Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the wireless charger is placed at one side of a shawl and counterweights are placed at the other side to align the charger with the brain pacemaker, then the alignment accuracy is improved, but the charging efficiency deteriorates when the charger is deflected or at a greater distance
Solution Approach 1:
The patent changes the physical parameters of the charging system by introducing a signal gain module that amplifies the charging signal. This allows the system to maintain reliable charging efficiency even when alignment is not perfect or distance increases, as the amplified signal compensates for signal loss due to deflection or distance
Solution Approach 2:
The patent makes the charging system more dynamic by enabling it to adapt to varying distances and angles through signal amplification. The signal gain module dynamically compensates for changes in alignment and distance, allowing the charger to maintain effectiveness across a range of positions rather than requiring precise static alignment
2Ease of operation
If the distance between the wireless charger and brain pacemaker is increased, then the ease of operation is improved, but the charging efficiency deteriorates
Solution Approach 1:
The patent changes the signal strength parameter through the signal gain module, which amplifies the charging signal to compensate for increased distance. This allows users to operate the charger at greater distances from the pacemaker while maintaining sufficient charging efficiency, thereby improving ease of operation without sacrificing reliability
3Measurement precision
If a complex alignment system with counterweights is used to ensure accurate positioning, then the alignment precision is improved, but the device complexity increases
Solution Approach 1:
The patent changes the approach from mechanical alignment (using counterweights and precise positioning) to signal-based compensation. The signal gain module amplifies the charging signal to overcome misalignment and distance issues, eliminating the need for complex mechanical alignment systems while maintaining charging effectiveness

Implementation Method 1
The first conductive wire, arranged on the upper surface of the insulation substrate, outwardly makes at least one turns around the first buffer portion. The second conductive wire whose position corresponds to the position of the first conductive wire, arranged on the lower surface of the insulation substrate, outwardly makes at least one turns around the second buffer portion.

AI summary
A wireless charging device includes a wireless charging transmitter transmitting a charging signal to a signal gain module to generate at least one gain signal. The signal gain module includes an insulation substrate with an upper surface thereof provided with a first conductive wire. The first conductive wire makes at least one turns arranged along the inner edge of the insulation substrate. The lower surface of the insulation substrate is provided with a second conductive wire whose position corresponds to the position of the first conductive wire. A connecting element is arranged between the first conductive wire and the second conductive wire, such that the first conductive wire is electrically connected to the second conductive wire through the connecting element. The present invention provides a charging signal with high intensity to avoid the low charging efficiency caused by deflection and too long a distance.
