Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current material computation systems are used, then computational functions can be achieved, but the ability to self-learn and adapt autonomously is lost
Solution Approach 1:
The mechanical circuit performs self-learning through autonomous weight updates based on environmental inputs. The system automatically adjusts its internal state (spring stiffness) without external control, enabling it to adapt to changing environments and uncover hidden patterns in data streams.
Solution Approach 2:
The patent implements dynamic adaptability through adaptive directed springs that continuously modify their stiffness properties in response to environmental inputs. This dynamic adjustment allows the mechanical system to transition between different computational states and adapt its behavior autonomously.
2Adaptability or versatility
If adaptive materials are used to solve optimization problems, then computational functionality is achieved, but the ability to continually respond to changing environments without external reset is limited
Solution Approach 1:
The mechanical circuit incorporates feedback mechanisms where environmental inputs continuously influence the internal state of the system. The spring stiffness adjustments are based on ongoing environmental conditions, allowing the system to maintain adaptive responses without external intervention or reset.
Solution Approach 2:
The system maintains continuous computational action through persistent environmental interaction. The mechanical circuit processes environmental inputs continuously, updating its internal state without interruption, thereby achieving unlimited operational duration in changing environments.
3Use of energy by moving object
If purely mechanical forms of adaptivity are implemented, then energy efficiency is improved, but the complexity of embedding sensing and actuation increases
Solution Approach 1:
The patent replaces electronic sensing and actuation systems with purely mechanical equivalents. The adaptive directed springs serve as both sensors and actuators, detecting environmental forces and mechanically adjusting their stiffness in response, thereby eliminating the need for complex electronic control systems while maintaining energy efficiency.
