Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a transformer is used to convert utility power to charge the battery or power the notebook computer, then the power conversion function is achieved, but the weight and portability are deteriorated due to the need to carry the transformer
Solution Approach 1:
The patent extracts the power conversion function from the portable transformer and relocates it to a fixed wall-mounted power supply device. The notebook computer and battery remain portable, but the heavy transformer is left behind at the charging location, allowing users to travel without carrying it.
Solution Approach 2:
The invention transitions the power conversion system from a portable dimension (handheld transformer) to a fixed installation dimension (wall-mounted device). This spatial repositioning separates the heavy power conversion equipment from the portable computer, resolving the weight burden while maintaining power conversion capability.
2Reliability
If a transformer is carried to ensure continuous operation of the notebook computer, then the power supply reliability is improved, but the convenience and ease of operation are worsened due to the burden of carrying it
Solution Approach 1:
The power conversion function is extracted from the portable equipment and placed in a fixed wall-mounted unit. Users only need to connect the battery to the wall-mounted device for charging, eliminating the need to carry the transformer while ensuring continuous operation capability.
Solution Approach 2:
The wall-mounted power supply device acts as an intermediary between the utility power source and the notebook computer battery. It provides the power conversion function at a fixed location, allowing the battery to be recharged without carrying the transformer, thus improving ease of operation.
3Ease of operation
If a wall-mounted power supply device is used to convert utility power to direct current power, then the portability and ease of operation are improved by eliminating the need to carry a transformer, but the device complexity increases due to the power conversion components
Solution Approach 1:
The complex power conversion system is extracted from the portable domain and placed in a fixed wall-mounted installation. This allows the complexity to be concentrated in a stationary device that remains at the charging location, while the portable components (notebook computer and battery) remain simple and easy to carry.
Solution Approach 2:
The power supply system is segmented into two parts: a fixed wall-mounted power conversion device and a portable battery unit. The complex power conversion components are isolated in the stationary device, while the portable portion remains simple, resolving the contradiction between portability and device complexity.
