Solution Overview

Problem

Existing solutions for public transport vehicles do not effectively prevent direct contact between passengers and vehicle surfaces during epidemics, lack a secure grip, and fail to encourage social distancing.

Innovation Solution

A holding assembly comprising a support and a gripping device with reversible assembly elements, including an orifice and a projecting member, allowing passengers to securely attach the gripping device to the support without direct contact, while encouraging distancing through strategically placed supports.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a telescopic rod with suction cup is used as a handle, then passengers can avoid direct contact with vehicle surfaces, but the mechanism becomes complex and expensive

Engineering Contradiction:

Improvedirect contact with vehicle surfacesVSAvoidmechanism complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent employs simple, inexpensive components such as a gripping element with a projecting member and a support with an orifice. These components are designed to be simple and cost-effective while still providing the necessary function of preventing direct contact with vehicle surfaces during epidemics.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Adaptability or versatility

If a telescopic rod with suction cup is used, then temporary attachment is possible, but the grip security is insufficient during strong jolts

Engineering Contradiction:

Improvetemporary attachment capabilityVSAvoidgrip security

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The gripping element is inserted through the orifice of the support, with the projecting member passing through the orifice to create a nested configuration. This nesting provides secure attachment while maintaining the ability to be easily assembled and disassembled, ensuring reliability during vehicle movement.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Object-affected harmful factors

If handles are provided at various locations, then passengers can avoid direct contact, but social distancing is not encouraged

Engineering Contradiction:

Improvedirect contact with surfacesVSAvoidsocial distancing encouragement

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The support is designed with multiple orifices arranged in a specific pattern, where each orifice is positioned to serve a specific location. This local arrangement of orifices encourages passengers to maintain social distancing by providing designated attachment points that are spaced appropriately throughout the vehicle.

Inventive Principle:

Principle #3Local quality
