Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed sensing unit is used in the mouse, then the device structure is simple, but the mouse cannot operate properly on various surfaces (e.g., transparent glass, different textures)
Solution Approach 1:
The mouse is divided into separable modules: a main body and a replaceable sensing unit. The sensing unit can be detached and replaced with different types (e.g., infrared, optical, laser) depending on the surface requirements, while the main body remains unchanged. This segmentation allows the mouse to adapt to various surfaces without redesigning the entire device.
Solution Approach 2:
The main body of the mouse is designed with universal features that can work with multiple types of sensing units. The containing slot and electrical interface are standardized to accommodate different sensing unit types, making the main body universally compatible across various sensing technologies and surface conditions.
2Adaptability or versatility
If multiple sensing elements are integrated into the mouse, then the adaptability to different surfaces is improved, but the device complexity increases
Solution Approach 1:
The electrical interface is designed to dynamically adapt to different sensing unit types. The setting unit allows the processor unit to configure the electrical interface parameters according to the detected sensing unit type, enabling the same physical interface to handle multiple sensing technologies through software configuration rather than hardware complexity.
Solution Approach 2:
The setting unit acts as an intermediary between the processor unit and the sensing unit. It detects the type of sensing unit installed and automatically configures the electrical interface parameters, serving as a mediator that simplifies the interaction between diverse sensing elements and the main body without requiring complex dedicated interfaces for each sensing type.
3Ease of operation
If the sensing unit is made replaceable, then the operational convenience on various surfaces is enhanced, but the device structure becomes more complex
Solution Approach 1:
The sensing unit is extracted as a separate, replaceable component from the main body. The containing slot is designed to securely hold the sensing unit while allowing easy insertion and removal. This extraction enables users to replace the sensing unit themselves based on surface requirements without needing to disassemble the entire mouse or seek professional service.

AI summary
A mouse with a replaceable sensing unit comprises a main body, a processor unit and a sensing unit. The main body has a containing slot and a first electrical interface. The first electrical interface is disposed in the containing slot. The processor unit is disposed in the main body, and coupled to the first electrical interface. The sensing unit is replaceably disposed in the containing slot of the main body, and the sensing unit is coupled to the first electrical interface when the sensing unit is disposed in the containing slot. The processor unit gets via the first electrical interface an input signal generated when the sensing unit senses the movement of the main body, and then relatively outputs a cursor control signal to a computer apparatus.
