Solution Overview

Problem

Existing hand grips fail to provide simultaneous anti-skidding, shock-absorbing, and breathable functionalities, despite improvements in user hold and grasping.

Innovation Solution

A surface with numerous fine pillars made of resilient and deformable plastic material, arranged in high density, which are integrally connected to the surface and feature a bore and flat end face, allowing for multi-directional anti-skidding, shock-absorbing, and breathable capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If protrusions or knurls are added to the surface to improve grasping, then user hold is improved, but the article cannot provide anti-skidding, shock-absorbing and breathable capacities simultaneously

Engineering Contradiction:
Improveuser holdVSAvoidmulti-functionality
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The fine pillars are designed to perform multiple functions simultaneously: they provide anti-skidding through friction, shock-absorbing through elastic deformation, and breathable through air passage formation. This single structural element replaces what would traditionally require multiple different surface features, achieving multi-functionality without adding device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The fine pillars are arranged with sufficient spacing to create air passages between them, effectively creating a porous surface structure. This allows the solid material to provide mechanical functions (anti-skidding and shock-absorbing) while simultaneously allowing air flow through the gaps, achieving breathable capacity without compromising the structural integrity needed for the other functions.

Inventive Principle:
Principle #31Porous materials

2Ease of operation

If fine pillars are arranged in high density to provide anti-skidding and shock-absorbing, then grasping capability is improved, but breathability may be compromised

Engineering Contradiction:
Improvegrasping capabilityVSAvoidbreathability
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The design optimizes specific parameters of the fine pillars including their diameter (0.5-2mm), height (1-5mm), and spacing (0.5-2mm) to achieve the desired balance. By carefully controlling these dimensional parameters, the surface provides sufficient density for anti-skidding and shock-absorbing while maintaining adequate gaps for breathability. The parameter optimization allows all three functions to coexist effectively.

Inventive Principle:
Principle #35Parameter changes

AI summary

An article (10, 40, 50) includes a body (12, 42, 52) having at least a holding or resting surface (16, 426, 56), and a plurality of spaced-apart fine pillars (22, 44, 54) made of a resilient and deformable plastic material and projected from the holding or resting surface of the body. Each of the spaced-apart fine pillars includes a body portion (24) with a bore (26) defining a longitudinal axis (X-X'), a base end (28) and a free end (30). The base end of the fine pillar is integrally connected with the holding or resting surface the body. The body portion of the fine pillar extends from the base end along the longitudinal axis to the free end in a predetermined height. The fine pillars can be able to deform elastically when subjected to even a minimum pressure to provide the anti-skidding, shock-absorbing and breathable capacities.
