Rotating Frame for Compact Electric Guitar Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric stringed instruments face challenges in compactness during transportation and storage, handling difficulties due to detachable frames which can be misplaced or unexpectedly detached, and cumbersome preparation for play or packing.
Innovation Solution
A design where one of the pair of frames is rotatable and connected to the instrument main body, allowing the instrument to be folded compactly, preventing frame separation and interference with strings, and featuring a fixation mechanism to secure the frame in place during play, enabling easy handling and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the frames are detachably attached to the instrument main body, then the instrument can be carried in a compact manner and storage space can be reduced, but the frames may be misplaced or lost and may be unexpectedly detached during playing
Solution Approach 1:
The frame is designed to be movable relative to the instrument main body, allowing it to rotate between a deployed position during playing and a folded position for compact storage. This dynamic configuration enables the frame to adapt between two states: attached and functional during performance, and movable and compact during storage, resolving the contradiction between accessibility and compactness while maintaining reliability through controlled movement rather than complete detachment
2Volume of moving object
If the frames are detachably attached to the instrument main body, then the instrument can be made compact for storage, but preparation before playing or packing-up becomes troublesome
Solution Approach 1:
The frame's ability to rotate and move relative to the instrument main body allows for quick transitions between playing and storage configurations without requiring complex attachment or detachment procedures. The frame can be simply folded back during storage and rotated into position during playing, significantly reducing preparation time and improving operational convenience while maintaining compact storage capability
3Volume of moving object
If one of the pair of frames is made movable and rotatable, then the instrument can be folded compactly and handling is improved, but the frame may interfere with strings during rotation
Solution Approach 1:
The frame is designed to rotate in the width direction of the instrument main body, utilizing a different spatial dimension for movement. By rotating the frame back in the width direction rather than moving it in the length direction where strings are positioned, the invention achieves compact folding for storage while avoiding interference with the strings that extend along the length of the instrument

AI summary
An electric stringed instrument includes: an instrument main body which includes a front surface including a structure configured to hold a string; and a pair of frames which are connected to the instrument body. At least one of the pair of frames is a movable frame rotating toward the other one of the pair of frames with a longitudinal direction of the instrument main body serving as a rotating axis while going around a rear surface side of the instrumental body.
