Motorcycle Ignition Coil Assembly Eliminating External Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ignition coil systems for motorcycles often result in clutter and suboptimal performance due to the need for high-voltage insulated wires connecting the ignition coil to spark plugs, exposing these wires to harsh environments.
Innovation Solution
An ignition coil assembly is designed with a direct mounting configuration proximate to the spark plugs, eliminating the need for external wiring by using an ignition coil cover, boot, and mounts that securely position the ignition coil in a plug recess, concealing the wiring within the engine's structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ignition coil is positioned remotely from spark plugs and connected by high-voltage insulated wires, then installation flexibility is improved, but current leakage and electronic interference increase
Solution Approach 1:
The ignition coil is integrated directly with the spark plug by positioning it in close proximity and eliminating the external wiring connection. The ignition coil housing is mounted directly on the engine cylinder head near the spark plug, creating a combined assembly that reduces current leakage and electronic interference while maintaining installation flexibility through the unified design.
2Adaptability or versatility
If ignition coil is positioned remotely from spark plugs, then wiring routing flexibility is improved, but exposure to harsh environments increases
Solution Approach 1:
The ignition coil and spark plug are positioned as an integrated assembly with the ignition coil housing mounted directly on the engine cylinder head. This merging eliminates the need for separate wiring routing while protecting the ignition components from harsh environmental conditions by consolidating them in a controlled mounting location.
3Object-generated harmful factors
If coil-on-plug design is implemented, then current leakage and electronic interference are reduced, but engine structural compatibility requirements increase
Solution Approach 1:
The ignition coil housing is designed to be mounted directly on the engine cylinder head in close proximity to the spark plug, creating a coil-on-plug configuration. This integrated design reduces current leakage and electronic interference while the universal mounting features and adaptable housing design allow compatibility with various engine types.
Solution Approach 2:
The ignition coil assembly is designed with universal mounting features that can accommodate different engine configurations. The housing includes mounting brackets and attachment points that can be adapted to various engine cylinder heads, making the design versatile across different motorcycle engine types while maintaining the coil-on-plug benefits.

Function Achieved in This Case
This configuration reduces current leakage and electronic interference, providing a cleaner and more efficient ignition system by eliminating external wiring and enhancing the aesthetic and functional integration with the motorcycle engine.
Implementation Method 1
Ignition coils are induction coils that cooperate with a vehicle's battery to provide the energy required to power spark plugs. Specifically, the ignition coil typically converts relatively low voltage current from the vehicle's battery to the high voltage current required to generate a spark
