Solution Overview
Problem
Existing electric guitars require significant effort and tools to replace pickups, limiting the ability to quickly switch between different tonalities and sounds.
Innovation Solution
An electric guitar design featuring continuous recesses on the guitar body for tool-less pickup exchange, with a touch screen for infinite switching of pickups and an electronic circuit allowing for seamless integration and adjustment of pickup elements, enabling rapid and easy replacement of pickups without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional pickup installation methods are used, then secure electrical connection is achieved, but pickup replacement requires tools and significant time
Solution Approach 1:
The pickup system is divided into modular components: a pickup element with contact elements and a separate mounting frame with recesses. This segmentation allows the pickup element to be quickly inserted and removed from the mounting frame without tools, enabling rapid replacement while maintaining secure electrical connections through the contact elements engaging with the mounting frame.
Solution Approach 2:
The traditional mechanical screw-based or soldered pickup installation is replaced with a simplified mechanical insertion system. The pickup element features contact elements that directly engage with corresponding recesses in the mounting frame, eliminating the need for tools and complex assembly procedures while ensuring reliable electrical connection.
2Adaptability or versatility
If multiple pickups are installed for tonality switching, then sound versatility is improved, but device complexity increases
Solution Approach 1:
The mounting frame is designed as a universal platform with standardized recesses that can accommodate different pickup elements. The consistent interface design across multiple mounting frames allows musicians to switch between different pickups for various tonalities while using the same installation mechanism, reducing overall system complexity despite having multiple pickups.
Solution Approach 2:
Instead of integrating multiple pickups into a single complex assembly, the invention allows individual pickups to remain separate and interchangeable. The mounting frame provides the standardized interface, and multiple identical mounting frames can be installed at different positions on the guitar body, each accepting different pickup elements for tonality switching.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and effortless pickup replacement within 3 to 5 seconds, allowing for continuous and variable tonality switching, enhancing musical versatility and convenience.
Implementation Method 1
Each pickup of a so-called pickup consists of an electric coil of several thousand turns of varnished copper wire around a magnetic core
Implementation Method 2
The vibration of the string near one end of the coil induces electric currents in the coil due to the magnetic flux altered by the vibration of the string
Implementation Method 3
The ferromagnetic strings must not be attracted by the magnet to such an extent that their vibration is significantly affected

AI summary
The electric guitar contains at least one pickup in a recess on the guitar body. This pickup can be installed in a mounting frame and has electrical contact points which lead via a cable to the output port on the guitar body. The pickup has a fixing plate on its rear side, which is screwed onto the height adjuster of the pickup via a threaded bush at a variable distance from the base plate of the pickup. It contains spring-loaded pins which are electrically connected to the coils of the pickup. The fixing plate can be inserted without tools from the rear of the guitar body into a recess in the pickup frame and removed again from the pickup frame without tools. When the pickup is inserted, the pins on the fixing plate are connected to the electrical contact points on the mounting frame and the fixing plate is held in place on the mounting frame by means of permanent magnets.
