Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mouse buttons are used for frequent gaming operations, then the buttons become depleted and unresponsive, but increasing manufacturing complexity and costs to improve durability
Solution Approach 1:
The patent applies the dynamics principle by making the prestress force adjustable rather than fixed. The prestress regulating structures allow users to dynamically adjust the prestress force applied to the button unit, enabling the mouse to adapt to different usage conditions and user preferences. This dynamic adjustment mechanism improves button responsiveness without requiring complex manufacturing structures, as it uses simple regulating rods and elastic elements that can be easily manufactured.
2Reliability
If prestress force is increased to improve button responsiveness, then button performance improves, but the structure becomes more complex and production costs increase
Solution Approach 1:
The patent applies segmentation by dividing the prestress regulation function into separate, independent prestress regulating structures for each button. Each regulating structure consists of simple components (regulating rod, tube, elastic element) that can be manufactured independently and assembled separately. This modular segmentation simplifies the manufacturing process and reduces production costs compared to a single complex integrated system, while still achieving improved button responsiveness through adjustable prestress force.
Solution Approach 2:
The patent applies parameter changes by enabling adjustment of the prestress force parameter through the regulating rod mechanism. Users can change the prestress force parameter to optimize button responsiveness for different gaming conditions or personal preferences. This parameter adjustability improves reliability without permanently increasing manufacturing complexity, as the same simple structure can accommodate a range of prestress force values.

Function Achieved in This Case
The mouse device effectively reflects user operation techniques with adjustable prestress forces, maintaining simplicity and reliability while reducing production costs, ensuring responsive button performance.
Implementation Method 1
A spring having a first contact and a second contact portion. The button unit connects to the first contact portion, and the projection portion abuts against the second contact portion.
Implementation Method 2
A first elastic element is placed around the push rod and located between the upper opening and the flange. A second elastic element is placed around the push road and located between the lower opening and the flange.

AI summary
A mouse device with prestress regulating structures has a body with a space, a printed circuit board and a micro switch are disposed in the space. The micro switch is electrically connected to the printed circuit board. A button unit is disposed in the body by means of a shaft and is available to move up and down relative to the body. The button unit has a first end and a second end and is configured to engage with the micro switch. A first prestress regulating structure is accommodated in the space and abutted against the bottom side of the first end for regulating a first prestress force applied to the first end. A second prestress regulating structure is accommodated in the space and abutted against the bottom side of the second end for regulating a second prestress force applied to the second end.
