Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for installing aftermarket electronic devices in vehicle electrical systems require modifications to the existing wiring, which can be invasive and disruptive to the factory electrical setup.
Innovation Solution
A relay plug and fuse plug system that allows for the insertion into a vehicle's electrical system fuse box, providing a wiring harness that supplies voltage and ground to aftermarket devices without altering the existing wiring, using a relay plug in the starter relay socket and a fuse plug in a fuse slot, with electrical connections to the battery, enabling constant and switched voltage and ground circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing wiring is modified to install aftermarket electronic devices, then the devices can be integrated into the vehicle electrical system, but the factory electrical setup is disrupted and wiring complexity increases
Solution Approach 1:
The patent introduces a relay socket adapter as an intermediary device that connects between the vehicle's existing relay socket and the aftermarket electronic device. This adapter provides male electrical contacts that interface with the female contacts in the relay socket, enabling power and control signals to be transmitted without modifying the vehicle's original wiring. The intermediary adapter thus resolves the contradiction by facilitating integration while preserving the factory electrical setup.
Solution Approach 2:
The patent segments the integration function into separate modular components: the relay socket adapter, the relay plug, and the wiring harness. This segmentation allows each component to perform a specific function independently - the adapter interfaces with the existing socket, the relay plug provides electrical connections, and the harness routes power and signals. This modular approach reduces overall wiring complexity while maintaining adaptability for different aftermarket devices.
2Adaptability or versatility
If wiring modifications are made for aftermarket device installation, then device integration is achieved, but installation time and disruption to factory setup increase
Solution Approach 1:
The relay socket adapter is pre-configured with male electrical contacts and wiring harness connections before installation. The adapter is designed to directly interface with standard relay sockets, eliminating the need for on-site wiring modifications. This preliminary preparation of the adapter component enables rapid installation by simply plugging it into the existing socket, thereby reducing installation time while achieving full device integration.
Solution Approach 2:
The relay socket adapter serves as a pre-fabricated intermediary that bridges the vehicle's electrical system and the aftermarket device. By providing ready-made electrical contacts and wiring connections, the adapter eliminates time-consuming wiring modifications and allows for quick plug-and-play installation, thus resolving the contradiction between integration capability and installation time.
3Use of energy by moving object
If the relay plug is inserted into the starter relay socket, then constant and switched voltage are supplied to the aftermarket device, but the starter relay functionality must be maintained
Solution Approach 1:
The relay socket adapter is designed to provide multiple functions through a single device: it supplies constant voltage (battery power), switched voltage (ignition-controlled power), and ground connections to the aftermarket device, while simultaneously maintaining the starter relay's original functionality. The adapter's multiple electrical contacts interface with corresponding contacts in the relay socket, enabling it to serve both the aftermarket device and the vehicle's starting system universally.
Solution Approach 2:
The relay socket adapter acts as an intermediary that taps into the existing relay socket's electrical contacts to provide power and control signals to the aftermarket device without interfering with the starter relay's operation. The adapter's wiring harness routes signals appropriately to maintain the relay's original function while enabling the additional device to receive necessary voltage and ground connections.

AI summary
A vehicle wiring harness assembly for installing an aftermarket electronic device into a vehicle electrical system includes a relay plug that is insertable into a starter relay socket in a vehicle electrical system fuse box. The relay plug takes the place of the starter relay in the vehicle electrical system fuse box. A fuse plug is insertable into a fuse slot in the vehicle electrical system fuse box. Thus, the fuse plug is in electrical communication with the battery of the vehicle electrical system. A wiring harness is electrically coupled to each of the relay plug and the fuse plug. In this way the wiring harness can supply voltage and ground to an aftermarket electronic device without modifying existing wiring in the vehicle electrical system.
