Racket Grip with Segmented Protruding Bodies for Multi-Grip Guidance

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing racket grip devices fail to provide consistent and adjustable guidance for novice players to achieve precise grip positioning, limiting their ability to learn and switch between different grips effectively.

Innovation Solution

A grip device with at least two externally protruding bodies of different shapes and sizes, positioned circumferentially on the racket handle, providing guiding surfaces for the fingers and allowing adjustable attachment to accommodate various grip styles, including releasable fastening means for customization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single angular position device is used to guide grip, then one specific grip is guided, but other grips cannot be guided

Engineering Contradiction:

Improvegrip guidance capabilityVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The grip guiding device is segmented into multiple independent protruding bodies (at least two) positioned at different angular locations on the racket handle. Each protruding body can independently guide different grip positions, allowing the device to guide multiple grip types simultaneously without requiring a single complex adjustable mechanism.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The device employs protruding bodies with different shapes and sizes that can accommodate dynamic transitions between various grip styles. The asymmetric design allows players to smoothly switch between grips by naturally adapting their hand positioning around the different protruding bodies during play.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If identical protruding bodies are used, then the device structure is simple, but different grip positions cannot be distinguished

Engineering Contradiction:

Improvegrip position differentiationVSAvoidprotruding bodies configuration

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The protruding bodies are designed with asymmetric characteristics - they have different shapes and/or sizes from each other. This asymmetry creates distinct tactile and visual cues for different grip positions, enabling players to easily distinguish and identify correct grip placements without confusion.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

Each protruding body possesses unique local qualities in terms of shape and size, optimized for guiding specific grip positions. For example, one protruding body may be larger and more rounded for guiding the index finger in a continental grip, while another may be smaller and more angular for guiding middle finger placement in an eastern grip.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If fixed grip positioning is provided, then grip guidance is firm, but adaptability to different hand sizes and grip styles is limited

Engineering Contradiction:

Improvehand size accommodationVSAvoidgrip position precision

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The combination of multiple protruding bodies with varying shapes and sizes creates a universal guiding system that can accommodate different hand sizes, ages, and grip preferences. The device serves multiple functions by guiding various grip types (continental, eastern, semi-western, western, etc.) simultaneously, making it adaptable to diverse player needs while maintaining precise grip positioning guidance.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A grip device for a racket includes at least two externally protruding bodies, a primary body and a secondary body, extending from the outer surface of the racket handle and being located circumferentially distanced from each other. The racket handle has a central longitudinal axis A, wherein the primary body is of a quadrilateral or triangular construction.
