Floor Mat with Irregular Soundproof Units to Isolate Percussive Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional floor mats have a poor soundproofing effect due to their design focusing on aesthetics and foot feel rather than sound insulation, leading to ineffective blocking of percussive sounds.
Innovation Solution
A floor mat with irregularly distributed soundproof units featuring different shapes and positions of soundproof structures such as press holes or scattering blocks, made from foamed materials like IXPE, EVA, or XPE, which absorb sound energy through frictional and viscous resistance, and heat conduction, and are produced using rollers with engraved structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional floor mats are designed with regular patterns for aesthetic appearance and uniform foot feel, then the appearance quality and foot feel are improved, but the soundproofing effect deteriorates because sound is evenly transmitted downwards
Solution Approach 1:
The patent applies asymmetry by designing soundproof units with irregular shapes, sizes, and distribution patterns instead of regular uniform patterns. The soundproof units include various geometric shapes (circles, squares, triangles, polygons) with different areas, arranged in an asymmetric layout that disrupts sound wave transmission while maintaining aesthetic appeal and uniform foot feel.
Solution Approach 2:
The patent implements local quality by creating soundproof units with non-uniform characteristics at different locations. Each soundproof unit has locally optimized properties (different shapes, sizes, and configurations) that collectively provide superior soundproofing across the entire floor mat surface while maintaining overall aesthetic consistency.
2Ease of manufacture
If floor mats are made with uniform thickness and regular embossing for manufacturing simplicity, then the manufacturing process is easy and cost-effective, but the sound insulation function is poor due to regular sound transmission patterns
Solution Approach 1:
The patent applies segmentation by dividing the floor mat surface into multiple discrete soundproof units with different shapes and sizes. These segmented units are arranged in an irregular pattern that disrupts sound transmission paths. The segmentation is achieved through embossing techniques that create distinct raised or recessed regions, maintaining manufacturing simplicity while improving soundproofing.
Solution Approach 2:
The patent implements asymmetry in the arrangement and configuration of soundproof units to disrupt regular sound transmission patterns. The asymmetric layout of variously shaped units creates irregular acoustic paths that scatter and absorb impact sound, while the embossing process maintains ease of manufacture through standard molding techniques.
3Ease of manufacture
If floor mats use simple embossing patterns for cost-effective production, then the production cost is low, but the soundproofing performance is insufficient due to lack of specialized sound insulation design
Solution Approach 1:
The patent applies universality by designing soundproof units that serve multiple functions: they provide aesthetic appearance, maintain uniform foot feel, and deliver effective soundproofing. The same embossing structures that create visual patterns also function as acoustic barriers, eliminating the need for separate specialized sound insulation components and keeping production costs low.
Solution Approach 2:
The patent utilizes porous or cellular structures within the soundproof units (including hollow regions and varying density areas) to enhance sound absorption. These porous characteristics are integrated into the embossing design, allowing the same manufacturing process to create both aesthetic patterns and acoustic functionality without increasing production cost.

AI summary
The disclosure belongs to the technical field of soundproof flooring, and discloses a floor mat and a floor. The floor mat includes a floor mat body made of foamed material. At least one surface of the floor mat body is provided with a number of soundproof units with the same area. Each of the soundproof unit has at least one soundproof structure. At least one of the numbers, shapes and distribution positions of the soundproof structures are different. The floor mat of the present disclosure can play a sound absorption effect; at the same time, a plurality of chaotic sounds are dispersed and mutually offset, which effectively isolates most of the sounds and has a good soundproof effect.
