Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a torque transmission component uses radially aligned bending webs, then it can transmit torque, but the component becomes larger and less compact
Solution Approach 1:
The torque transmission component is segmented into multiple discrete connecting webs arranged circumferentially around the axis. Each web is a separate structural element that contributes to the overall torque capacity, allowing the component to achieve high strength-to-volume ratio through distributed load bearing across multiple segments rather than requiring a single large radial structure.
Solution Approach 2:
The invention transitions from radially aligned webs to circumferentially arranged webs, changing the spatial dimension of force transmission. By orienting webs in the circumferential direction rather than radially, the component achieves more efficient space utilization and compactness while maintaining torque transmission capability through the circumferential force path.
2Measurement precision
If deformation measuring sensors are added to the torque transmission component, then precise torque measurement is enabled, but the device complexity increases
Solution Approach 1:
The deformation measuring sensors are merged directly into the connecting webs structure. The sensors are integrated as part of the web assembly, allowing torque measurement functionality to be combined with the structural torque transmission function. This integration approach enables precise measurement while minimizing additional complexity by using the existing web structure as the measurement platform.
Solution Approach 2:
The connecting webs serve dual functions: they transmit torque structurally and simultaneously serve as the mounting platform for deformation measurement. The webs' own deformation under load provides the measurement signal, eliminating the need for separate measurement systems and reducing overall device complexity while maintaining high measurement precision.
3Reliability
If the connecting webs are designed to be elastically deformable, then overload protection is provided, but the component may deform under normal operation
Solution Approach 1:
The connecting webs are pre-designed with elastic deformability to provide beforehand cushioning against overload conditions. By incorporating controlled elastic compliance into the web structure, the component can absorb excess energy during overload events through elastic deformation, protecting the transmission system from damage while maintaining structural integrity during normal operation within the elastic range.
Solution Approach 2:
The material and geometric parameters of the connecting webs are optimized to achieve the desired balance between stability and overload protection. By carefully selecting web dimensions, material properties, and cross-sectional characteristics, the component maintains sufficient rigidity for normal torque transmission while retaining enough elastic compliance to provide overload protection through controlled deformation under extreme conditions.
