Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If batteries are arranged above the rotary coupling on the rotating turret, then electrical power can be supplied to the rotating assembly, but the rotary coupling must be oversized to transmit power, rendering the solution impractical, expensive, and structurally complex
Solution Approach 1:
The battery system is segmented into two separate batteries: a first battery arranged below the rotary coupling on the vehicle chassis, and a second battery arranged above the rotary coupling on the rotating assembly. This segmentation allows each battery to be positioned optimally without requiring the rotary coupling to be oversized for power transmission, thereby reducing structural complexity while maintaining electrical power supply capability.
2Use of energy by moving object
If batteries are arranged above the rotary coupling, then electrical power can be supplied to the rotating assembly, but the available space is excessively occupied
Solution Approach 1:
The battery system is divided into two separate units positioned in different spatial zones: the first battery is arranged below the rotary coupling on the vehicle chassis, utilizing undercarriage space, while the second battery is arranged above the rotary coupling on the rotating assembly. This segmentation optimizes space utilization by distributing battery volume across different regions, avoiding excessive occupation of any single area.
3Object-generated harmful factors
If internal combustion engine is replaced with electric motor, then pollutant emissions are drastically reduced, but suitable placement for batteries becomes difficult due to limited space
Solution Approach 1:
The battery system is segmented into two separate batteries positioned in different locations: one below the rotary coupling on the vehicle chassis and another above the rotary coupling on the rotating assembly. This segmentation creates suitable placement for batteries by utilizing otherwise underutilized space in both the stationary and rotating portions of the system, enabling electric motor replacement while maintaining compact overall dimensions.
Solution Approach 2:
The battery arrangement extends into the vertical dimension by placing one battery below the rotary coupling and another above it, effectively utilizing the height dimension of the system. This dimensional approach creates adequate space for battery placement without increasing the horizontal footprint, allowing electric motor integration while maintaining compact ground-level dimensions.
