T-Harness Serial Data Connector for Vehicle Remote Starter Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing remote engine starters in vehicles are labor-intensive and costly due to the need for soldering and taping numerous wires, and the use of large, expensive connectors, which makes quick-connect T-harness systems less desirable despite their potential for faster installation.
Innovation Solution
A T-Harness connector system that utilizes serial data lines to convey data and vehicle state changes, allowing a remote starter system to be installed at a single physical connection point, using electronic ignition modules and microcontrollers to translate key cylinder signals into data packets sent along serial data lines, eliminating the need for individual wire connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soldering and taping methods are used to connect remote starter wires, then reliable electrical connections are achieved, but installation becomes labor-intensive and time-consuming
Solution Approach 1:
The patent divides the wiring system into modular T-harness components that pre-organize multiple wire connections into integrated units. This segmentation allows installers to connect complete functional groups rather than individual wires, maintaining connection reliability while dramatically reducing installation time and labor requirements.
Solution Approach 2:
The T-harness system performs preliminary organization and pre-connection of wires during manufacturing. Wires are pre-routed, pre-insulated, and pre-configured into T-harness assemblies before installation, eliminating the need for installers to perform time-consuming soldering and taping operations during vehicle installation.
2Adaptability or versatility
If T-Harness with large connectors is used to provide comprehensive wiring connections, then all vehicle electrical needs are met, but cost increases due to large connector size
Solution Approach 1:
The patent segments the comprehensive wiring system into multiple smaller T-harness modules, each handling specific electrical functions. This allows the system to provide complete wiring coverage through modular assembly rather than requiring single large, expensive connectors, reducing material costs while maintaining full adaptability.
Solution Approach 2:
The patent transitions from a single-dimension approach (one large connector) to a multi-dimensional modular architecture where multiple smaller connectors work together in series and parallel configurations. This dimensional change allows comprehensive wiring coverage to be achieved through distributed modular connections rather than concentrated large connectors.
3Productivity
If T-Harness is used to bridge vehicle connectors, then installation is faster, but physical attachment of 30-35 individual wires is still required
Solution Approach 1:
The patent merges multiple individual wire connections into integrated T-harness assemblies where wires are pre-connected and bundled together. This merging reduces the number of separate connection operations required during installation, as entire groups of wires are installed as unified modules rather than individual connections.
Solution Approach 2:
The T-harness system performs the complex wire attachment operations during manufacturing rather than during vehicle installation. All 30-35 individual wire connections are pre-established in the harness assembly, so during installation the installer only needs to connect the pre-assembled modules, dramatically reducing on-site labor while maintaining connection integrity.
Data Source
AI summary
In one embodiment there is a remote starter system for a vehicle having an ignition connected to vehicle controllers by a serial data interface. The remote starter system includes a T-Harness connector having at least a first, second, and third serial data connectors and a remote starter module. The remote starter module having at least a remote starter connector, wherein the first serial data connector of the T-Harness connector is coupled to the remote starter connector, and the second and third serial data connectors are separately coupled between the pair of interconnected vehicle serial data connectors. Data from the remote starter module is thereby communicated to the vehicle controller modules and the ignition module.
