Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional lighting devices with foldable support legs often suffer from looseness in the folded state, leading to potential damage and automatic unfolding issues.

Innovation Solution

A base assembly with a sliding element and guide rod system, featuring rotating ends and support legs that can be locked in a folded state using locking elements, allowing for automatic unfolding without manual operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If support legs are made foldable for easy storage, then portability is improved, but the support legs become loose and prone to automatic unfolding

Engineering Contradiction:

ImproveportabilityVSAvoidstability in folded state

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The locking element is pre-configured to automatically engage with the support leg when it reaches the folded position, preventing automatic unfolding without requiring user intervention during storage

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The support leg structure includes a self-locking mechanism where the locking element automatically locks the support leg in the folded state through its own movement, without needing external locking devices or manual operations

Inventive Principle:

Principle #25Self-service

2Volume of moving object

If support legs are made foldable for compact storage, then device compactness is improved, but the support legs suffer from looseness and potential damage

Engineering Contradiction:

Improvestorage volumeVSAvoidstructural integrity

Core Design Contradiction:

Volume of moving objectVSStrength

Solution Approach 1:

The locking element is pre-positioned to engage with the support leg before any damage can occur from loose movement, preventing structural damage during storage and transport

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The locking mechanism provides preemptive structural support to the support leg in the folded state, preventing the looseness that would lead to damage during storage and handling

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A base assembly includes a mounting structure and a support structure. The mounting structure includes a base body, a main body, and a guide rod provided between the base body and the main body. The support structure includes a sliding element and support legs. The sliding element is slidably connected to the guide rod. Each of the support legs is provided with a rotating end and a support end that are arranged opposite to each other. The rotating end is rotatably connected to the sliding element. The sliding element is slidable toward the main body to drive a plurality of support ends to approach each other, such that the base assembly is in a folded state. One of the base body and the support leg is provided with a first locking element, and the other of the base body and the support leg is provided with a second locking element.
