Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If stackable storage containers are designed for portable transport, then mobility and convenience are improved, but integrated power supply capability deteriorates
Solution Approach 1:
The patent combines a power outlet box with a rotatable drum mechanism for cord management directly into the stackable storage container system. This integration merges the power supply function with the portable storage function, allowing the container to simultaneously provide both mobility and electrical power capability through a unified design structure.
2Adaptability or versatility
If a power outlet box is integrated into the stackable container system, then power supply functionality is improved, but device complexity increases
Solution Approach 1:
The outlet box is designed to serve multiple functions: it provides electrical power outlets, incorporates a rotatable drum for cord winding and storage, and maintains the stackable container interface for integration with other containers. This multi-functionality reduces the need for separate components, thereby managing complexity while enhancing power supply capability.
Solution Approach 2:
The rotatable drum mechanism for cord management is nested within the outlet box housing. The power cord is wound around the drum, which rotates to extend or retract the cord as needed. This nested design consolidates the cord management system within the existing outlet box structure, minimizing additional complexity.
3Ease of operation
If cord management features are added to the outlet box, then ease of operation is improved, but manufacturing complexity increases
Solution Approach 1:
The rotatable drum mechanism is designed to be manually operated by the user to wind and store the power cord. The spring-loaded latch automatically secures the drum in position during rotation, providing a self-regulating mechanism that requires minimal manufacturing complexity while delivering convenient cord management operation.

AI summary
A power outlet box is disclosed. The power outlet box includes a housing having a drum disposed therein, the drum being rotatable relative to the housing. The power outlet box includes a power cord windable about the drum, the power cord being extendable or retractable through an opening in the housing based on a direction of rotation of the drum. The power outlet box includes at least one power outlet externally fixed on the housing and electrically coupled to the power cord. The at least one power outlet remains electrically connected to the drum as the drum rotates relative to the housing.
