Solution Overview

Problem

Traditional protective pads face limitations such as poor durability under repeated washing, inability to transfer moisture and air, and weight issues, which affect their effectiveness in absorbing and distributing impact forces.

Innovation Solution

A protective pad design comprising an impact shell and a damping component with a coupling frame, where the damping component is formed by interconnected joining members and extension members that absorb impact forces, providing customizable impact attenuation through geometric configurations and materials like elastomeric materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional foam materials are used for protective padding, then impact absorption is provided, but durability under repeated washing deteriorates

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent transitions from foam materials to a lattice structure made of elastomeric material, changing the physical parameters of the damping component. This new structure maintains impact absorption while being washable and durable, directly resolving the contradiction between impact protection and washing durability

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The protective pad combines an impact shell with a lattice-based damping component made of elastomeric material. This composite construction provides both the structural integrity needed for durability and the damping properties needed for impact absorption, while the elastomeric material allows repeated washing without degradation

Inventive Principle:
Principle #40Composite materials

2Object-affected harmful factors

If traditional foam materials are used, then impact force distribution is achieved, but moisture and air transfer capability deteriorates

Engineering Contradiction:
Improveimpact force distributionVSAvoidmoisture and air transfer
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The lattice structure inherently provides porosity with voids between the connecting members. This porous structure allows moisture and air to pass through the damping component, resolving the contradiction between maintaining impact distribution and enabling moisture/air transfer. The open lattice architecture facilitates breathability while preserving the distributed impact absorption mechanism

Inventive Principle:
Principle #31Porous materials

3Force

If traditional foam padding is used, then impact absorption is provided, but weight increases

Engineering Contradiction:
Improveimpact absorptionVSAvoidprotective pad weight
Core Design Contradiction:
ForceVSWeight of moving object

Solution Approach 1:

The damping component is segmented into a lattice structure with discrete connecting members and voids, rather than using solid foam material. This segmentation reduces material quantity while maintaining the distributed impact absorption function, thereby reducing the overall weight of the protective pad while preserving impact protection capabilities

Inventive Principle:
Principle #1Segmentation

AI summary

Embodiments of the present invention relate to a protective pad that is comprised of an impact shell and a damping component. The damping component may be formed by a plurality of connecting members that are separated from the impact shell by a plurality of extension members that extend between the damping lattice and the impact shell. The damping component may also be formed by a sheet-like form that is separated from the impact shell by a plurality of extension members that extend between the damping sheet and the impact shell. The damping component is formed from an elastomer that aids in absorbing a portion of an impact force that is distributed across the damping component by the impact shell. The dampening component may be affixed to the impact shell by way of a coupling frame that is incorporated into the impact shell.
