Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a skeleton is provided in the sounding device, then the position of the voice coil can be adjusted and vibration symmetry improved, but the number of parts increases, manufacturing cost increases, assembly process becomes complex, and overall weight increases
Solution Approach 1:
The patent merges the voice coil assembly with the connection part by directly connecting the voice coil wire to the connection part, eliminating the skeleton. This integration reduces the number of parts while maintaining structural functionality for position adjustment and vibration symmetry.
Solution Approach 2:
The patent extracts and removes the skeleton component from the sounding device structure. By taking out the unnecessary skeleton, the design simplifies the assembly process and reduces part count while retaining essential functions through direct connections between remaining components.
2Strength
If a skeleton is provided in the sounding device, then structural support is provided, but the manufacturing cost increases and assembly process becomes more complex
Solution Approach 1:
The connection part assumes multiple functions including structural support and electrical connection by directly supporting the voice coil assembly. This merging eliminates the need for separate skeleton components, reducing manufacturing cost and simplifying production.
3Length of moving object
If a skeleton is provided in the sounding device, then position adjustment is enabled, but the overall weight of the sounding device increases
Solution Approach 1:
The patent removes the heavy skeleton component while maintaining position adjustment capability through the streamlined connection part design. This extraction reduces overall weight while preserving essential positioning functionality.
4Device complexity
If the voice coil is only connected by voice coil wire to the conductive element, then assembly is simple, but the connection stability is insufficient and separation may occur
Solution Approach 1:
The connection part integrates both electrical connection and mechanical support functions, creating a unified structure that simultaneously provides electrical connectivity and mechanical stability. This merging prevents separation while maintaining assembly simplicity.
Solution Approach 2:
The connection part acts as an intermediary component between the voice coil wire and the external circuit, providing a stable interface that enhances connection reliability while maintaining the simplicity of the overall assembly process.
