Multi-Conductor Guitar Cable and Switching Device for Simultaneous Pickup Signal Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric guitars can only deliver a single mono sound signal to downstream devices, limiting the ability to capture and process multiple sound characteristics from multiple pickups, which are essential for stereo recording and advanced sound manipulation.
Innovation Solution
A switching device and multi-conductor cable system that allows simultaneous transmission of signals from individual pickups and their combinations to downstream devices, enabling multi-channel recording and processing, while maintaining backwards compatibility through a pickup buffer circuit and power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single mono plug is used for connection to downstream devices, then the device complexity is reduced and backwards compatibility is maintained, but the ability to deliver multiple simultaneous signals from multiple pickups is lost
Solution Approach 1:
The patent segments the single audio signal into multiple independent pickup signals by using a multi-conductor cable with separate conductors for each pickup (neck, bridge, middle). This allows each pickup to be transmitted as an independent channel to downstream devices, enabling simultaneous delivery of multiple signals while maintaining a relatively simple connection system.
Solution Approach 2:
The switching device is designed with multi-functionality to handle both traditional single-signal connections and new multi-signal configurations. It can process individual pickup signals, combined signals, and pass-through signals through a single interface, making the system adaptable to various connection scenarios without requiring multiple specialized connection systems.
2Loss of information
If multiple pickups are used on the guitar, then the sound quality and recording capability are improved, but the ability to deliver all pickup signals simultaneously to downstream devices is limited
Solution Approach 1:
The patent transitions from a single-dimensional mono signal transmission to a multi-dimensional multi-channel signal transmission system. By using a multi-conductor cable with multiple independent conductors, each pickup signal can be transmitted simultaneously on separate channels, preserving all sound information from multiple pickups without requiring complex matrix switching or signal mixing.
3Adaptability or versatility
If a breakout box is used to deliver individual pickup signals, then the signal transmission capability is improved, but the device complexity and cost increase
Solution Approach 1:
The patent merges the functions of multiple pickups, signal switching, and output routing into a single integrated switching device. This consolidates what would traditionally require separate breakout box equipment into one unit that handles all signal routing functions internally, reducing the need for external equipment while maintaining full signal routing flexibility.
4Productivity
If conventional single signal delivery is used, then the equipment cost is reduced, but the recording and sound manipulation capabilities are limited
Solution Approach 1:
The patent performs preliminary signal separation and organization by delivering individual pickup signals as separate channels before they reach the recording device. This preliminary action at the guitar interface allows downstream recording software to easily create multiple tracks and apply different processing to each pickup, significantly improving recording efficiency compared to capturing a single mixed signal.
Data Source
AI summary
A switching device receives an output cable from a guitar. The output cable has a plurality of conductors corresponding to each of the pickups on the guitar, typically 2 or 3. A passthrough signal based on manually switched pickup selection corresponds to a main guitar output. A pickup buffer circuit on the guitar isolates the signal conductors from the selected passthrough signal, and also switches the pickup buffer circuit on and off to allow for backwards compatibility. A multi-conductor cable and jack simultaneously transmits the plurality of signals to the switching device. The switching device receives the multi-conductor cable. A combination circuit in the switching device combines the signals from the pickups and also delivers the individual pickup signals to a respective output jack. Each output jack simultaneously delivers the respective pickup or combined signal to a mixer, amplifier or other signal processing device for recording and/or further processing.
