Cello Harness Peg Belt and Strap Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to allow cellists to play the cello while standing, walking, dancing, or rotating, due to limitations in physical mobility and ergonomic positioning, and existing strap harnesses damage acoustic instruments or do not accommodate the cello's size and shape.
Innovation Solution
A harness system comprising a peg belt, strap assembly, and neck connector that secures the cello to the player's body without drilling into the instrument, allowing for adjustable positioning of the cello's oblique, rotational, and height angles, and distributing the instrument's weight ergonomically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional endpin and seated playing position is used, then the cello can be stable and properly positioned according to ergonomic principles, but the player cannot stand, walk, dance, or rotate the torso while playing
Solution Approach 1:
The harness divides the support function into multiple segments: a first strap connecting the neck to the player's body, a second strap connecting the body to the player's body, and a third strap connecting the endpin to the player's body. This segmentation allows the weight distribution to be spread across multiple attachment points, enabling mobility while maintaining ergonomic positioning.
Solution Approach 2:
The invention transitions from a two-dimensional seated positioning system to a three-dimensional spatial support system. The harness allows the cello to be positioned in multiple spatial configurations (standing, sitting, rotating) while maintaining proper ergonomic angles through adjustable strap lengths and attachment points distributed across the player's body in three dimensions.
2Ease of operation
If existing strap harnesses are used to hold the cello while standing, then the player can stand and move, but the harness damages acoustic instruments or does not accommodate the cello's size and shape
Solution Approach 1:
The harness is designed with specific attachment points tailored to the cello's unique geometry: the first strap connects to the neck, the second strap connects to the body, and the third strap connects to the endpin. This localized attachment strategy distributes stress across robust structural elements of the cello rather than concentrating force on vulnerable areas, preventing damage while accommodating the instrument's specific size and shape.
Solution Approach 2:
The harness employs adjustable strap lengths and connection points that can be dynamically configured to match different cello sizes and player anatomies. This dynamic adaptability allows the same harness design to work with various acoustic instruments without modification, preventing damage through proper force distribution while maintaining standing and moving capability.
3Adaptability or versatility
If the cello is held between the knees while seated, then the instrument is stable, but the player cannot communicate effectively with other performers or engage with the audience
Solution Approach 1:
The harness uses the player's body as a counterweight system, with straps distributing the cello's weight across the shoulders, chest, and hips. This counterbalancing approach frees the player from being anchored to a seated position, allowing full body movement, rotation, and engagement with the audience while maintaining instrument stability through the distributed weight support system.

AI summary
A harness for suspending a large stringed instrument on the player. A peg belt wraps around and secures the harness to the peg box. A strap assembly stretches diagonally across the player's back from the peg belt to the endpin or anchor. The strap assembly has a central sash with a bottom extension and a top extension. Optional detachable sash cushions attach to the inner surface of the sash. An eyelet in the bottom extension attaches at the endpin. A neck connector extends from the outer surface of the sash near the top end of the sash. The free end of the neck connector loops between the neck/fingerboard and instrument body and detachably attaches to the free end of the top extension. The peg belt detachably attaches to the neck connector. An optional chest cushion hangs from the instrument where the neck/fingerboard attach to the instrument body.
