Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If large volume assemblies are used, then structural strength is improved, but overall device volume increases and connection stability deteriorates
Solution Approach 1:
The device is divided into separate assemblies (loudspeaker assembly, sound-pickup assembly, connection assembly) that can be independently manufactured and connected. This allows each component to be optimized for its specific function while maintaining overall structural strength without requiring the entire device to be large in volume.
Solution Approach 2:
The connection assembly incorporates an elastic member that acts as a flexible connection element between assemblies. This elastic member provides structural strength and connection stability while occupying minimal volume, replacing the need for large rigid connection structures.
2Strength
If large volume assemblies are used, then structural strength is improved, but connection stability deteriorates
Solution Approach 1:
The elastic member in the connection assembly provides flexible yet stable connections between assemblies. Its elastic properties allow it to absorb mechanical stresses and vibrations, maintaining connection stability while providing sufficient structural strength to hold assemblies together securely.
Solution Approach 2:
The elastic modulus of the elastic member is specifically controlled within the range of 70-90 GPa to optimize both connection stability and structural strength. This parameter optimization ensures the connection is stable enough to prevent detachment while maintaining the necessary strength to support the assemblies.
3Strength
If rigid connections are used, then structural strength is improved, but vibration transmission increases and sound quality deteriorates
Solution Approach 1:
The elastic member serves as a vibration isolation element between the loudspeaker assembly and sound-pickup assembly. Its elastic properties allow it to dampen and absorb vibrations generated by the loudspeaker, preventing excessive vibration transmission to the sound-pickup assembly while maintaining structural strength for secure connection.
Solution Approach 2:
The elastic member acts as an intermediary element between the loudspeaker assembly and sound-pickup assembly. It mediates the mechanical connection by providing both structural support and vibration damping, reducing the harmful vibration transmission that would occur with direct rigid connections.
4Device complexity
If assembly connections are simplified, then device complexity is reduced, but connection stability deteriorates
Solution Approach 1:
The connection assembly integrates multiple functions into a single component: mechanical connection, vibration isolation, and structural support are all provided by the elastic member. This merging of functions simplifies the overall assembly process while maintaining connection stability, as the elastic member is designed to perform multiple roles simultaneously.
