Cellular Phone Control for Guitar Effector Patch Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing guitar effector loop systems are inconvenient for players to confirm and select the configuration of patches, as they require manual switching and lack a user-friendly method to manage multiple combinations of effectors.
Innovation Solution
A cellular phone-based apparatus that controls the guitar effector loop, featuring a patch screen display unit, bank screen display unit, and control unit to easily select and set combinations of effectors, allowing players to visualize and manage patches through a graphical interface on the phone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple foot switches are used to control different effector combinations, then various tone combinations can be obtained, but it becomes difficult to manipulate the foot switches during performance to obtain the necessary tone
Solution Approach 1:
The patent introduces a control device as an intermediary between the player and the multiple foot switches. This control device provides a user-friendly interface (display unit and input unit) that simplifies the selection of effector combinations, eliminating the need for players to manually manipulate multiple foot switches during performance while still enabling access to various tone combinations.
Solution Approach 2:
The patent segments the control function by separating the selection interface from the effector control mechanism. The control device with display and input units handles the complex selection logic, while the foot switches remain as simple activation mechanisms. This segmentation allows players to easily select desired effector combinations through the control device without needing to understand or remember the complex switch combinations.
2Adaptability or versatility
If a guitar effector loop with multiple switches is used to set separate effector combinations, then patches can be stored and selected, but the player must push each switch in the selected patch to confirm the configuration
Solution Approach 1:
The control device creates a visual copy or representation of the effector combinations on its display unit. Instead of requiring players to physically test each switch combination to confirm the patch configuration, the display unit shows the configured patches, allowing players to quickly identify and select the desired patch without time-consuming manual verification.
Solution Approach 2:
The control device provides visual feedback by displaying the current patch configuration and available patches. This feedback mechanism allows players to immediately see which effector combinations are stored and currently active, eliminating the need to manually test each combination and significantly reducing the time required to confirm and select patch configurations.
3Ease of operation
If manual switching of effectors is required during performance, then direct control is achieved, but the player cannot use hands due to guitar playing
Solution Approach 1:
The control device with display and input units serves as a self-service interface that manages the complex logic of effector selection automatically. Players simply interact with the intuitive control interface, and the system handles the complexity of determining which effectors to activate based on the selected patch, providing hands-free operation during performance while managing the underlying system complexity.

AI summary
Provided is an apparatus installed in a cellular phone (700) to control a guitar effector loop. The apparatus includes a patch screen display unit for displaying a patch, which is constituted by combinations of the plurality of foot switches (600) and the compactors (500) set to the respective foot switches (600), on a patch screen (710) of the cellular phone (700), a bank screen display unit for display a bank constituted by the plurality of patches on a bank screen (720) of the cellular phone (700), and a control unit performing a control so that the patch screen (710) corresponding to a selected patch is displayed by the patch screen display unit when one patch is selected from the plurality of patches displayed on the back screen (720).
