method using an electronic system with specific software to decode inserts by superimposing a network of lines on an image of the insert, selecting predetermined points of intersection, and converting these into a code, applicable to both internal and external machining patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image processing methods from existing patents are used, then external machining inserts can be decoded, but internal machining inserts cannot be decoded
Solution Approach 1:
The patent creates a universal decoding system that handles both externally machined and internally machined inserts through a single image processing methodology. The software platform is designed to accommodate different insert types by allowing customization of the reference line network configuration, making the system multi-functional rather than type-specific.
Solution Approach 2:
The patent changes the parameters of the reference line network (number of lines, spacing, orientation) to adapt to different insert types. For internal machining patterns, the software adjusts the line network density and configuration to properly intersect with the internal features, enabling decoding of previously unreadable insert types.
2Ease of operation
If a fixed reference line network is used, then the decoding process is simple, but it cannot accommodate different insert types
Solution Approach 1:
The reference line network transitions from a static, fixed configuration to a dynamic, adjustable configuration. The software allows the line network parameters to be modified based on the insert type being decoded, providing adaptability while maintaining ease of operation through automated adjustments.
Solution Approach 2:
The software performs preliminary analysis of the insert image to automatically determine the appropriate reference line network configuration before decoding begins. This preliminary action selects optimal line spacing, number, and orientation based on the detected insert type, simplifying the user process while ensuring compatibility.
3Measurement precision
If manual point selection is required for each intersection, then precise decoding is achieved, but time consumption increases
Solution Approach 1:
The software performs self-service by automatically identifying and selecting the relevant intersection points between the reference line network and the insert pattern. The system autonomously processes the image data to extract code information without requiring manual user intervention at each intersection point, maintaining precision while dramatically reducing time consumption.
Solution Approach 2:
The manual mechanical process of selecting each intersection point is replaced by an automated computational system. The software uses image processing algorithms to automatically detect, identify, and extract information from intersection points, substituting human manual operation with automated digital processing that maintains accuracy while eliminating time loss.
