Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electrical wiring systems in outdoor power equipment, such as riding lawn mowers, are inflexible, expensive, and difficult to modify, lacking programmability and data collection capabilities, which limits the ability to easily add or remove components and features.
Innovation Solution
A modular wiring harness system that connects switches in parallel with a primary control module, enabling easy addition or removal of components and features, and incorporates transceiver modules for data communication and smart technology to determine the state of switches, along with Bluetooth connectivity for remote monitoring and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional wiring systems are used with custom-designed routing for each model, then the electrical system can be tailored to specific vehicle requirements, but the flexibility to add or remove components is limited and redesign is required for any modifications
Solution Approach 1:
The wiring system is divided into modular control modules that can be independently added or removed. Each control module has standardized connections, allowing flexible configuration without redesigning the entire wiring system. This segmentation enables easy customization while maintaining system manageability.
Solution Approach 2:
The patent implements universal control modules with standardized interfaces that can serve multiple functions across different vehicle models. These modules can be configured for various electrical control tasks, providing adaptability without requiring custom wiring designs for each application.
2Adaptability or versatility
If switches are added or removed from conventional wiring systems, then system functionality can be modified, but the wiring harness must be completely redesigned and this interferes with system functionality due to component interdependencies
Solution Approach 1:
The control system is segmented into independent control modules that can be individually manufactured and assembled. This allows switches and other components to be added or removed by simply connecting or disconnecting modules rather than redesigning the entire wiring harness, significantly easing manufacturing and customization.
Solution Approach 2:
Control modules are pre-configured and pre-tested before being integrated into the vehicle system. This preliminary preparation allows for quick assembly and modification without requiring complex field wiring changes, improving both manufacturing efficiency and system reliability.
3Loss of information
If conventional wiring systems are used without data collection capabilities, then the system remains simple, but the working status of components cannot be monitored
Solution Approach 1:
The control modules incorporate feedback mechanisms that continuously monitor and report the working status of electrical components. This feedback capability provides real-time information about system health and component operation without significantly increasing overall system complexity, as the monitoring is integrated into the existing control architecture.
