Solution Overview

Problem

Existing lighter holders are difficult to handle as they cover advertising imprints on lighters and can easily tear or wear out, leading to the lighter falling out, and they are not easily attachable to clothing or bags.

Innovation Solution

A lighter holding device with a dimensionally stable fastening ring and additional fastening eyelets that attach to the lighter container, allowing for secure attachment without covering the lighter's surface and enabling easy attachment to clothing or bags through pendants or chains.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the lighter holder encloses the lighter completely, then the lighter is securely held, but the advertising prints on the lighter are covered

Engineering Contradiction:
Improvelighter holding securityVSAvoidvisible lighter surface area
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The holder is designed as a fastening ring that attaches only to a specific section (lower end or upper end) of the lighter container rather than enclosing the entire lighter. This segmentation allows the lighter to remain partially exposed, preserving advertising prints while still providing secure attachment through the fastening structure.

Inventive Principle:
Principle #1Segmentation

2Area of stationary object

If the fastening ring is made thin to minimize coverage, then more lighter surface is visible, but the ring may tear or become loose during use

Engineering Contradiction:
Improvevisible lighter surface areaVSAvoidfastening ring durability
Core Design Contradiction:
Area of stationary objectVSStrength

Solution Approach 1:

The fastening ring is designed with dimensionally stable material properties and an optimized thickness that provides sufficient local strength at the attachment section while maintaining overall thinness. The ring's cross-sectional dimensions are specifically engineered to balance visibility requirements with mechanical durability, preventing tearing and loosening during normal use.

Inventive Principle:
Principle #3Local quality

3Reliability

If the lighter holder is attached to the lighter, then the lighter is secured, but the holder can easily tear or become loose causing the lighter to fall out

Engineering Contradiction:
Improvelighter attachment securityVSAvoidholder material strength
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The holder is constructed from dimensionally stable materials that combine rigidity and strength properties, ensuring the fastening ring maintains its structural integrity during use. The material selection prioritizes resistance to tearing and loosening while allowing the ring to conform to the lighter container section it attaches to.

Inventive Principle:
Principle #40Composite materials

4Adaptability or versatility

If the fastening element is made of elastic silicone or rubber material for flexibility, then the holder can conform to the lighter, but the material can easily tear during use

Engineering Contradiction:
Improveholder conformability to lighterVSAvoidfastening element durability
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The fastening element's material parameters are optimized by selecting dimensionally stable materials with appropriate elasticity and tensile strength. The material properties are specifically chosen to provide sufficient flexibility for conforming to the lighter container shape while maintaining high resistance to tearing and degradation during repeated use.

Inventive Principle:
Principle #35Parameter changes
