Aftermarket Interface Module Configuration via GUI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aftermarket entertainment systems typically do not function with OEM vehicle controls without a specific interface, and existing interfaces are limited to pre-loaded configurations, becoming outdated with new electronics and vehicle models, and fail to fully utilize OEM controls' functionality.
Innovation Solution
A system and method using a graphical user interface (GUI) to configure an aftermarket interface module, allowing users to select vehicle and electronics information to generate a control signal configuration, enabling OEM controls to operate aftermarket electronics, with the ability to assign multiple functions to each OEM control button.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If pre-loaded configurations are used in interface modules, then configuration speed is improved, but adaptability to new electronics and vehicles deteriorates
Solution Approach 1:
The interface module performs preliminary actions by automatically detecting vehicle and electronics parameters during installation, then uses this information to generate an optimized control signal configuration without requiring pre-loaded configurations or manual installer sequencing. This resolves the contradiction by eliminating the need for pre-loaded configurations while maintaining fast configuration through automated parameter detection and configuration generation.
2Manufacturing precision
If extensive sequencing procedures are used for configuration, then configuration precision is improved, but ease of operation deteriorates
Solution Approach 1:
The interface module performs self-service by automatically detecting vehicle parameters, electronics characteristics, and generating optimized control signal configurations without requiring installer intervention or complex sequencing procedures. The system configures itself based on detected parameters, resolving the contradiction by eliminating manual sequencing while maintaining configuration accuracy through automated detection and generation processes.
3Adaptability or versatility
If multiple functions are assigned to OEM controls, then functionality is improved, but device complexity increases
Solution Approach 1:
The system changes parameters by dynamically generating control signal configurations based on detected vehicle and electronics parameters, allowing multiple aftermarket electronics functions to be assigned to OEM controls without increasing physical device complexity. The interface module adapts the control signal parameters to enable full functionality while maintaining a simple physical interface structure.
Data Source
AI summary
A system to remotely configure an aftermarket interface module using a graphical user interface (“GUI”) is disclosed. The system includes a GUI adapted to display on a computer. The GUI permits a user to select a vehicle model, year and make to determine the functions of the OEM controls. In addition, the GUI permits a user to select an aftermarket electronics brand and model that the OEM controls will operate. The user selects a particular control signal configuration using the GUI for each of the OEM controls. An interface module is flash programmed with the particular control signal configuration. The interface module is connected to the OEM controls and the aftermarket electronics, where the interface module receives the OEM control signals and controls the aftermarket electronics using the particular control signal configuration.
