Solution Overview
Problem
Hearing devices with removable receivers experience interference from electrical and magnetic radiation, which impairs wireless signal reception and increases feedback risks, particularly with telephone loop operation, due to the need for multiple cables.
Innovation Solution
A hearing apparatus design that combines the sheath cable and electronic identification element into a single-pole connection, allowing a smaller connector and reducing overall size, using a three-pole plug for conventional control, with options for grounding high-frequency interference and utilizing a multiplexer for identification and volume control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a separate sheath cable is added to shield electromagnetic radiation, then shielding effectiveness is improved, but the number of cables and connector size increase
Solution Approach 1:
The patent combines the sheath cable and identification element into a single integrated connection structure. The sheath cable serves dual purposes: providing electromagnetic shielding and carrying identification information for the receiver type. This merging eliminates the need for separate shielding cables and reduces connector complexity while maintaining effective shielding against electromagnetic radiation.
Solution Approach 2:
The sheath cable is designed to perform multiple functions simultaneously: it provides electromagnetic shielding, transmits identification signals for receiver recognition, and maintains electrical connections. This multi-functionality reduces the overall number of components needed while achieving both shielding effectiveness and device identification capabilities.
2Adaptability or versatility
If multiple cables are used for signal transmission and identification, then functionality is improved, but cable thickness and connector size increase
Solution Approach 1:
The patent integrates the identification element directly into the existing signal cable structure. The identification element is embedded within the cable assembly, allowing identification signals to be transmitted through the same physical medium used for audio signal transmission. This eliminates the need for additional dedicated identification cables and reduces overall cable thickness.
Solution Approach 2:
The identification element is nested within the cable structure itself, utilizing the existing cable pathways and connectors. This nesting approach allows multiple functions (signal transmission and identification) to coexist within a single cable assembly of minimal thickness, avoiding the need for larger connectors or thicker cables.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design effectively shields interfering fields, reduces cable thickness, and maintains small connectors, enhancing wireless signal reception and reducing feedback by integrating identification and shielding functions within a single connection.
Implementation Method 1
The signal cables to the loudspeaker and the loudspeaker itself are known to radiate electrical and magnetic energy. This energy and/or the corresponding fields interfere with the operation of the hearing device. A simple solution to this radiation problem consists in shielding the interfering fields by means of a sheath cable.

AI summary
A hearing apparatus with an external receiver is to be made even smaller. Provision is accordingly made for a hearing apparatus with a housing and a receiver device that is removably electrically coupled to the housing, said receiver device having an electronic identification element and having a receiver that is connected to an electrical cable with a sheath cable, with the sheath cable and the electronic identification element being conducted into the housing via a common single-pole connection. As a result of the multiple usage of the single-pole connection for shielding and identification, the female connector of the hearing device and the plug of the receiver device can be made smaller.
