Solution Overview

Problem

Existing devices for supporting objects during activities like fishing, hunting, or photography are cumbersome and do not adequately assist individuals with limited hand or arm mobility, making it difficult to maneuver and perform necessary actions effectively.

Innovation Solution

A supportive holder apparatus with an elongated body and support straps that couple to a user's appendage, allowing for secure attachment of elongated rods like fishing poles or monopod trigger sticks, providing stable support and ease of maneuverability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If traditional supportive holders are used to assist persons with physical limitations, then the person can hold objects for extended periods, but the devices are cumbersome to move around and do not allow easy maneuvering

Engineering Contradiction:
Improveduration of holding objectVSAvoidease of maneuvering
Core Design Contradiction:
Duration of action of moving objectVSEase of operation

Solution Approach 1:

The patent transitions the support mechanism from hand-held (horizontal dimension) to body-mounted (vertical dimension along the leg). The holder attaches to the leg via straps, moving the support point from the hands to the lower body, enabling hands-free operation while maintaining mobility and ease of maneuvering.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent introduces an intermediary structure (the leg-mounted holder with straps) between the person's body and the object (fishing pole, firearm, camera). This intermediary transfers the holding function from the hands to the leg, allowing the person to maintain stability while preserving upper body mobility for maneuvering.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If two hands are used to hold objects like fishing poles or firearms, then the objects can be controlled effectively, but persons with limited hand use cannot operate them

Engineering Contradiction:
Improvecontrol effectivenessVSAvoidadaptability to physical limitations
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal holding mechanism that can accommodate various objects (fishing poles, firearms, cameras) and various users regardless of hand capability. The leg-mounted holder provides a standardized interface that adapts to different physical limitations, allowing both able-bodied persons and those with hand impairments to operate the equipment effectively.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The holder design allows the user's body (leg) to serve the function of holding and stabilizing the object. The straps secure the object to the leg, enabling the leg itself to perform the support function that would traditionally require hands, thus making the system self-sufficient and adaptable to various physical capabilities.

Inventive Principle:
Principle #25Self-service

3Stability of the object's composition

If existing holders are designed to be stable, then they can support objects well, but they are cumbersome to move around frequently

Engineering Contradiction:
Improvestability of held objectVSAvoidcomplexity of moving device
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent employs dynamic straps that can be quickly adjusted and removed, allowing the holder to transition between stable (when attached) and mobile (when detached) states. The strap system provides secure attachment for stability during use, but can be easily released for frequent movement, reducing the complexity of relocating the device.

Inventive Principle:
Principle #15Dynamics

AI summary

Apparatuses, systems and methods of a supportive holder include an elongated body comprising a length extending from a first end to a second end, the elongated body further comprising a cylindrical receiving cavity at the first end configured to receive at least a portion of an elongated rod. Further the supportive holder includes support strap(s) each comprising a respective clip, each respective clip being configured to receive at least a portion of the elongated body, and at least one clip being configured to receive the second end of the elongated body. In addition, the support strap(s) are configured to couple to a user's appendage during use.
