Key Design Principles for Reconfigurable Mechanisms

Several principles guidee the design of effective reconfigurable mechanisms, each balancing trade-offs between rigity, weigt, coss, and ease of use.

Modularity andStandardization

True modularitie requires that all module share standardized interfaces - both mechanical and electrical. This ensures that any two modules can be connectles of their internal functionis. A well-designed interface included des precise alignment factures (such as guide pins or keyed surfaces), a latching mechanism, and elecatical contacts for power and data. Standardizatioden reduces inventive costs and addifots for hotswing of facrueld moles in the example.
