Deployable Anti-Fall Shell With Triggered Buffer Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-fall devices, such as soft silicone shells, provide limited protection for electronic equipment when they fall from high places, as they are designed primarily for shock absorption during transportation and not for high-impact falls from great heights.
Innovation Solution
An anti-fall device comprising a trigger mechanism and a deformable structure that is compressed and elastically deformed within a shell, which pops out and recovers to provide comprehensive buffering when triggered, exceeding the size of the protected article in all directions to absorb impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soft silicone shells are used for protection, then the device provides shock absorption during transportation, but the protection ability is limited when electronic equipment falls from high places
Solution Approach 1:
The protective shell transitions from a static structure to a dynamic one by incorporating a trigger mechanism that activates deformable structures only when needed. The shell remains compact during normal use but automatically deploys buffer structures upon detecting a fall event, providing enhanced protection only when required.
Solution Approach 2:
The deformable buffer structures are nested within the shell during normal operation, occupying minimal space. When triggered, these structures unfold or expand outward from the shell, transforming from a compact stored state to an extended protective state that exceeds the shell's outer dimensions.
2Reliability
If buffer structures are always extended to provide maximum protection, then the protection ability is enhanced, but the device size increases and portability is reduced
Solution Approach 1:
The buffer structures dynamically transition between a compressed stored state within the shell and an extended protective state during falls. This dynamic deployment allows the device to maintain a compact volume during normal use while providing extended protection when needed.
Solution Approach 2:
The deformable buffer structures are pre-positioned within the shell in a compressed state, ready for rapid deployment. When a fall is detected, they quickly expand to their protective configuration, providing immediate protection without requiring the device to maintain a large volume throughout use.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively reduces the probability of damage to protected articles by providing extensive buffering and support in multiple directions during falls, enhancing protection beyond traditional shock absorption.
Implementation Method 1
a deformable structure and a trigger mechanism, wherein the deformable structure is connected with the trigger mechanism and is set to be compressed and elastically deformed when it is located in the shell

AI summary
An embodiment of the present application discloses an anti-fall device including a trigger mechanism, a deformable structure and a shell. The deformable structure is connected with the trigger mechanism and is set to be compressed and elastically deformed when located in the shell. The trigger mechanism is set in the shell and is configured to drive the deformable structure to move in a direction away from the trigger mechanism, so that the deformable structure pops out of the shell and recovers to a natural state from a compressed state.
