Solution Overview

Problem

Existing learning aids for brass instruments do not effectively promote a technically correct wrist position, as they are separate devices that do not simulate the natural playing feel and do not improve wrist posture.

Innovation Solution

A learning aid that attaches directly to the leadpipe of a brass instrument, featuring a thumb guide that adjusts the thumb's position and tilt, ensuring correct wrist posture by specifying the spacing between the thumb and fingers and guiding the thumb into an ergonomically preferred position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a separate finger exercise device is used to improve fine motor skills, then finger dexterity is improved, but wrist posture is not corrected and the natural playing feel is not simulated

Engineering Contradiction:
Improvefinger motor skillsVSAvoidwrist position correction
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The invention combines the functions of finger exercise and wrist position guidance into a single integrated device that attaches directly to the brass instrument's leadpipe. The thumb guide element is merged with the finger exercise mechanism, allowing simultaneous correction of wrist posture and improvement of finger dexterity while maintaining the natural playing feel.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The thumb guide acts as an intermediary element between the player's thumb and the instrument's valve mechanism. It provides a physical reference that guides the thumb into the correct position, thereby indirectly correcting wrist posture while allowing natural finger movement for valve operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If a fixed thumb guide structure is used to enforce correct wrist position, then wrist posture is corrected, but the natural playing feel is lost

Engineering Contradiction:
Improvewrist position guidanceVSAvoidloss of natural playing feel
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The thumb guide is designed with dynamic characteristics that allow it to adapt to the player's natural movements. The guide provides directional guidance through its angled surface but does not rigidly constrain the thumb, allowing the player to maintain natural playing feel while receiving corrective guidance for proper wrist positioning.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The thumb guide's angled surface changes the spatial parameters of thumb placement, guiding it to the correct position and angle. By modifying the geometric parameters of the guide surface, the device provides wrist position correction without imposing rigid constraints that would eliminate the natural playing feel.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If the learning aid is made adjustable for different hand sizes, then adaptability to different musicians is improved, but device complexity increases

Engineering Contradiction:
Improvehand size accommodationVSAvoidadjustment mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The learning aid is designed as a segmented device with modular components that can be adjusted independently. The thumb guide element can be positioned at different locations along the leadpipe attachment, allowing adaptation to different hand sizes without requiring complex adjustment mechanisms. Each segment maintains its functional integrity while providing adaptability.

Inventive Principle:
Principle #1Segmentation

AI summary

A learning aid (1) for brass instruments is described to promote a technically correct fingering and wrist position. In order to allow for correction of the musician's wrist position while maintaining a natural playing feel, it is proposed that the learning aid (1) includes a receptacle (1a) for a mouthpiece (2) from which a thumb guide (1b) projects for positioning the thumb.
