Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio arrangements for mobile units, such as bayonet type jacks and pogo pin interfaces, suffer from audio noise and mechanical issues that lead to poor audio quality and customer dissatisfaction.
Innovation Solution
An audio arrangement featuring a housing with integrated circuit contacts and a connector that establishes a direct electrical connection to the mobile unit's internal circuitry, eliminating external mechanical interconnects and noise, while allowing for rugged design and easy replacement of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bayonet type jack is used to couple the audio output device to the mobile unit, then the audio output device can be easily connected and disconnected, but audio noise such as static is introduced resulting in poor audio quality
Solution Approach 1:
The patent extracts the problematic mechanical rotation interface from the audio connection system. By using a fixed linear connector instead of a rotatable bayonet jack, the harmful rotational movement that causes contact variation and audio noise is eliminated, while maintaining the ability to easily connect and disconnect audio devices through a simple plug-and-play interface.
Solution Approach 2:
The patent replaces the mechanical rotation mechanism of the bayonet jack with a fixed linear electrical connector. This substitution eliminates the mechanical sources of audio noise (contact resistance changes, intermittent connections) while preserving the electrical connection function, thereby improving audio quality without sacrificing ease of operation.
2Strength
If a pogo pin type interface is used to eliminate rotation problems, then ruggedness is improved, but external mechanical interconnect points still cause audio issues
Solution Approach 1:
The patent removes the external mechanical interconnect point (pogo pin) from the system by integrating the electrical contacts directly into the mobile unit's housing. This elimination of the external interface point removes the source of audio noise while preserving the rugged, connection-free design for normal operation, with audio connectivity achieved through a simple jack interface.
3Adaptability or versatility
If external mechanical interconnects are used for audio output, then connectivity is enabled, but audio quality deteriorates due to noise and mechanical issues
Solution Approach 1:
The patent merges the audio output functionality directly into the mobile unit's housing structure. By integrating the electrical contacts and connector within the housing rather than using separate external mechanical interconnects, the design maintains connectivity versatility while eliminating the noise and mechanical issues associated with external interfaces.

AI summary
An arrangement includes (a) a housing situating an integrated circuit that includes first contacts and (b) a connector. The housing includes a window which exposes at least a portion of the first contacts. The connector includes second contacts disposed at a first end of the connector. The second contacts removably couple to the first contacts. A second end of the connector is coupled to an output device. The connector establishes an electrical connection for an exchange of multimedia data between the integrated circuit and the output device.
