Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surge absorbers are bulky and occupy significant space, making them unsuitable for compact electronic products, and they rely on hot melt soldering which is not efficient for quick disconnection during surge events.
Innovation Solution
A side-ejection surge absorber module with a conductive bracket elastically abutted by a torque spring, allowing the bracket to move horizontally and disconnect the surge absorbing member to create an open circuit, reducing module height and improving disconnection efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional surge absorber uses hot melt soldering to fix the metal bracket, then the bracket can be securely attached, but the disconnection process is slow and not efficient during surge events
Solution Approach 1:
The patent transforms the static hot melt connection into a dynamic system where the conductive bracket can rapidly move between connected and disconnected states. The elastic member enables the bracket to dynamically respond to surge conditions by automatically ejecting when the hot melt member melts, achieving both secure connection during normal operation and rapid disconnection during surges.
2Ease of operation
If the surge absorber is designed with traditional longitudinal ejection, then the disconnection function is achieved, but the module height becomes too large for compact electronic products
Solution Approach 1:
The patent changes the ejection direction from the vertical dimension (longitudinal) to the horizontal dimension (lateral). The conductive bracket is designed to move sideways along the electrode surface rather than ejecting vertically, which maintains the disconnection function while significantly reducing the module height to enable compact electronic product designs.
3Reliability
If the conductive bracket is fixed firmly to ensure stable connection, then connection reliability is improved, but the bracket cannot be quickly disconnected when surge occurs
Solution Approach 1:
The patent utilizes the phase transition of the hot melt member from solid to liquid when exposed to surge heat. During normal operation, the hot melt member is solid and provides strong bonding. When a surge occurs, the rapid heating causes it to melt and transition to liquid state, releasing the conductive bracket which is then ejected by the elastic member, achieving both stable connection and rapid disconnection.

AI summary
A surge absorber module includes a conductive bracket with an end fixed to a main body and electrically connected to a pin, and the other end electrically connected to a surge absorbing member through a hot melt member, and an elastic member with an end elastically abutting the main body and the other end elastically abutting the conductive bracket. The conductive bracket is elastically abutted by the elastic member to move horizontally in an accommodating space and disconnect the electrically connected surge absorbing member.
