Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a hard and durable outer shell with compressible foam inner layer is used, then head protection capability is improved, but weight increases

Engineering Contradiction:

Improvehead protection capabilityVSAvoidhelmet weight

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The helmet is divided into distinct functional segments: a hard outer shell for impact deflection, a shock-absorbing core with deformable head contact devices for shock attenuation, and ventilation channels for thermal management. Each segment performs its specific function independently, allowing optimization of each component's weight and performance characteristics.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The shock-absorbing core incorporates a deformable head contact device with a porous or cellular structure that provides shock absorption through controlled deformation and energy dissipation. This porous structure achieves effective shock protection with reduced material quantity and lower weight compared to solid foam constructions.

Inventive Principle:

Principle #31Porous materials

2Reliability

If more material is used for shock absorption, then protection capability is improved, but weight increases

Engineering Contradiction:

Improveshock absorption capabilityVSAvoidhelmet weight

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The head contact device is designed to be deformable rather than rigid, allowing it to dynamically respond to impact forces. The device deforms under load to absorb shock energy, then returns to its original shape, providing continuous protection without requiring excessive material mass.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The shock-absorbing core utilizes materials or structures with variable density or stiffness parameters, allowing optimized shock absorption performance with minimized material usage. The deformable head contact device changes its mechanical properties during deformation to maximize energy absorption efficiency.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If a solid structure is used for protection, then shock absorption is improved, but ventilation and comfort deteriorate

Engineering Contradiction:

Improveshock absorptionVSAvoidventilation and comfort

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The helmet structure is segmented to include dedicated ventilation channels that are separate from the shock-absorbing components. This segmentation allows the solid shock-absorbing core to maintain its protective function while ventilation pathways provide airflow for thermal management and wearer comfort.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The deformable head contact device acts as a flexible element between the rigid outer shell and the wearer's head, accommodating movement and providing comfort while maintaining shock absorption. This flexibility allows for better fit and ventilation without compromising protection.

Inventive Principle:

Principle #30Flexible shells and thin films
