Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fast-charging battery system is implemented, then the energy replenishment speed is improved, but the device complexity increases
Solution Approach 1:
The battery system is divided into a main battery for primary propulsion and auxiliary batteries for secondary functions and emergency operations. This segmentation allows the main battery to be optimized for fast charging while auxiliary batteries handle less time-critical functions, reducing overall system complexity.
Solution Approach 2:
The energy management system dynamically allocates power between different battery modules based on real-time operational needs, charging status, and system priorities. This dynamic management optimizes charging efficiency while simplifying control through adaptive rather than static configurations.
2Loss of energy
If ducted fans are used instead of free-moving rotors, then thrust efficiency is improved, but the device complexity increases
Solution Approach 1:
The ducted fan design merges the propeller and duct into a single integrated component, where the duct structure serves both to contain the rotor and to provide aerodynamic benefits. This combination reduces the number of separate parts compared to a traditional rotor system with separate blade guards or shrouds.
Solution Approach 2:
The duct structure converts the harmful vortexes and tip losses that occur with free-moving rotors into beneficial aerodynamic features. The duct walls redirect airflow to reduce tip vortices, and the enclosed design prevents foreign object ingestion, transforming potential problems into performance advantages.
3Length of moving object
If an energy management system with dynamic allocation is implemented, then the range is improved, but the device complexity increases
Solution Approach 1:
The energy management system continuously monitors battery charge levels, power consumption rates, and operational status of various subsystems, using this feedback to dynamically adjust power allocation. This feedback loop enables extended range through optimized energy usage while keeping control complexity manageable through automated rather than manual management.
Solution Approach 2:
The energy management system operates autonomously, automatically allocating power between propulsion, auxiliary systems, and battery charging without requiring pilot intervention. This self-service capability extends range through optimal energy management while reducing the complexity of pilot workload and control interfaces.
4Area of moving object
If selectively bendable wings are added, then the effective wing surface is improved, but the device complexity increases
Solution Approach 1:
The wings incorporate selective bendability that allows them to change curvature and effective surface area in response to flight conditions. During vertical takeoff and landing, the wings maintain a compact configuration, while during horizontal flight, they extend and bend to increase effective wing area for improved aerodynamic efficiency.
Solution Approach 2:
The bendable wing structure serves multiple functions: it provides structural support during vertical operations, generates aerodynamic lift during horizontal flight, and can be configured to reduce drag in transition phases. This multi-functionality justifies the added structural complexity by eliminating the need for separate deployable wing surfaces.
