Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rear assembly of the auxiliary diaphragm in existing sounding devices is prone to accuracy deviations and gluing failures, which can lead to performance issues in portable electronic devices.
Innovation Solution
The sounding device incorporates a flange formed by bending the first connection portion of the holder away from the second connection portion, with the auxiliary diaphragm fixed to the flange, enhancing assembly accuracy and reducing gluing errors by embedding the flange in the second fixed portion and strategically fixing it along the vibrating direction of the diaphragm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the auxiliary diaphragm is glued to the first connection portion in the rear assembly, then the assembly process is simple, but assembly accuracy deviates and gluing failure risks increase
Solution Approach 1:
The flange acts as an intermediary component between the first connection portion and the auxiliary diaphragm. By bending the first connection portion to form a flange with a positioning hole, the design introduces a mediating structure that enables precise alignment through positioning pins, thereby resolving the contradiction between simple assembly and high assembly accuracy.
Solution Approach 2:
The first connection portion is preliminarily shaped into a flange structure with an integrated positioning hole before final assembly. This preliminary action of forming the flange with built-in positioning features eliminates the need for separate positioning components and ensures accurate positioning of the auxiliary diaphragm during assembly.
2Ease of operation
If the auxiliary diaphragm is glued to the first connection portion, then assembly is straightforward, but gluing failure hidden dangers increase
Solution Approach 1:
The flange serves as a reliable intermediary that provides a mechanical connection interface between the holder and auxiliary diaphragm. The positioning hole in the flange accommodates a positioning pin that creates a dependable mechanical constraint, reducing reliance on gluing alone and thereby improving overall connection reliability while maintaining assembly simplicity.
Solution Approach 2:
The design merges the connection function and positioning function into a single flange structure. By combining the bending of the first connection portion to form the flange with the integrated positioning hole, the invention creates a unified component that simultaneously provides both connection and precise positioning, eliminating the need for separate gluing and positioning operations.
