Solution Overview

Problem

Existing harmonica holders require two hands to mount and dismount, are cumbersome, and often interfere with optimal microphone positioning or vocal performance, pushing microphone gain to feedback limits.

Innovation Solution

A one-piece, hand-operable harmonica holder that attaches to a microphone using its own weight and a hook, allowing quick attachment and detachment with one hand, and features a groove for easy harmonica exchange without moving parts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional harmonica holders use screws, bolts, brackets and magnets to mount to a microphone stand, then the harmonica can be securely mounted, but it requires 2 hands to apply and remove and is generally cumbersome

Engineering Contradiction:
Improvesecure mountingVSAvoidmounting operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The holder is divided into separate functional components: a mounting bracket that attaches to the mic stand, a holder body that secures the harmonica, and a release mechanism. This segmentation allows the harmonica to be quickly released from the holder body while the bracket remains mounted on the stand, enabling one-handed operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The holder incorporates a dynamic release mechanism that transitions from a locked state (securing the harmonica) to an unlocked state (releasing the harmonica). This mechanical transition allows quick one-handed operation for both mounting and removing the harmonica, improving ease of operation while maintaining secure mounting during play.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If neck supported harmonica holder is used, then the harmonica can be held, but it is cumbersome while using it and requires 2 hands to exchange harmonicas to a different key

Engineering Contradiction:
Improveharmonica holding capabilityVSAvoidharmonica exchange
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The holder separates the harmonica clamping function from the mounting function, allowing the harmonica to be quickly exchanged in the holder body while the mounted bracket remains in place. This enables one-handed harmonica exchange operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The holder body acts as an intermediary between the mounted bracket and the harmonica, providing a quick-release interface that allows harmonica exchange without manipulating the mounting bracket. This intermediary mechanism enables easy one-handed operation for harmonica changes.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If springs, magnets, clamps and tighteners are used to hold the harmonica, then the harmonica can be secured, but it requires 2 hands to manipulate

Engineering Contradiction:
Improveharmonica securingVSAvoidmanipulation operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The holder uses a dynamic mechanical latch system that automatically locks when the harmonica is inserted and can be quickly released by a single hand operation. This dynamic mechanism provides reliable securing without requiring two-handed manipulation for insertion or removal.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The holder incorporates a self-latching mechanism that automatically secures the harmonica upon insertion without requiring manual adjustment or two-handed operation. The mechanical design allows the harmonica to be held securely through its own insertion action, with release requiring only one hand.

Inventive Principle:
Principle #25Self-service

4Ease of operation

If duct tape harmonicas to the face of the microphone, then good placement is guaranteed, but it interferes with optimal microphone positioning and vocal performance

Engineering Contradiction:
Improveharmonica placementVSAvoidmicrophone positioning interference
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The holder acts as an intermediary device that positions the harmonica relative to the microphone without requiring direct attachment to the microphone body. The bracket mounts to the mic stand while the holder body positions the harmonica, maintaining optimal microphone positioning for vocals while securing the harmonica for easy access.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system separates the harmonica mounting function from the microphone mounting function, allowing independent optimization of both. The bracket handles the microphone stand attachment while the holder body handles the harmonica positioning, preventing interference between the two functions and maintaining optimal positioning for both harmonica play and vocal performance.

Inventive Principle:
Principle #1Segmentation

AI summary

The Easy application harmonica holder is a 1-piece harmonica holder that holds itself in place using leverage provided by the hook while engaged with the Microphone. It is placed over top of a microphone being supported by a microphone stand and microphone holder, that keeps the harmonica positioned directly in front of the microphone allowing the musician to play other handheld instruments, while playing the harmonica by mouth, simultaneously. The difference between this device, the Easy Application Harmonica Holder and prior harmonica holding devices is, it is 1-piece, and it does not require you to remove or add any parts or pieces to put it on the microphone or take it off. It mounts directly to the top of the microphone. It keeps the harmonica in place in a groove on the faceplate. It is limited to the popular raised-back-edge harmonicas. What makes this Harmonica Holder Unique from prior harmonica holders is, it uses no mechanical fasteners, screws, springs or clamps to hold it in place and uses no mechanical fasteners, brackets, springs or magnets to hold the harmonica in place.
