Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a centralized robotic control system is used, then control functionality is achieved, but vehicle space is significantly reduced
Solution Approach 1:
The patent divides the centralized control system into multiple distributed robotic control units (RCUs), each capable of independent operation. Each RCU contains a processor, memory, and control circuits that can autonomously manage specific vehicle functions, eliminating the need for a single large centralized computer and thereby preserving vehicle space.
Solution Approach 2:
The patent transitions from a single-point (centralized) control architecture to a multi-point (distributed) architecture across the vehicle network. By distributing control functions across multiple spatial locations rather than consolidating them in one central location, the system maintains autonomous functionality while reducing the volume occupied by control hardware.
2Adaptability or versatility
If separate control packages are used for each function, then functional independence is achieved, but system complexity increases
Solution Approach 1:
The patent designs each RCU as a universal control unit capable of performing multiple functions through software configuration rather than requiring separate hardware for each function. The standardized interface and modular architecture allow the same physical unit to handle different control tasks, reducing overall system complexity while maintaining functional independence.
Solution Approach 2:
The patent implements dynamic functionality where RCUs can be reconfigured and reassigned based on operational needs. The system allows flexible allocation of control functions to different RCUs, enabling adaptability without requiring permanent dedicated hardware for each function, thus managing complexity through software-based dynamics rather than fixed hardware architecture.
3Reliability
If hardened control packages are used, then reliability is improved, but payload and cargo space are reduced
Solution Approach 1:
The patent segments the control system into small, distributed RCUs that can be strategically placed in available spaces throughout the vehicle rather than requiring large dedicated hardened enclosures. This segmentation allows the control functionality to be distributed in smaller units that occupy minimal space, preserving payload and cargo areas while maintaining reliability through redundancy and distribution.
Solution Approach 2:
The patent applies local quality by placing RCUs close to the systems they control, reducing communication delays and improving response time. This localized distribution allows each RCU to be small and efficiently positioned in available spaces rather than requiring large centralized hardened packages, thereby maintaining reliability while minimizing space consumption.
4Adaptability or versatility
If a vehicle-wide network is implemented, then communication capability is enhanced, but heat generation increases
Solution Approach 1:
The patent segments the communication network into multiple local wireless connections between RCUs and vehicle systems rather than implementing a single large centralized communication hub. This distributed wireless mesh network provides vehicle-wide communication capability while distributing heat generation across many small low-power nodes rather than concentrating it in one location.
Solution Approach 2:
The patent replaces traditional wired mechanical communication systems with wireless communication technology. This substitution eliminates the need for extensive physical wiring harnesses and associated heat-generating connectors and signal amplifiers, providing enhanced communication capability while reducing overall heat generation through the use of low-power wireless protocols.
