Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed detection time is used for battery failsafe activation, then the system can quickly detect voltage drops, but the failsafe activates prematurely due to voltage fluctuations from high-power servo devices and battery internal resistance variations
Solution Approach 1:
The patent applies the dynamics principle by making the detection time configurable rather than fixed. The system allows operators to adjust the detection time parameter to match specific operational conditions, transforming a static system into a dynamic one that can adapt to different power consumption patterns and battery characteristics, thereby preventing premature failsafe activation while maintaining reliable voltage drop detection
Solution Approach 2:
The patent implements parameter changes by introducing configurable detection time and voltage threshold parameters. These parameters can be modified based on the specific battery type, servo device power consumption, and operational requirements, allowing the system to optimize between early detection and false activation prevention by changing the temporal and voltage parameters of the detection mechanism
2Measurement precision
If the battery failsafe function activates early due to voltage fluctuations, then voltage drop detection sensitivity is improved, but battery life is reduced due to unnecessary activation
Solution Approach 1:
The system uses dynamics by allowing the detection time parameter to be adjusted based on the specific operational context. By making the detection duration configurable, the system can differentiate between transient voltage drops (which should be ignored) and sustained voltage drops (which indicate real battery depletion), thereby maintaining high detection sensitivity without triggering unnecessary failsafe activations that would reduce battery life
Solution Approach 2:
The patent applies parameter changes by introducing configurable voltage threshold and detection time parameters. Operators can adjust these parameters to match the specific battery chemistry, capacity, and discharge characteristics, allowing the system to maintain precise voltage drop detection while avoiding premature failsafe activation caused by normal voltage fluctuations during high-power operation
3Ease of operation
If a fixed voltage threshold is used for failsafe activation, then the system is simple to operate, but it cannot adapt to different battery types and power consumption patterns
Solution Approach 1:
The patent implements universality by designing a configurable parameter system that can adapt to different battery types, capacities, and discharge characteristics. The object-side communication device can store and apply different detection time and voltage threshold parameters for different operational scenarios, making the system universally applicable across various battery and servo device combinations while maintaining ease of operation through automated parameter selection based on detected power consumption patterns
