Solution Overview

Problem

Conventional foldable cutting mats lack a comprehensive antiskid structure, leading to slipping during use, and the separate antiskid pads on baseboards are difficult to secure and recycle, causing pollution and uneven folding.

Innovation Solution

A foldable cutting mat design with printed antiskid layers on both baseboards and a foldable sheet, featuring a pre-folding line and a thickness of 0.05 mm to 0.5 mm, ensuring complete abutment and a comprehensive antiskid effect without additional pads, using soft PVC or non-slip ink for recyclability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a thick antiskid pad is adhered to the back of baseboards, then antiskid performance is improved, but the baseboards cannot abut completely and a triangle space is formed after folding

Engineering Contradiction:

Improveantiskid performanceVSAvoidabutment completeness

Core Design Contradiction:

ReliabilityVSShape

Solution Approach 1:

The patent changes the thickness parameter of the antiskid layer from conventional over 1.5 mm to 0.05-0.5 mm, and changes the material form from separate foam pads to printed layers integrated with the baseboard material, enabling complete abutment while maintaining antiskid function

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The antiskid layer is merged with the baseboard material through printing, creating an integrated structure where the antiskid function is combined with the baseboard itself, eliminating the need for separate thick pads

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If separate antiskid pads are used on baseboards, then antiskid function is provided, but the pads are difficult to secure and may shrink or deteriorate

Engineering Contradiction:

Improveantiskid functionVSAvoidpad stability

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The antiskid layer is printed directly onto the baseboard, merging the antiskid function with the baseboard structure itself, eliminating separate pads that can shrink or deteriorate

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces the mechanical adhesion system (separate pads glued to baseboards) with a printed layer system where the antiskid material is deposited directly on the baseboard surface, eliminating the need for additional adhesion and improving stability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If separate antiskid pads are used on baseboards, then antiskid performance is achieved, but the pads cannot be recycled with the baseboards causing pollution

Engineering Contradiction:

Improveantiskid performanceVSAvoidpollution

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The antiskid layer is integrated with the baseboard through printing, creating a unified structure that can be recycled together, eliminating the pollution problem of separate non-recyclable pads

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated printed structure allows the entire cutting mat including the antiskid layer to be recycled as a single unit, improving environmental sustainability by enabling recovery and reuse of materials

Inventive Principle:

Principle #34Discarding and recovering

4Device complexity

If no antiskid structure is provided on the foldable sheet, then the structure is simple, but the cutting mat cannot provide comprehensive antiskid effect

Engineering Contradiction:

Improvestructure simplicityVSAvoidcomprehensive antiskid effect

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent divides the antiskid structure into multiple segments: printed antiskid layers on both baseboards and on the foldable sheet, providing comprehensive coverage throughout the entire cutting mat structure

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The antiskid function is merged into the foldable sheet itself through printing, integrating the antiskid property with the connecting element rather than adding separate components

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A cutting mat includes two baseboards, at least one foldable sheet connecting the two baseboards and multiple back antiskid units. Each baseboard has a cutting surface formed on a front thereof and a back, wherein the two baseboards are adjacent to each other and the foldable sheet is attached to the back of each of the two baseboards for connecting the two adjacent baseboards. The foldable sheet has a pre-folding line formed thereon along an abutment between the two adjacent baseboards such that the foldable sheet is folded along the pre-folding line to make the two baseboards completely abutting each other. The multiple back antiskid units are formed by printed antiskid layers that are distributed on the back of each of the two baseboards and a back of the foldable sheet.
