Ceramic Sheet Isolation for Electronic Switch Spark Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic switch devices using resin dispensing for packaging are prone to spark generation when conductive elements separate, which can damage both internal components and the plastic housing, as resin dispensing lacks heat resistance and insulation effectiveness.
Innovation Solution
The use of ceramic sheets to isolate contact points between the device and the base board, preventing sparks from reaching the base board and protecting the device and housing from damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resin dispensing is used to package electronic elements, then insulating quality is improved, but heat resistance deteriorates and the material becomes brittle
Solution Approach 1:
The patent replaces resin dispensing with ceramic sheets as the packaging material. Ceramic is a composite material that provides both excellent insulating quality and superior heat resistance, eliminating the brittleness and heat sensitivity issues of resin while maintaining electrical insulation properties.
Solution Approach 2:
The invention changes the material parameter from organic resin to inorganic ceramic, fundamentally altering the thermal and mechanical properties. This parameter change enables the packaging to withstand high temperatures without becoming brittle, while maintaining effective electrical insulation.
2Reliability
If resin dispensing is used to isolate electronic elements, then insulating quality is improved, but the plastic housing becomes vulnerable to spark damage
Solution Approach 1:
The patent uses ceramic sheets instead of resin dispensing for isolation. Ceramic material inherently resists spark damage and high temperatures, protecting both the electronic elements and the plastic housing from spark-induced damage while maintaining insulating quality.
Solution Approach 2:
The ceramic sheet acts as an intermediary barrier between the electronic elements and the housing. It provides thermal and spark protection to the housing while maintaining electrical isolation, effectively mediating between the high-energy electronic components and the vulnerable plastic structure.
3Ease of manufacture
If conventional packaging methods are used, then manufacturing simplicity is maintained, but protection against spark-generated heat is insufficient
Solution Approach 1:
The invention changes the material parameter from resin to ceramic, which fundamentally improves heat resistance. While ceramic sheets require different handling than resin dispensing, the overall manufacturing process is simplified by eliminating the need for complex dispensing equipment and curing processes, while providing superior thermal protection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The ceramic sheets effectively prevent spark damage to the electronic switch device and its housing by isolating potential spark zones, enhancing insulation and heat resistance beyond resin dispensing methods.
Implementation Method 1
A first sheet made of isolating composite material is connected to a portion of the top of the base board... The first sheet isolates contact between the base board and the device
Implementation Method 2
the resin dispensing may become brittle and hard to have better insulation. Finally, the sparkles may still damage the plastic housing and the inside components... ceramic sheets effectively prevent spark damage... enhancing insulation and heat resistance
