Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-position torque sensor is used, then the structure is simple, but the sensor cannot adapt to varying shaft diameters and loses sensitivity
Solution Approach 1:
The patent implements a dynamically adjustable platform that can change its position along the vertical axis to adapt to different shaft diameters. The platform includes adjustable support arms with telescopic mechanisms that can extend or retract, allowing the sensor to maintain optimal positioning regardless of the shaft size being measured
Solution Approach 2:
The adjustable platform is designed to accommodate multiple shaft diameters using a universal configuration. The support structure includes interchangeable components and adjustable linkages that can be reconfigured for different measurement scenarios, making a single device suitable for various applications
2Measurement precision
If the sensor position is fixed, then the manufacturing is simple, but the sensitivity and resolution are reduced
Solution Approach 1:
The platform incorporates adjustable positioning mechanisms that allow the sensor to be dynamically repositioned to optimal locations for maximum sensitivity. The support arms can be adjusted along guided rails to achieve precise positioning while maintaining manufacturing simplicity through standardized components
Solution Approach 2:
The system allows change in geometric parameters of the platform configuration, such as the length and angle of support arms, to optimize sensor positioning for different measurement requirements. These parameter adjustments are achieved through simple mechanical means like threaded adjustments or pinned connections
3Adaptability or versatility
If an adjustable mechanism is added to the platform, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The platform is divided into modular segments that can be independently adjusted. Each support arm is a separate module with its own adjustment mechanism, allowing localized adaptation without affecting the entire structure. This segmentation simplifies the overall complexity by breaking down the adjustment system into manageable, identical modules
Solution Approach 2:
The adjustment mechanisms use simple dynamic elements such as telescopic arms with pinned joints and threaded rods for position control. These dynamic components allow continuous adjustment while maintaining structural integrity, achieving adaptability through straightforward mechanical means rather than complex systems

AI summary
A torque sensor includes an adjustable platform vertically adjustable to place a sensing module near a rotating target to obtain measurements there from with a sensing element. The apparatus can be configured to include a bottom channel mounted to a base and a PCB tray mounted to a top channel, the PCB tray and top channel vertically adjustable from the base by a rotating shaft. The top and bottom channels are coupled to side bars and side channels in pairs movably connected by joint pins with a rotatable shaft movably connecting said joint pins. The sensing module is movable with respect to the base via rotation of said rotatable shaft causing movement of said pair of side bars and side channels, placing said sensing element nearest a target to obtain rotational movement data.
