Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wind chimes that incorporate lighting features rely on conductive contact between resonant elements and strikers, requiring regular maintenance to ensure clean and corrosion-free contacts, and lack simultaneous sound-activated illumination responses.
Innovation Solution
Incorporation of sensors and processors that react to the sound produced by striker-to-resonant element contact, activating lighting elements nearly simultaneously with the sound, eliminating the need for conductive contacts and allowing the use of non-conductive materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductive contact between resonant elements and strikers is used to activate lighting, then the lighting can be activated by sound, but the conductive contacts require regular maintenance to ensure clean and corrosion-free contacts
Solution Approach 1:
The patent replaces the mechanical conductive contact system with an acoustic sensor-based system. Instead of relying on physical contact between striker and resonant element to activate lighting, the system uses acoustic sensors to detect sound waves generated by the strike, converting mechanical contact into acoustic detection. This eliminates the need for conductive contacts and their associated maintenance requirements.
Solution Approach 2:
The patent introduces acoustic sensors as an intermediary between the sound-producing mechanism and the lighting activation. The acoustic sensors act as a mediator that detects sound waves from the striker-resonant element interaction and translates them into electrical signals to control the lighting, eliminating the need for direct conductive contact between the mechanical components.
2Reliability
If conductive contact systems are used for sound-activated lighting, then the lighting responds to sound, but the system complexity increases due to requirements for clean and corrosion-free contacts
Solution Approach 1:
The patent replaces the complex mechanical conductive contact system with a simpler acoustic detection system. Instead of requiring precise, clean, corrosion-free conductive contacts between multiple components, the system uses acoustic sensors to detect sound waves, significantly reducing the complexity of the electrical and mechanical interface requirements.
Solution Approach 2:
The patent extracts the conductive contact requirement from the system by using acoustic sensors to detect sound waves generated by the mechanical interaction. This separation allows the mechanical components (striker and resonant element) to function independently of complex conductive pathways, simplifying the overall system design.
3Speed
If traditional lighting activation methods are used in wind chimes, then the lighting can be activated, but the illumination does not appear simultaneous with the sound production
Solution Approach 1:
The acoustic sensors are positioned to detect sound waves as they are generated by the striker's contact with resonant elements. By capturing the acoustic signal at the moment of impact and immediately processing it to activate the lighting, the system eliminates time delay and achieves simultaneous appearance of sound and illumination.
Solution Approach 2:
The system uses acoustic feedback from the sound waves generated by the strike to immediately trigger the lighting activation. The acoustic sensors detect the sound waves produced by the mechanical interaction and feed this information back to the control circuit, which then activates the lighting in real-time, creating a simultaneous effect.

Data Source
AI summary
A wind-driven sound and light device has at least one resonant element, a striker configured to strike the at least one resonant element in response to wind, thereby producing a ringing event. A lighting element comprising an illuminator is associated with each resonant element. The device also has a power source, a ring event sensor, and an illumination processing system. The ring event sensor produces a data signal in response to a ring effect The illumination processing system is configured to receive the data signal from the ring event sensor and, in response to the data signal, cause the circuit arrangement to activate the illuminator of at least one of the at least one lighting element by connecting it to the power source.
