Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the anode and cathode are made with different lengths to improve battery capacity, then the battery capacity increases, but magnetic interference is generated between the battery and speaker
Solution Approach 1:
The patent converts the harmful magnetic field generated by the length difference between anode and cathode into a beneficial cancellation mechanism. By intentionally designing the conductive member with specific geometry and electrical connection, the magnetic field generated by the conductive member cancels out the unwanted magnetic field from the battery, transforming the harmful effect into a useful noise-cancellation function.
Solution Approach 2:
The conductive member acts as an intermediary element between the battery and speaker. It is electrically connected to the battery terminals and positioned between the battery and speaker to generate a counteracting magnetic field. This intermediary structure mediates the magnetic interaction, preventing direct magnetic interference while maintaining electrical connectivity for power supply.
2Object-affected harmful factors
If a conductive member is added to cancel the magnetic field, then magnetic interference is reduced, but the device complexity increases
Solution Approach 1:
The conductive member is designed to serve multiple functions simultaneously: it provides electrical connection between the battery terminals, acts as a magnetic field cancellation element, and can serve as a structural support component. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving magnetic interference reduction.
Solution Approach 2:
The patent merges the electrical connection function and magnetic field cancellation function into a single conductive member. Rather than adding a separate cancellation component, the design integrates the magnetic cancellation capability into the existing electrical connection structure, combining multiple functions into one element to minimize added complexity.
