Solution Overview

Problem

Existing stabilizers for vehicle attachments are prone to wear due to unintentional rotation and relative movement of components, leading to increased wear and reduced durability.

Innovation Solution

A stabilizer design featuring a locking device connected to the second actuating and connecting elements, with a bracket and locking element to prevent relative rotation and movement, and a telescopic mechanism for adjustable length, ensuring stable attachment to varying widths.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a spring clip is used to prevent rotation of the adjusting element, then the stabilizer can be adjusted to different lengths, but the spring clip and locking collar experience increased wear due to relative movement during compression and rebound

Engineering Contradiction:
Improveadjustability of stabilizer lengthVSAvoidwear resistance of locking components
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

A locking device with a bracket and locking element is introduced as an intermediary mechanism between the first and second adjusting elements. The bracket is pivotally connected to one adjusting element while the locking element is connected to the other, creating a mediating structure that prevents rotation without requiring direct engagement between the adjusting elements themselves.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

Instead of using a spring clip that actively engages with a locking collar (as in prior art), the invention inverts the approach by using a locking element that can be positioned to prevent rotation. The locking device uses a bracket that pivots to engage with a locking element, reversing the traditional active-passive engagement relationship and eliminating the harmful relative movement during compression and rebound.

Inventive Principle:
Principle #13The other way round (Inversion)

2Adaptability or versatility

If the second adjusting element can rotate relative to the second connecting element for length adjustment, then the stabilizer adapts to different attachment widths, but unintentional rotation occurs causing wear and length changes

Engineering Contradiction:
Improveadaptation to different attachment widthsVSAvoidunintentional rotation and wear
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The locking device incorporates dynamic elements including a bracket that can pivot and a locking element that can be positioned in different states. During adjustment, the bracket pivots to allow rotation, and after adjustment, the locking element engages to prevent further rotation. This dynamic design enables the system to transition between adjustable and locked states, accommodating different attachment widths while preventing unintentional rotation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The locking device is designed to automatically engage and disengage based on the operational state. When the stabilizer is adjusted, the bracket naturally pivots to the engaged position, and the locking element self-locks without requiring additional components or complex mechanisms. The system serves itself by using the movement during adjustment to facilitate the locking action.

Inventive Principle:
Principle #25Self-service
