Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If torque transmission is increased to improve power delivery, then power transmission capability is improved, but energy consumption increases and component damage risk increases
Solution Approach 1:
The patent employs a shift mechanism with a shift collar that can dynamically change gear ratios (between gear 202 and gear 204) to adapt torque transmission to varying operational conditions. This dynamic adjustment allows the system to optimize the balance between power transmission and energy consumption by selecting appropriate gear ratios based on load requirements
Solution Approach 2:
The patent changes the transmission ratio parameter through the shift mechanism, allowing variation between different gear ratios. This parameter change enables the system to reduce energy consumption during low-load conditions while maintaining adequate power transmission capability when needed
2Power
If torque transmission is increased to improve power delivery, then power transmission capability is improved, but component damage risk increases
Solution Approach 1:
The shift mechanism provides dynamic control over torque transmission by allowing the shift collar to engage different gears (202, 204) based on operational conditions. This dynamic adjustment prevents excessive torque from damaging components by selecting appropriate gear ratios that limit peak torque transmission
Solution Approach 2:
The gear reduction module with multiple gears provides beforehand cushioning by distributing torque through different transmission paths. The shift mechanism can pre-select lower gear ratios to cushion against potential torque spikes before they reach the components, reducing damage risk
3Loss of energy
If gear ratios are changed to reduce energy consumption, then energy efficiency is improved, but torque transmission control complexity increases
Solution Approach 1:
The transmission system is segmented into distinct gears (202, 204) and a shift mechanism with a shift collar. This segmentation allows independent control of each gear stage, simplifying the overall control logic by breaking down the complex torque transmission into manageable, discrete gear selection decisions
Solution Approach 2:
The shift collar acts as an intermediary element that mediates between the input shaft and different gears (202, 204). This intermediary mechanism simplifies control by providing a single point of actuation that automatically engages the appropriate gear based on operational conditions, reducing the complexity of direct control

AI summary
A torque transmission apparatus having a shift collar and a drive component. The shift collar may have a collar gear that may have a collar tooth that may have a concave collar tooth side surface that may be centered about a transverse collar tooth plane. The drive component may have a tooth that may have a convex lateral side surface centered about a transverse tooth plane. The concave collar tooth side surface may cooperate with the convex lateral side surface to align the transverse collar tooth plane with the transverse tooth plane.
