Solution Overview

Problem

Existing LED candle lights face issues such as unstable battery contact, inconvenient switch control, internal parts easily falling off, and safety hazards due to removable battery covers that can be easily accessed by children.

Innovation Solution

A switching device and LED candle light design that utilizes a height difference between the end of an arc groove and a limit slot to securely lock the battery cover, ensuring stable electrical connections and preventing easy removal by children, while also incorporating a hook&hole assembly and sliding track for switch operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If the battery cover is made removable for easy battery replacement, then the ease of manufacture and maintenance is improved, but the safety hazard increases due to children being able to easily access and remove the battery cover

Engineering Contradiction:

Improvebattery replacement convenienceVSAvoidsafety hazard from child access

Core Design Contradiction:

Ease of repairVSObject-affected harmful factors

Solution Approach 1:

The battery cover is segmented into two functional parts: a decorative outer cover and an inner battery compartment cover. The inner cover includes a pressing structure that must be actively engaged to release the battery, creating a two-step safety mechanism that prevents accidental or child access while maintaining intentional accessibility for adults

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A pressing structure acts as an intermediary mechanism between the user and the battery compartment. This intermediate component requires deliberate pressing action to disengage the locking mechanism, serving as a safety barrier that children cannot operate while allowing intentional battery replacement

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the battery cover is made secure and difficult to remove for safety, then the safety hazard is reduced, but the ease of operation deteriorates as users may have difficulty accessing the battery

Engineering Contradiction:

Improvesafety hazard reductionVSAvoidbattery access convenience

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The pressing structure is designed to be self-latching through its interaction with the limiting groove and arc groove. Once engaged, the structure automatically locks the battery cover in place without requiring continuous external force, providing secure retention while allowing easy intentional release through a simple pressing motion

Inventive Principle:

Principle #25Self-service

3Device complexity

If the LED candle light uses traditional paraffin candles, then the simplicity of the device is improved, but the harmful factors increase due to smoke production and environmental pollution

Engineering Contradiction:

Improvesimplicity of candle structureVSAvoidsmoke and pollution

Core Design Contradiction:

Device complexityVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the chemical combustion mechanism of paraffin candles with an electrical LED lighting system powered by a battery. This substitution eliminates smoke and pollution generation while maintaining the visual effect of candlelight through LED beads arranged to simulate flame appearance

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The energy source parameter is changed from chemical energy (paraffin combustion) to electrical energy (battery-powered LED). This fundamental parameter change transforms the harmful combustion process into a clean, smokeless electrical lighting system while preserving the aesthetic function

Inventive Principle:

Principle #35Parameter changes

4Reliability

If the LED candle light uses a large battery for stable power supply, then the reliability is improved, but the volume of the device increases making it less portable

Engineering Contradiction:

Improvepower supply stabilityVSAvoiddevice size

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The battery is pre-installed and pre-positioned within the housing structure during manufacturing. The housing itself serves as a protective enclosure that secures the battery in an optimal position, eliminating the need for additional battery mounting structures and reducing overall device volume while ensuring stable power supply

Inventive Principle:

Principle #10Preliminary action
