Paddle Racket With 3D Web Core and Adhesive Layers

Solution Overview

Problem

Existing rackets require significant raw materials for production, leading to high costs and heavy weights, and their assembly using colloids results in issues like overflow, uneven adhesion, and time-consuming processes.

Innovation Solution

A paddle racket design featuring a frame body, a three-dimensional web core with channels and through holes, and double-sided adhesive layers that allow for the replacement of components, enabling quick and economical assembly and maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the striking member is made with considerable thickness and solid structure, then the racket has sufficient strength and durability, but it requires a large amount of raw materials which increases production cost and causes heavy weight

Engineering Contradiction:

ImprovestrengthVSAvoidweight

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The patent uses a hollow spherical shell structure with thin wall thickness (0.5-2mm) instead of solid thick striking members. The hollow sphere maintains structural strength while significantly reducing material usage and weight. The frame body is constructed as a hollow spherical shell with distributed support columns rather than solid mass.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The patent incorporates a honeycomb structure within the hollow spherical shell, creating a porous internal framework. This honeycomb structure provides structural reinforcement and impact resistance while maintaining low weight and high material efficiency. The porous design allows strength without solid filling.

Inventive Principle:

Principle #31Porous materials

2Strength

Engineering Contradiction:

ImprovestrengthVSAvoidraw material quantity

Core Design Contradiction:

StrengthVSQuantity of substance

Solution Approach 1:

The patent uses a hollow spherical shell structure with thin wall thickness (0.5-2mm) instead of solid thick striking members. The hollow sphere maintains structural strength while significantly reducing material usage and weight. The frame body is constructed as a hollow spherical shell with distributed support columns rather than solid mass.

This honeycomb structure provides structural reinforcement and impact resistance while maintaining low weight and high material efficiency. The porous design allows strength without solid filling.

Inventive Principle:

Principle #31Porous materials

3Ease of manufacture

If colloid is used to connect striking components to the frame body, then the components can be joined together, but it causes disadvantages of colloid overflowing, uneven adhesion and time-consuming process

Engineering Contradiction:

Improveassembly easeVSAvoidadhesion uniformity

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent extracts and eliminates the colloid adhesive from the assembly process. Instead of using liquid colloid that causes overflow and uneven adhesion, the design uses mechanical connection methods where support columns are inserted into corresponding holes, achieving precise and clean assembly without adhesive-related problems.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the chemical bonding system (colloid adhesive) with a mechanical connection system. Support columns with precise dimensions are inserted into matching holes in the striking surface and frame body, creating secure mechanical joints that eliminate adhesion uniformity issues and reduce assembly time.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
