Solution Overview

Problem

Existing methods for storing and accessing hand-held grippers are inconvenient, leading to reduced efficiency and user strain, and existing holster systems fail to provide adjustable positioning and secure holding during movement.

Innovation Solution

An adjustable holster system with a belt, collar, and height adjuster that allows secure holstering of a hand-held gripper, featuring retractable fingers held in place by a collar with adjustable positioning and easy access, using a hook to connect the height adjuster to the belt.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional storage methods are used (setting gripper down or holding continuously), then the gripper can be stored or held, but user convenience is reduced and efficiency decreases

Engineering Contradiction:
Improveconvenience of storage and accessVSAvoidefficiency during tasks
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The holster system incorporates a height adjuster that allows dynamic repositioning of the collar along the belt. This enables the system to adapt to different user heights and preferences, providing convenient storage positioning while allowing quick access during tasks, thus resolving the contradiction between ease of operation and productivity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The collar acts as an intermediary component between the belt and the gripper. It provides a dedicated holding structure that secures the gripper in place during movement while allowing easy release when needed, improving both convenience and efficiency without requiring the user to constantly hold or set down the gripper.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If existing holster systems are used, then gripper storage is possible, but adjustable positioning for different heights is not provided

Engineering Contradiction:
Improveadjustability for different usersVSAvoidsecure holding during movement
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The height adjuster mechanism enables the collar to be repositioned vertically along the belt at different heights. This dynamic adjustment capability allows the system to adapt to users of different heights and preferences, providing both versatility and secure holding during movement, thereby resolving the contradiction between adaptability and ease of operation.

Inventive Principle:
Principle #15Dynamics

3Reliability

If existing holster systems are used, then gripper storage is possible, but secure holding during movement is not achieved

Engineering Contradiction:
Improvesecurity of gripper holdingVSAvoidaccess during tasks
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The collar serves as a specialized intermediary structure that interfaces with the gripper's retractable fingers. It provides a secure holding mechanism during movement while maintaining easy accessibility during tasks, thus resolving the contradiction between reliability and ease of operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Productivity

If repeated storage and access operations are performed, then gripper can be stored and accessed, but user strain increases

Engineering Contradiction:
Improvefrequency of storage and accessVSAvoiduser strain
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The collar provides a dedicated holding structure that supports the gripper during storage, reducing the burden on the user's muscles and joints. This intermediary support allows repeated storage and access operations without increasing user strain, while maintaining high productivity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The height adjuster allows the collar to be positioned at optimal heights for different users, creating an equipotential state where storage and access operations can be performed with minimal physical effort. This reduces user strain while enabling frequent operations, resolving the contradiction between productivity and harmful factors.

Inventive Principle:
Principle #12Equipotentiality

AI summary

An adjustable holster system including a belt to wrap around a waist of a user, a collar allowing holstering of a gripper within open space, the collar including at least three sides around the open space, a height adjuster connected to the collar to adjust a vertical position of the collar, and a hook to connect the height adjuster to the belt, wherein, when the user holsters the gripper within the open space, the sides of the collar hold retractable fingers of the gripper in place.
