Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed configuration of exoskeleton robot is used, then the structure is simple, but it cannot accommodate users with varying hand sizes
Solution Approach 1:
The exoskeleton robot is divided into multiple detachable modules: a palm module and multiple finger joint modules. Each finger joint module can be independently attached to or removed from the palm module, allowing the configuration to be customized according to different hand sizes and training requirements. This segmentation enables adaptability without requiring a completely different device for each user.
Solution Approach 2:
The exoskeleton robot transitions from a fixed configuration to a dynamic, reconfigurable system. The detachable connections between modules allow the structure to be dynamically adjusted based on user needs. Users can attach or detach finger joint modules to match their hand size and training objectives, making the device adaptable while maintaining relative structural simplicity.
2Adaptability or versatility
If multiple fixed types of exoskeleton robots are provided for different applications, then each application gets appropriate training, but the device complexity and inventory requirements increase
Solution Approach 1:
A single base exoskeleton robot design serves multiple applications and user types through its modular architecture. The palm module can be combined with different numbers and types of finger joint modules to create configurations suitable for various training applications. This universality eliminates the need to maintain separate inventories for different robot types while still providing application-specific training capabilities.
Solution Approach 2:
By segmenting the exoskeleton into standardized modules (palm module and finger joint modules), the system allows flexible reconfiguration for different applications. Instead of maintaining multiple fixed robot types, organizations need only maintain one base design with varying module combinations, simplifying inventory management and reducing overall system complexity.
3Adaptability or versatility
If detachable modules are used to customize configurations, then adaptability to different hand sizes is improved, but the assembly and disassembly time increases
Solution Approach 1:
The modules are designed with pre-configured connection interfaces and attachment mechanisms that prepare the system for quick assembly. The detachable connections are engineered to enable rapid attachment and detachment without requiring complex tools or procedures, minimizing the time loss while maintaining customization capability.
