Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If pre-selected printed designs are used on the lighter surface, then manufacturing cost is reduced and production is simplified, but design variety and customer customization options are limited

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoiddesign variety
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies the dynamics principle by replacing static printed designs with a dynamic electronic display system. The display can change its content based on user input, allowing the lighter to adapt its appearance over time. This resolves the contradiction by enabling design variety without complicating the manufacturing process, as the display hardware remains constant while the software content can be updated.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent utilizes parameter changes by allowing the display content to be modified through software updates and user configuration rather than physical redesign. The hardware parameters (display structure) remain fixed during manufacturing, while the functional parameters (displayed content) can be changed indefinitely, resolving the contradiction between manufacturing simplicity and design variety.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If complex systems with thousands of different designs are created to accommodate unlimited consumer preferences, then design variety is improved, but manufacturing cost and system complexity increase significantly

Engineering Contradiction:
Improvedesign customizationVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the copying principle by using a single display hardware unit that can replicate multiple different designs through software control. Instead of manufacturing thousands of different physical lighters, one lighter unit can display numerous different designs by loading different content, thereby achieving high adaptability without proportional increase in system complexity.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent implements universality by designing a single lighter system that can perform multiple design functions through one display unit. The display serves multiple purposes by displaying different content based on user preferences, effectively making one device capable of providing thousands of different design options without requiring separate systems for each design.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If an electronic display system is integrated into the flame producing assembly for customizable designs, then design variety and user configuration options are improved, but device size and internal complexity increase

Engineering Contradiction:
Improvecustomization capabilityVSAvoidinternal complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the extraction principle by separating the display control functions from the core flame producing mechanism. The display system is extracted as a separate module that can be independently controlled, allowing customization capabilities to be added without fundamentally redesigning the entire lighter system. This reduces internal complexity by maintaining modular architecture where the display is an add-on rather than an integrated core component.

Inventive Principle:
Principle #2Taking out (Extraction)

4Adaptability or versatility

If continuous power supply is provided to the electronic display for maintaining customized images, then display functionality is improved, but energy consumption increases

Engineering Contradiction:
Improvedisplay functionalityVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent applies periodic action by implementing power consumption only during specific events (image updates, user interaction) rather than continuous operation. The display maintains its state without continuous power supply, consuming energy periodically when content needs to be changed or refreshed. This resolves the contradiction by maintaining display functionality while significantly reducing overall energy consumption compared to continuous operation.

Inventive Principle:
Principle #19Periodic action
