Solution Overview

Problem

Conventional tie down devices for securing vehicles during transport often cause damage to the vehicle's handlebars and obstruct the driver's view, and users face difficulties in reaching and securing the straps without bending, leading to potential injury and instability.

Innovation Solution

A tie down strap system featuring a pair of strap assemblies with magnetic attachment means that secure to the top or side of the transport medium's cab, allowing easy access and preventing the need for users to bend or stretch, using neodymium magnets to hold the straps in place.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional tie down straps are attached to the handlebar of the vehicle, then the vehicle can be secured to the transport medium, but the handlebars may bend and cause damage to the fairing

Engineering Contradiction:

Improvevehicle securing reliabilityVSAvoiddamage to fairing and handlebars

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the attachment point from the handlebar area and relocates it to the cab of the transport medium. The tie-down system now attaches to the cab rather than the vehicle handlebars, eliminating the harmful bending forces on the handlebars and fairing while maintaining the vehicle securing function.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The cab of the transport medium serves as an intermediary attachment point between the tie-down strap and the vehicle. Instead of directly attaching to the vehicle handlebars, the strap connects to the cab, which then provides the anchoring point, thereby protecting the vehicle from damage.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If tie down straps are attached to the central steering portion of the handlebar, then the vehicle can be secured, but the driver's view is obstructed

Engineering Contradiction:

Improvevehicle securing reliabilityVSAvoiddriver's view clarity

Core Design Contradiction:

ReliabilityVSIllumination intensity

Solution Approach 1:

The attachment point is extracted from the central steering portion of the handlebar and relocated to the cab of the transport medium. This removes the obstruction to the driver's view while preserving the vehicle securing function, as the strap now attaches to the cab rather than blocking the driver's line of sight.

Inventive Principle:

Principle #2Taking out (Extraction)

3Device complexity

If the tie down strap is placed on the floor of the bed of the truck, then the strap can be stored, but the user cannot easily reach it while holding the motorcycle

Engineering Contradiction:

Improvestrap storage arrangementVSAvoiduser accessibility to strap

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The tie-down strap is preliminarily attached to the cab of the transport medium before the user needs to use it. This preliminary positioning allows the user to easily access and operate the strap without having to reach down to the floor of the truck bed, improving ease of operation while maintaining compact storage.

Inventive Principle:

Principle #10Preliminary action

4Reliability

If the user stretches and reaches the straps while holding the motorcycle, then the strap can be attached, but the suspension of the truck flexes and increases the risk of tipping over

Engineering Contradiction:

Improvestrap attachment reliabilityVSAvoidtruck stability

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The strap attachment point is extracted from a location requiring user stretching and reaching (floor of truck bed) and relocated to the cab area. This allows the user to attach the strap without stretching or bending, thereby maintaining truck stability and reducing the risk of tipping over while still achieving reliable strap attachment.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A tie down strap system for securing a vehicle to a platform of a transport medium comprises a first strap member, a second strap member, a connecting means having a first slot and a second slot and an attachment means at the second strap member. A front end of the first strap member is connected to a clamp member of the transport medium using a first securing means. A rear end of the first strap member is passed through the first slot to suspend therefrom and a first end of the second strap member is looped through the second slot and a second securing means and sewn thereon and a second end of the second strap member extends and suspends from the second securing means. When the vehicle is loaded on the platform, the first and second strap members secure the vehicle firmly to the platform of the transport medium.
