Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Avalanche transceivers currently face challenges in assisting users to efficiently locate buried transceivers due to stress-inducing display observations and audio signals, which complicate the search process.
Innovation Solution
The integration of a control device in avalanche transceivers that outputs voice messages based on specific search events, adjusting the search strategy and providing clear instructions to the user, such as changing search directions or patterns, to simplify and expedite the location of the buried transceiver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If display observations and audio signals are used to guide the search, then the user receives directional information, but the search process becomes complicated and stressful
Solution Approach 1:
The patent replaces the mechanical/visual display system with an acoustic voice message system. Instead of requiring the user to visually interpret display arrows and audio signal volume changes, the system uses voice messages to directly communicate search status and directional guidance, substituting complex visual-audio mechanical interpretation with natural language acoustic communication.
Solution Approach 2:
The control device acts as an intermediary between the receiving unit (which detects signal strength and direction) and the user. It processes the raw signal data and translates it into comprehensible voice messages, mediating the information flow and presenting it in a user-friendly format that reduces cognitive load and stress.
2Reliability
If the user must observe display indications and monitor audio signals, then directional guidance is provided, but the user experiences significant stress and difficulty
Solution Approach 1:
The system performs self-service by automatically monitoring signal strength, calculating direction, and generating appropriate voice messages without requiring the user to perform these cognitive tasks. The transceiver system serves itself by autonomously processing search information and presenting it in an easily consumable voice format, freeing the user from stressful monitoring tasks.
Solution Approach 2:
The system implements feedback by continuously monitoring the received signal characteristics and immediately responding with voice messages that reflect the current search status. This real-time feedback loop provides the user with up-to-date directional information in a stress-reducing format, maintaining reliability while reducing harmful stress effects.
3Ease of operation
If voice messages are output based on search events, then search guidance is simplified, but the device complexity increases
Solution Approach 1:
The control device is designed with multi-functionality, serving both as the signal processing unit and the voice message generation system. By integrating these functions into a single control device rather than separate components, the patent achieves simplified user guidance while managing device complexity through functional integration.

AI summary
The invention relates to an avalanche transceiver, having a transmitting unit for transmitting at least one transmit signal, a receiving unit for receiving at least one transmit signal from at least one further avalanche transceiver, and a control device for controlling at least one loudspeaker. The control device is designed to control the at least one loudspeaker to output at least one voice message on the basis of at least one event. The at least one event is associated with a search for the at least one further avalanche transceiver. The invention further relates to a method for operating such an avalanche transceiver.
