Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If adapters are designed with constant output power, then manufacturing and design are simplified, but adaptability to different power specifications deteriorates
Solution Approach 1:
The adapter is divided into two independent segments: a power core unit with constant output power and a converter with detachable input port. This segmentation allows the power core unit to maintain simplified manufacturing while the converter can be configured with different connection terminals to match various power specifications, thus resolving the contradiction between ease of manufacture and adaptability.
Solution Approach 2:
The converter is designed as a universal component that can interface with multiple types of power core units through detachable input ports with different connection terminals. This multi-functionality enables a single adapter design to support various power specifications (different voltages, currents, and connection types) without requiring separate manufacturing for each specification, thereby achieving both ease of manufacture and adaptability.
2Manufacturing precision
If adapters are designed for specific power specifications, then power delivery precision is improved, but device complexity increases due to multiple adapter variants
Solution Approach 1:
By segmenting the adapter into a standardized power core unit and a configurable converter, the patent eliminates the need for multiple complete adapter variants. Each converter can be precisely configured with specific connection terminals for different power specifications, while the power core unit remains standardized, thus reducing overall device complexity while maintaining power delivery precision.
Solution Approach 2:
The connection terminals in the input port are designed with local quality variations to match specific power specification requirements. Different terminals can be selectively activated or configured based on the required power delivery precision, allowing the adapter to maintain high manufacturing precision for power delivery without requiring complete redesign of the entire adapter for each specification.
3Adaptability or versatility
If adapters are replaced frequently to match different products, then product compatibility is improved, but resource waste increases
Solution Approach 1:
The converter is designed as a universal component that can work with multiple power core units and different product requirements through detachable input ports. This universality allows users to retain a single converter and simply change the power core unit or connection terminal configuration to match different products, achieving full product compatibility while eliminating the need to discard entire adapters, thus significantly reducing resource waste.
Solution Approach 2:
The detachable input port design enables selective replacement of only the necessary component (power core unit or terminal configuration) while retaining the converter housing and other components. This partial replacement approach allows users to recover and reuse the majority of the adapter components across different product configurations, minimizing resource waste while maintaining product compatibility.
