Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If inductive charging or cable routing is used for energy and data transmission between stack elements, then energy and data can be transmitted between containers, but the process becomes laborious and complex
Solution Approach 1:
The bus interfaces are automatically connected when stack elements are stacked together, enabling self-service energy and data transmission without manual intervention. The mechanical stacking action itself establishes the electrical connection through aligned contact surfaces, eliminating the need for separate charging or cable routing operations.
Solution Approach 2:
The invention merges the mechanical stacking function with the electrical connection function. The same physical act of stacking containers simultaneously achieves both mechanical support and electrical contact for energy/data transmission, combining two separate operations into one unified action.
2Use of energy by moving object
If manual cable routing or inductive charging is implemented, then energy transmission is possible, but the device complexity increases
Solution Approach 1:
The invention extracts the electrical connection function from complex cable routing systems and inductive charging mechanisms, simplifying it to direct contact through bus interfaces. This extraction removes unnecessary complexity while maintaining the essential energy and data transmission capabilities.
Solution Approach 2:
The invention replaces complex mechanical cable routing systems with a simpler contact-based bus interface system. Instead of requiring flexible cables and routing paths, the design uses rigid contact surfaces that automatically align when containers are stacked, substituting a complex mechanical system with a simpler one.
3Reliability
If individual connections are made for each stack element, then reliable energy and data transmission is achieved, but the time and effort required increases
Solution Approach 1:
The bus interfaces are pre-positioned and aligned on the stack elements during manufacturing, so that when the elements are stacked, the connections are automatically established without requiring on-site alignment or adjustment. This preliminary preparation eliminates time-consuming connection procedures while maintaining reliable electrical contact.
4Extent of automation
If bus interfaces are integrated into stack elements, then automated data and energy transmission is enabled, but the manufacturing complexity increases
Solution Approach 1:
The bus interface design uses universal contact surfaces and standardized protocols that can be implemented across different stack element types. This universality allows the same manufacturing processes and interface designs to be reused across multiple products, reducing overall manufacturing complexity despite the added automation capability.
