Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If rigid structures are used to absorb vibrations, then vibration absorption is improved, but impact energy is transmitted to the frame causing safety risks

Engineering Contradiction:
Improvevibration absorptionVSAvoidimpact energy transmission
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The protection assembly is divided into multiple independent ring bodies (at least three) distributed along the frame perimeter. Each ring body acts as an independent energy absorption unit, preventing concentrated stress transmission to the frame while maintaining overall structural integrity through distributed segmentation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The ring bodies are designed with specific geometric parameters (cross-sectional area, wall thickness, material properties) that enable elastic deformation under impact loads. By optimizing these parameters, the system transforms rigid vibration absorption into flexible energy dissipation through controlled deformation, reducing peak force transmission to the frame.

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If heavy structures are used to absorb vibrations, then vibration absorption is improved, but fuel consumption and tire wear increase

Engineering Contradiction:
Improvevibration absorptionVSAvoidfuel consumption
Core Design Contradiction:
Stability of the object's compositionVSUse of energy by moving object

Solution Approach 1:

The ring bodies function as flexible protective elements with thin-walled structures that absorb vibrations through elastic deformation rather than mass. This flexible shell approach provides vibration damping without the weight penalty of traditional heavy rigid structures, reducing rotational inertia and overall vehicle mass.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The protection assembly combines materials with different properties - the ring bodies use elastic materials optimized for energy absorption, while the containment structure provides rigid support. This composite approach achieves vibration absorption performance without requiring uniformly heavy construction throughout the entire vehicle structure.

Inventive Principle:
Principle #40Composite materials

3Strength

If rigid protection structures are used, then impact protection is improved, but vehicle weight increases

Engineering Contradiction:
Improveimpact protectionVSAvoidvehicle weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The ring bodies are designed to dynamically respond to impact forces through elastic deformation, transitioning from a static rigid structure to a dynamic energy-absorbing system. During normal operation, the ring bodies remain flexible and lightweight, but during impact events, they deform to absorb energy, providing strength only when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The ring bodies are pre-positioned around the frame perimeter in a contained configuration, creating a cushioning barrier before impacts occur. This beforehand cushioning allows the use of lighter materials compared to fully rigid structures, as the energy absorption function is prepared in advance through the elastic properties of the ring bodies rather than requiring massive permanent reinforcement.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
