Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If a substantial amount of combustible material is used in the fire starter, then the burn time is extended, but the manufacturing cost and transport cost increase

Engineering Contradiction:
Improveburn timeVSAvoidamount of combustible material
Core Design Contradiction:
Duration of action of moving objectVSQuantity of substance

Solution Approach 1:

The patent changes the physical and chemical parameters of the combustible material by incorporating specific additives (oxidizing agents, binding agents, and accelerants) that modify the combustion characteristics. This allows a smaller quantity of material to burn for an extended period with higher intensity, resolving the contradiction between burn time and material quantity.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The fire starter uses a composite material formulation combining combustible material with oxidizing agents, binding agents, and accelerants in specific proportions. This composite structure enables sustained combustion with reduced material quantity, addressing both the extended burn time requirement and the reduction of combustible material amount.

Inventive Principle:
Principle #40Composite materials

2Duration of action of moving object

If a substantial amount of combustible material is used in the fire starter, then the burn time is extended, but the manufacturing cost and transport cost increase

Engineering Contradiction:
Improveburn timeVSAvoidmanufacturing cost
Core Design Contradiction:
Duration of action of moving objectVSEase of manufacture

Solution Approach 1:

By modifying the combustion parameters through additives and achieving higher energy density, the patent reduces the total material quantity required, which directly lowers manufacturing costs while maintaining extended burn time.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a disposable fire starter that achieves extended functionality through optimized material composition rather than through quantity. This approach reduces manufacturing costs by using smaller amounts of carefully formulated materials instead of large quantities of simpler materials.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Duration of action of moving object

If a substantial amount of combustible material is used in the fire starter, then the burn time is extended, but the transport cost increases

Engineering Contradiction:
Improveburn timeVSAvoidamount of combustible material
Core Design Contradiction:
Duration of action of moving objectVSQuantity of substance

Solution Approach 1:

The patent achieves extended burn time with reduced material quantity by changing the combustion parameters through chemical additives that increase energy density and combustion efficiency, directly addressing the transport cost issue.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The fire starter incorporates functional zones with different material compositions - a core region with high-energy-density combustible material mixed with oxidizing agents for sustained burning, and an outer region with accelerants for rapid ignition. This local quality differentiation enables extended burn time with minimal total material.

Inventive Principle:
Principle #3Local quality

4Reliability

If ignition assistance is provided using traditional methods with twigs or wood chips, then the fire can be ignited, but the process is cumbersome and time-consuming

Engineering Contradiction:
Improveignition reliabilityVSAvoidease of use
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The fire starter is pre-formulated with all necessary components for reliable ignition - combustible material, oxidizing agents, and accelerants in optimal proportions. This preliminary preparation eliminates the need for users to gather and prepare traditional ignition materials like twigs and wood chips, making the process simple and reliable.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The fire starter is designed to be self-igniting through its internal chemical composition that facilitates easy ignition and sustained burning without requiring additional materials or complex preparation steps. The product serves itself by containing all necessary components for complete ignition and prolonged burning.

Inventive Principle:
Principle #25Self-service
