Programmable Horn Sound Regulator for Noise Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle horns are difficult to manage, often producing undesired loud and strident sounds that can cause embarrassment, health issues, and social conflicts, particularly in situations requiring alerting pedestrians in shared areas.
Innovation Solution
A sound measuring and regulating device that allows programmable control of horn sounds through a push button panel or remote control, enabling users to select specific acoustic signals for different situations without altering the horn's original mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the horn uses a basic operating mechanism with limited controllability, then the horn structure remains simple, but the horn emits shrill sounds causing negative reactions and health issues
Solution Approach 1:
The horn system is segmented into multiple independent sound emission modes (first acoustic signal and second acoustic signal), allowing selective activation based on situation. The control unit divides the horn's functionality into distinct operable states, enabling the driver to choose appropriate sound levels for different contexts, thereby reducing unnecessary noise pollution while maintaining operational simplicity.
2Reliability
If the horn emits strident sounds to alert pedestrians, then the alerting effectiveness is improved, but negative social interactions and conflicts increase
Solution Approach 1:
The horn system dynamically adapts its acoustic output based on the situation. The control unit enables switching between a first acoustic signal (lower intensity, shorter duration) and a second acoustic signal (higher intensity, longer duration) depending on the driver's needs. This dynamic control allows effective pedestrian alerting while giving the driver the ability to moderate sound intensity, thereby reducing unnecessary social conflicts.
3Device complexity
If the horn switch is difficult to manage, then the horn structure remains simple, but undesired sounds are emitted creating embarrassing situations
Solution Approach 1:
The horn switch is segmented into multiple independent buttons (first button and second button), each controlling a specific acoustic signal. This segmentation allows the driver to deliberately select the appropriate sound level for each situation, preventing accidental activation of strident sounds while maintaining overall system simplicity. Each button provides clear, distinct control for its associated acoustic mode.
4Reliability
If the horn emits loud sounds to ensure safety, then pedestrian awareness is improved, but noise pollution and health issues increase
Solution Approach 1:
The horn system provides dynamic control over acoustic intensity and duration. The control unit allows selection between a first acoustic signal (lower intensity, shorter duration for routine situations) and a second acoustic signal (higher intensity, longer duration for critical situations). This dynamic capability ensures pedestrian awareness is maintained while minimizing unnecessary noise pollution and health impacts from excessive horn usage.

Data Source
AI summary
A sound measuring and regulating device for a horn comprises a push button panel (1) or a remote control (10) with push button switches, whereby activating one of the switches sends a signal to be evaluated by a main control module (2) that is connected to a relay (4), which activates an automotive horn (5), processing a specific, pre-programmed sound for that contact. Each push button corresponds to a programmed sound, fulfilling the expectations of the user. The aim of the present invention is to regulate and dispense these sounds, thereby creating a healthier environment for all without interfering with the original setup of the steering wheel's panel (3) which continues to activate the factory's original horn.
