Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the charging cable length is increased to provide high-power charging function, then the charging capability is improved, but the cable weight and management difficulty increase
Solution Approach 1:
The patent employs a dynamic cable management system with a retractable cable reel that can automatically extend and retract the charging cable based on usage needs. The cable reel is mounted on a movable support structure that can be positioned at different locations, allowing the cable length and management point to be dynamically adjusted. This resolves the contradiction by providing long cable length when needed while automatically retracting to minimize management difficulty when not in use.
Solution Approach 2:
The charging system is divided into separate functional modules: a cable reel unit, a movable support structure, and a control system. The cable reel can be independently positioned and controlled, allowing the cable management function to be separated from the fixed charging pile structure. This segmentation enables flexible cable length adjustment while maintaining ease of management through modular control.
2Length of moving object
If the charging cable length is increased, then the charging range is expanded, but the cable weight increases causing pressure and safety risks
Solution Approach 1:
The patent employs the spring balancer mechanism that generates an upward counterbalancing force equal to the cable weight. This counterweight mechanism compensates for the heavy cable weight, making the cable feel weightless during operation and reducing pressure on both the cable structure and handling components while maintaining the necessary cable length for expanded charging range.
Solution Approach 2:
The cable reel is mounted on a movable support structure that can be positioned at different locations along the charging pile. This dynamic positioning allows the cable to be deployed from the optimal location, reducing the actual cable length needed and thereby reducing the effective cable weight and pressure while still providing sufficient charging range.
3Device complexity
If a fixed cable support structure is used, then the structure is simple, but the charging range is limited
Solution Approach 1:
The patent replaces the fixed support structure with a movable support structure that can be positioned at different locations. The support structure includes a movable carriage or trolley that can travel along a guide rail or track system, allowing the cable reel to be dynamically repositioned to extend the charging range while maintaining relatively simple structural components.
Solution Approach 2:
The movable support structure serves multiple functions: it provides structural support for the cable reel, enables repositioning to extend charging range, and can be integrated with the spring balancer system for cable weight compensation. This multi-functionality increases adaptability and charging range without proportionally increasing device complexity.
