Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mounting methods are used to connect the electric accessory to the mirror adjustment mechanism, then the electrical connection can be established, but the assembly becomes complex and prone to errors
Solution Approach 1:
The electrical connection system is segmented into separate prong-shaped conductive elements that can be independently positioned and connected to the electric accessory, rather than using a complex integrated wiring system. This segmentation simplifies the overall assembly while maintaining reliable electrical connections.
Solution Approach 2:
The prong-shaped conductive elements serve as intermediary components between the mirror adjustment mechanism and the electric accessory. These prongs provide a simple mechanical and electrical interface that eliminates the need for complex mounting brackets, screws, and wiring harnesses, thereby reducing assembly complexity while ensuring reliable connection.
2Reliability
If traditional mounting methods are used for the electric accessory, then the electrical connection can be established, but the manufacturing cost increases
Solution Approach 1:
The prong-shaped conductive elements are designed as simple, inexpensive components that can be easily manufactured and replaced if needed. Rather than using expensive complex mounting assemblies with multiple parts, the invention employs simple prongs that provide reliable electrical connection at minimal manufacturing cost.
Solution Approach 2:
The invention extracts the essential function of electrical connection from the complex mounting system and implements it through separate, simple prong-shaped conductive elements. This extraction allows the mounting structure to be simplified while maintaining the electrical connection function, thereby reducing manufacturing costs.
3Reliability
If rigid conductive elements are used, then reliable electrical connection is achieved, but the elements cannot follow the adjusting movements of the mirror
Solution Approach 1:
The conductive elements are designed with dynamic characteristics, allowing them to flex and move as the mirror adjusts its position. This dynamic design enables the elements to maintain reliable electrical connection while adapting to the mirror's adjusting movements, combining both reliability and adaptability.
Solution Approach 2:
The physical parameters of the conductive elements (such as flexibility, length, and positioning) are optimized to allow them to follow the mirror's adjusting movements while maintaining sufficient stiffness for reliable electrical connection. This parameter optimization resolves the contradiction between rigidity and adaptability.
