Solution Overview

Problem

Rental karts require effective peripheral protection to ensure safety due to inexperienced drivers, but existing solutions often stiffen the chassis, restricting torsion and compromising performance and driving experience.

Innovation Solution

A kart design featuring a peripheral protection assembly with separate protection elements connected by pivot connections allowing horizontal rotation, enabling chassis deformation and improved torsional flexibility without constraining the chassis, thus enhancing safety and performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If rigid peripheral protection is added to the chassis, then safety protection is improved, but chassis torsion flexibility deteriorates

Engineering Contradiction:
Improvesafety protectionVSAvoidchassis torsion flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The peripheral protection is divided into multiple separate protection elements rather than a single rigid structure. These elements are connected through pivot connections, allowing each segment to move independently and accommodate chassis deformation while maintaining protective function.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The protection system transitions from a static rigid structure to a dynamic articulated structure. The pivot connections enable the protection elements to rotate and adapt their configuration, allowing the chassis to torsion freely while the protection remains intact and functional.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If peripheral protection elements are fixed to the chassis, then structural stability is improved, but chassis deformation capability deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidchassis deformation capability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The protection elements are connected to the chassis and to each other through pivot connections that allow rotational movement. This dynamic connection maintains structural integrity and stability while permitting the chassis to deform and torsion during operation or impact events.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connection parameters between protection elements and chassis are designed to allow controlled movement. The pivot connections provide a specific degree of freedom that maintains structural stability in normal conditions while allowing deformation when needed, changing the mechanical parameters from rigid to semi-rigid.

Inventive Principle:
Principle #35Parameter changes
