Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple magnets are added to the charging device and electronic device to increase attractive force, then the connection stability is improved, but the device complexity and interior space requirement increase
Solution Approach 1:
The patent divides the magnetic attraction function into two separate components: a first magnetic member in the charging device and a second magnetic member in the electronic device. This segmentation allows each component to have a simpler structure while collectively providing sufficient attractive force for stable connection.
Solution Approach 2:
The patent introduces a non-magnetic layer between the magnetic members to create a layered structure. This dimensional arrangement optimizes the magnetic field distribution and attractive force without requiring multiple magnets, thereby simplifying the overall structure.
2Reliability
If multiple magnets are added to the charging device and electronic device to increase attractive force, then the connection stability is improved, but the interior space requirement increases
Solution Approach 1:
By separating the magnetic members into different devices (first magnetic member in charging device, second magnetic member in electronic device), each component can be miniaturized to fit within limited space constraints while collectively providing adequate attractive force.
Solution Approach 2:
The introduction of a non-magnetic layer creates a compact layered structure that maximizes magnetic attraction within minimal space, allowing the electronic device to maintain small dimensions while ensuring stable connection.
3Reliability
If strong magnetic attraction is used to secure the electronic device, then the connection stability is improved, but the ease of detachment deteriorates
Solution Approach 1:
The non-magnetic layer creates a controlled magnetic field distribution that provides strong holding force during normal use but allows for easy detachment when force is applied, optimizing both connection stability and operational convenience.
