Grounding Magnet Assembly for Reliable Jumper Cable Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional jumper cables often experience failed engine start attempts due to loose or improper connections, especially when the vehicle battery is located in remote and inaccessible areas, and can cause sparks or fires.
Innovation Solution
Incorporating a grounding magnet instead of the conventional black clamp to enhance connection reliability and safety by allowing secure attachment to dead metal surfaces, reducing the risk of bad connections and sparks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional black clamp is used to connect to the vehicle battery terminal, then the connection can be made, but the connection is often loose, improper, or creates sparks
Solution Approach 1:
The patent replaces the conventional mechanical clamp system with a magnetic attachment system. The magnetic clamp uses magnetic force to securely attach to the vehicle battery terminal or dead metal surfaces, eliminating the need for manual clamping and providing consistent, reliable electrical contact without sparks or loose connections.
Solution Approach 2:
The patent changes the attachment mechanism from mechanical friction-based clamping to magnetic field-based attachment. This parameter change allows for secure, spark-free connection by using magnetic force to hold the clamp firmly in place, ensuring reliable electrical contact regardless of terminal accessibility.
2Adaptability or versatility
If the vehicle battery is located in remote areas such as the trunk or under seats, then the battery installation is flexible, but the battery poles become inaccessible for proper clamp connection
Solution Approach 1:
The magnetic clamp is designed to attach to multiple surfaces including battery terminals and dead metal surfaces anywhere in the vehicle. This multi-functionality allows the jumper cable system to work regardless of battery location, whether the battery is in the engine compartment, trunk, or under seats, making the system universally applicable to various vehicle configurations.
Solution Approach 2:
The magnetic clamp acts as an intermediary that can attach to any dead metal surface in the vehicle, not just the battery terminal. This allows the electrical connection to be established at accessible locations near the battery rather than requiring direct access to the battery poles, solving the accessibility problem for remotely located batteries.
3Reliability
If a magnetic clamp is used instead of a conventional clamp, then connection reliability and safety are improved, but the device structure becomes more complex
Solution Approach 1:
The patent merges the attachment function and electrical connection function into a single magnetic clamp component. The magnetic clamp integrates the magnetic attachment mechanism with the electrical contact point, eliminating the need for separate attachment hardware and reducing overall system complexity despite the advanced attachment mechanism.

AI summary
An improved jump starter system where at least one negative clamp/clip for the system is replaced with a magnet to allow a user to easily place the magnet on a dead metal area of the vehicle for an improved electrical connection. The improved jump starter preferably incorporates at least one grounding magnet to replace the conventional negative clamp. The grounding magnet provides for an alternative and improved way for making electrical connection by the negative/neutral cable. The improved jumper system is particularly idea for use in the automotive industry where a jump start system is used where the vehicle battery is depleted, as the improved jump starter system uses a magnet connection which improves the success for an engine start by providing a solid connection and closing the circuit between the jump starter and the vehicle battery.
