Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the normal impact absorption device (cellular energy-absorbing structure) and the tangential impact absorption device (clamping device with collapsible body) into a single integrated system. The cellular structure is connected to the shell through clamping devices, allowing both normal and tangential impact components to be absorbed synergistically through coordinated deformation of both devices, resolving the issue of separate devices not cooperating.

Inventive Principle:

Core Design Contradiction:

Loss of energyVSObject-affected harmful factors

Solution Approach 1:

The patent replaces traditional polymeric foam liners with a cellular energy-absorbing structure composed of interconnected open-cells. This porous structure absorbs impact energy through controlled deformation and collapse of the cellular architecture, achieving effective energy absorption while being more environmentally friendly than conventional foams.

Inventive Principle:

Core Design Contradiction:

Loss of energyVSStability of the object's composition

Solution Approach 1:

The patent employs a clamping device with a collapsible body that can dynamically adapt its stiffness and deformation characteristics during impact. The collapsible body allows controlled relative movement between the cellular energy-absorbing structure and the shell, enabling the system to manage deformation in a coordinated manner that maintains overall structural integrity while absorbing impact energy.

Inventive Principle:
