Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vibration apparatus uses a complex structure with multiple separate components, then the manufacturing precision and reliability may be improved, but the device thickness and weight increase
Solution Approach 1:
The patent merges multiple separate components (vibration generating part, cover members, and connection layers) into an integrated structure where the connection layer simultaneously serves as both a structural connector and an electrical conductor, reducing the overall device thickness while maintaining manufacturing reliability through unified construction
Solution Approach 2:
The connection layer performs multiple functions simultaneously: it mechanically connects vibration parts, provides electrical conduction for driving signals, and structurally supports the overall assembly, thereby reducing the need for separate components and reducing device thickness
2Manufacturing precision
If a vibration apparatus uses traditional manufacturing processes with multiple assembly steps, then the manufacturing precision may be improved, but the manufacturing complexity and time increase
Solution Approach 1:
The patent combines multiple manufacturing steps into a unified process where connection layers are welded directly to vibration parts in a single operation, eliminating separate assembly steps for mechanical connection and electrical connection, thereby reducing manufacturing complexity while maintaining precision
Solution Approach 2:
The connection layers are pre-configured with both mechanical and electrical connection capabilities before final assembly, allowing for simplified welding processes that reduce manufacturing complexity while ensuring precise alignment and connection
3Strength
If a vibration apparatus uses traditional connection methods between vibration parts, then the structural strength may be improved, but the device weight and thickness increase
Solution Approach 1:
The patent changes the parameters of the connection layer by using welded connections with optimized material properties and thickness, achieving sufficient structural strength with a lighter and thinner connection layer compared to traditional mechanical fastening methods
Solution Approach 2:
The connection layer uses composite material structures that combine mechanical strength and electrical conductivity in a single lightweight component, replacing heavier traditional connection methods while maintaining structural integrity
4Length of moving object
If a vibration apparatus integrates signal cable and cover members, then the device thickness is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The signal cable and cover members are pre-integrated into a unified structure with predetermined positions and connections, allowing for simplified final assembly that reduces device thickness while maintaining manufacturing precision through pre-configured alignment features
