Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solutions for communicating with remote devices in harsh environments, such as NEMA4 or IP66 compliant enclosures, face challenges including high costs, quality issues, and inefficiency in transmitting complex information, especially with buttons that degrade over time, and wireless solutions that deplete battery life or pose cybersecurity risks.
Innovation Solution
An acoustic interface that uses tone-based communication between a remote programming device and an industrial process device, allowing for efficient exchange of status information, configurations, and programming without the need for external buttons or wireless networks, utilizing a speaker and microphone to convert digital data into acoustic signals and vice versa, enhancing security and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external buttons are used for communication with sealed enclosures, then wireless access is avoided and sealing is maintained, but the buttons are prone to failure over time as sealing material ages and sunlight exposure increases
Solution Approach 1:
The patent replaces the mechanical button system with an acoustic communication system using a speaker and microphone. The speaker converts digital data to acoustic signals that can be heard outside the sealed enclosure, while the microphone captures external sounds to convert back to digital data. This eliminates the need for physical buttons that compromise the sealing, thereby maintaining both reliability and sealing integrity over time.
2Ease of operation
If WIFI or Bluetooth wireless interfaces are used to communicate with remote devices, then physical access and external buttons are eliminated, but battery life is greatly depleted
Solution Approach 1:
The patent substitutes energy-intensive electromagnetic wireless communication (WIFI/Bluetooth) with acoustic wave-based communication. The speaker generates sound waves that carry digital information outside the enclosure, and the microphone receives these acoustic signals. This mechanical/acoustic approach consumes minimal power compared to continuous wireless radio transmission, enabling battery-powered devices to maintain communication capability without rapid battery depletion.
3Device complexity
If simple button approaches are used for configuration, then device complexity is reduced, but the ability to transmit complex information such as strings and multiple parameters is insufficient
Solution Approach 1:
The patent transforms the communication interface from discrete button presses to continuous acoustic wave parameters. By varying frequency, amplitude, duration, and timing of acoustic signals, the system can encode and transmit complex information including strings, multiple parameters, and configuration data. This parameter-based acoustic encoding maintains interface simplicity while dramatically expanding information transmission capability beyond what simple buttons can achieve.

AI summary
Remote configuration of an industrial or remote telemetry device using sound. Acoustic energy directed from a remote programming device to a remote industrial or telemetry device has tones indicating a request to establish communication. By directing further acoustic energy from the remote programming device to the remote industrial or telemetry device, the remote programming device requests information relating to a current configuration of the remote industrial or telemetry device. The remote industrial or telemetry device processes the tones to identify the request and replies with acoustic energy that has associated tones indicating the information relating to the current configuration of the remote industrial or telemetry device.
