Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional computer mice with simple digital signal output are used, then the device structure is simple, but the measurement precision of pressure and fine operating movements cannot be achieved
Solution Approach 1:
The patent replaces traditional mechanical pressure sensors with a magnetic sensing system. A magnetic element is embedded in the palm rest cover while a magnetic sensor is placed on the main body, detecting magnetic field changes as the palm rest cover moves. This substitution eliminates complex mechanical contact mechanisms while achieving precise pressure and position sensing through non-contact magnetic field detection.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the user's hand pressure and the sensing system. The magnetic element modulates the magnetic field in response to palm rest cover displacement, and the magnetic sensor detects these field variations. This intermediary approach enables indirect but precise measurement of pressure and position without direct mechanical contact between sensing components.
2Adaptability or versatility
If conventional computer mice without pressure sensing are used, then the ease of operation is maintained, but the adaptability for video games requiring fine operating movements is insufficient
Solution Approach 1:
The patent integrates multiple functions into a single device structure. The swingable palm rest cover with embedded magnetic element serves both as an ergonomic support surface and as an active sensing component. The magnetic sensing system simultaneously detects both the position and pressure of the palm rest cover, enabling the mouse to function for both general computing tasks and precision video game operations without requiring separate specialized devices.
Solution Approach 2:
The patent transforms the static palm rest cover into a dynamic sensing element. The palm rest cover is designed to swing or move in response to user hand pressure and wrist movements, and this dynamic motion is captured by the magnetic sensor. The system continuously tracks the changing position and force applied, enabling real-time adaptation to user inputs for fine operating movements in video games.
3Measurement precision
If a swingable palm rest cover with magnetic sensor is added, then the measurement precision of pressure sensing is improved, but the device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical pressure sensors with a magnetic sensing system. A magnetic element is embedded in the palm rest cover while a magnetic sensor is placed on the main body, detecting magnetic field changes as the palm rest cover moves. This substitution eliminates complex mechanical contact mechanisms while achieving precise pressure and position sensing through non-contact magnetic field detection.

Function Achieved in This Case
Enhances operating precision and convenience by enabling users to control pressing force with wrist movements, improving gameplay accuracy in games requiring fine movements.
Implementation Method 1
The magnetic sensor is disposed on one of the upper housing and the palm rest cover. The magnetic sensor is electrically connected to the circuit board. The magnetic element is disposed on the other of the upper housing and the palm rest cover. When the palm rest cover is swung to left or to right, the magnetic sensor and the magnetic element are capable of sensing a position change of the palm rest cover, so as to output an analog signal.
Implementation Method 2
The magnetic sensor is a Hall effect sensor.
