Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed weight design is used in the computer mouse, then the manufacturing process is simple and device complexity is low, but the adaptability and user customization capability are limited
Solution Approach 1:
The patent implements a movable weight system where weights can be dynamically repositioned along a track within the mouse housing. This dynamic configuration allows the center of gravity to be adjusted according to user preferences, transforming a static device into an adaptable one without requiring complete redesign of the mouse structure
Solution Approach 2:
The weight system is segmented into multiple individual weights that can be independently positioned. Each weight can be placed at different locations along the track, allowing fine-grained adjustment of the center of gravity. This segmentation provides versatility while keeping each individual component simple
2Adaptability or versatility
If multiple weights are added to enable center of gravity adjustment, then adaptability improves, but the device complexity and structural complexity increase
Solution Approach 1:
The weight tray assembly serves multiple functions: it holds the weights, provides a track for weight positioning, incorporates detection mechanisms to identify weight positions, and interfaces with the mouse's control system. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity
Solution Approach 2:
The weights are contained within the mouse housing, and the weight tray is nested within the housing as well. The detection mechanism is integrated into the tray assembly. This nested arrangement consolidates multiple elements into a compact structure, minimizing the increase in overall device complexity
3Ease of operation
If motorized control is used to move weights, then ease of operation improves, but the use of energy and device complexity increase
Solution Approach 1:
The system includes detection mechanisms (such as optical sensors or contact switches) that automatically identify the positions of the weights on the tray. This self-detection capability eliminates the need for complex user input or calibration procedures, improving ease of operation while using minimal energy compared to continuous motor control
Solution Approach 2:
Rather than continuous motor operation, the system uses periodic or on-demand motor activation to reposition weights only when the user intends to adjust the center of gravity. The motor operates in short bursts to move weights to new positions, then remains inactive, significantly reducing overall energy consumption

AI summary
A mouse with a tunable center of gravity is disclosed. According to certain embodiments, the mouse includes a moveable weight system that is used to move one or more weights from one position to another in the computer mouse. The relocation of one or more weights from one position to another in the computer mouse changes the center of gravity of the computer mouse.
