Solution Overview

Problem

Existing stabilizer assemblies for vehicles, such as tricycles, face limitations in payload capacity due to outward forces generated by strut dampers, which require substantial reinforcement, increasing the vehicle's mass and reducing comfort under load.

Innovation Solution

Incorporating a flexible link system between the arms of the stabilizer assembly, which balances tensile forces from a load-carrying device with a bracing system, preventing arm deflection and allowing increased payload without significant mass addition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If strut-mounted shock absorbers are used to connect arms to chassis, then damping and comfort are improved, but outward forces push arms apart requiring substantial reinforcement that increases vehicle weight

Engineering Contradiction:
Improvehandling comfortVSAvoidvehicle mass
Core Design Contradiction:
Ease of operationVSWeight of moving object

Solution Approach 1:

A flexible link is introduced as an intermediary element between the two arms. This flexible link carries a load-bearing device that extends into the inter-space between the arms, transferring loads and generating tensile forces that balance the outward forces from the shock absorbers, eliminating the need for substantial arm reinforcement.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The load-bearing device is extracted from the traditional arm structure and placed on a separate flexible link that spans the inter-space between arms. This separates the load-carrying function from the stabilizing arm structure, allowing arms to be lighter while still supporting payloads.

Inventive Principle:
Principle #2Taking out (Extraction)

2Strength

If arms are substantially reinforced to withstand outward forces from shock absorbers, then arm strength and stability are improved, but vehicle mass increases significantly

Engineering Contradiction:
Improvearm strengthVSAvoidvehicle mass
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The flexible link with load-bearing device acts as a mediator that provides the necessary structural support for carrying loads. This allows the arms themselves to remain lighter since they no longer need to independently withstand all outward forces from the shock absorbers - the flexible link system shares this load-carrying responsibility.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Quantity of substance

If payload capacity is increased beyond 100 kg, then cargo transport capability is improved, but excessive external forces are generated on arms requiring reinforcement

Engineering Contradiction:
Improvepayload capacityVSAvoidarm strength
Core Design Contradiction:
Quantity of substanceVSStrength

Solution Approach 1:

The flexible link system with load-bearing device extending into the inter-space between arms serves as a mediator that directly supports increased payloads. As payload capacity exceeds 100 kg, the flexible link generates proportionally larger tensile forces that balance the increased outward forces from shock absorbers, allowing high payload capacity without requiring substantially reinforced arms.

Inventive Principle:
Principle #24Intermediary (Mediator)
