Ignition Coil Condenser Integration for Noise and Heat Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ignition coils face challenges in effectively removing noise and preventing water ingress due to the long distance between the ignition coil and the condenser, which affects noise dissipation.
Innovation Solution
A small condenser is directly installed to the low voltage pin of the ignition coil, and a waterproof and breathable fiber cover is inserted through insert molding to dissipate heat and prevent water ingress, with a ground pin connected to the vehicle body or head cover for enhanced noise removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the condenser is installed at a long distance from the ignition coil, then the installation flexibility is improved, but the noise removal effectiveness deteriorates
Solution Approach 1:
The patent merges the condenser with the ignition coil assembly by installing it on the LV pin within the outer casing, creating an integrated noise removal system that maintains effectiveness while preserving installation flexibility
2Reliability
If the cover material is made impermeable to prevent water ingress, then the waterproofing is improved, but the heat dissipation capability deteriorates
Solution Approach 1:
The patent employs waterproof and breathable fiber material in the cover that contains porous structure, allowing heat to pass through while blocking water ingress, thus simultaneously achieving waterproofing and heat dissipation
Solution Approach 2:
The cover is constructed using composite material combining waterproof and breathable fiber with heat dissipation properties, integrating multiple functions into a single component
3Volume of moving object
If the condenser size is reduced for compact installation, then the installation space requirement is improved, but the noise removal capacity deteriorates
Solution Approach 1:
The patent optimizes the condenser parameters including capacitance value and physical dimensions to achieve the required noise removal capacity in a compact size, balancing space constraints with functional effectiveness
