Solution Overview
Problem
Existing sound reproduction systems face challenges with complex and space-consuming mechanical and electrical connections between loudspeaker boxes and supporting structures, along with unreliable electrical connectors that tend to disconnect.
Innovation Solution
A sound reproduction system that includes a supporting structure with a distribution circuit and a loudspeaker box with a connection circuit, allowing for removable mechanical and electrical connections. The system features conductive tracks around a longitudinal axis, ensuring electrical continuity during rotation of the loudspeaker box, and deformable electrical connectors for reliable connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mechanical and electrical connections are used to connect loudspeaker boxes to supporting structures, then the connections are structurally complete, but the system becomes complex and occupies large space
Solution Approach 1:
The patent combines mechanical connection and electrical connection into a single integrated connector assembly. The connector includes both mechanical fastening elements (screws, clamps) and electrical contact elements (terminals, conductors) that work together as one unit, eliminating the need for separate mechanical and electrical connection components, thus reducing overall system complexity while maintaining connection reliability
Solution Approach 2:
The connector is designed as a multi-functional component that simultaneously provides mechanical support, electrical connection, and signal transmission. This universal connector can handle both power supply and audio signals through integrated terminals and conductors, reducing the number of separate connection devices needed and simplifying the overall connection structure
2Ease of manufacture
If traditional electrical connectors are used for connection, then the connection is established, but the connectors are unreliable and have a tendency to be disconnected
Solution Approach 1:
The mechanical fastening mechanism and electrical contact mechanism are merged into a single integrated connector. When the mechanical fastening elements (screws or clamps) secure the connection, they simultaneously apply pressure to ensure firm contact between electrical terminals and conductors, ensuring both mechanical stability and electrical reliability in one action
Solution Approach 2:
The connector design includes pre-compression features where the mechanical fastening elements apply continuous pressure to the electrical contacts before any disconnection can occur. This prior cushioning force ensures that the electrical connection remains firm and reliable, preventing loose connections or disconnections during operation
3Stability of the object's composition
If loudspeaker boxes are fixed to supporting structure, then stable connection is achieved, but replacement and adjustment become difficult
Solution Approach 1:
The connection system is segmented into removable connector components that can be easily detached and reattached. The loudspeaker box connects to the supporting structure through discrete connector assemblies rather than permanent fixed mounting, allowing individual boxes to be replaced or adjusted by simply detaching and reattaching the connector components without damaging the structure
Solution Approach 2:
The connector incorporates dynamic fastening mechanisms (such as threaded screws or spring-loaded clamps) that provide stable connection during operation but can be easily released when needed. This dynamic design allows the connection to transition between a secure fixed state during use and an easily removable state for maintenance or replacement
4Adaptability or versatility
If connectors are designed for full rotation capability, then rotational freedom is achieved, but the electrical connection becomes unreliable
Solution Approach 1:
The connector is segmented into a rotational mechanical interface and a fixed electrical interface. The mechanical portion allows full 360-degree rotation for positioning adjustments, while the electrical contacts are designed to maintain stable connection during rotation through features such as spring-loaded terminals or conductive materials that accommodate movement, thus separating the rotational function from the electrical connection function
