Cognitive Training Handle Adjustable String Clamp Mechanism

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current cognitive training handles do not allow for easy and precise adjustment of the string length, leading to difficulties in controlling the ball during training, especially when the ball's trajectory fluctuates, causing the user to lose the benefits of the training device.

Innovation Solution

The handle features a clamp mechanism with side walls that periodically space apart to define retaining and passage regions, allowing for adjustable string length by pinching the string in the retaining region and removing it for adjustment, along with a guide mechanism to facilitate movement and a case with an outlet orifice for comfortable handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the string length is adjusted using existing handles, then the length can be changed, but the adjustment is not easy and precise

Engineering Contradiction:

Improvestring length adjustment precisionVSAvoidstring length adjustment ease

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The adjusting means is divided into side walls with periodically spaced retaining regions and passage regions, allowing the string to be segmented between these regions for precise positioning at multiple discrete length settings

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The adjusting means acts as an intermediary mechanism between the string and the handle body, providing a dedicated interface for easy and precise string length adjustment through the retaining and passage regions

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the ball trajectory has minimal fluctuation, then the training precision is maintained, but the impact on the string is amplified to the handle making the ball difficult to control

Engineering Contradiction:

Improvetraining device effectivenessVSAvoidball control ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The string is pre-secured in the retaining region before training begins, ensuring proper tension and attachment. This preliminary securing action prevents excessive string movement and impact transmission to the handle during ball trajectory fluctuations

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The adjusting means extracts the string length adjustment function from the overall handle structure, allowing independent optimization of string securing without affecting the handle's ball control functionality

Inventive Principle:

Principle #2Taking out (Extraction)

3Reliability

If the string is securely attached to prevent detachment, then reliability is improved, but the ability to adjust length quickly is reduced

Engineering Contradiction:

Improvestring attachment securityVSAvoidtime to adjust string length

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The side walls create periodic retaining regions and passage regions along the string path, allowing the string to be quickly moved between discrete positions for adjustment while maintaining secure attachment at each position through the retaining regions

Inventive Principle:

Principle #19Periodic action
