Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable mobile devices experience issues such as derailment of pivot, broken shaft, and bent track when the pivot cover touches the ground and absorbs an impact force, affecting the folding function and user experience.
Innovation Solution
A display panel with an impact-resistant structure featuring a gravity sensing assembly and telescopic assembly, which switches between contracted and elongated states upon impact, dispersing the impact force directly to the frame body, reducing deformation of the rotating assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pivot cover is only connected to the middle frame through the rotating assembly, then the rotating mechanism can achieve smooth folding motion, but the impact force will be transmitted to the rotating mechanism causing derailment of pivot, broken shaft, and bent track
Solution Approach 1:
The patent introduces an impact-resistant structure as an intermediary component between the pivot cover and the rotating assembly. This mediator absorbs and disperses impact forces before they reach the rotating mechanism, protecting the pivot, shaft, and track from damage while maintaining the smooth folding motion capability
Solution Approach 2:
The impact-resistant structure is pre-configured within the pivot cover to provide cushioning protection before impact occurs. The structure includes energy-absorbing components that are ready to activate upon impact, dispersing forces in advance to prevent damage to the rotating assembly
2Force
If the impact force is transmitted through the rotating assembly to the frame body, then the pivot cover can absorb impact, but the rotating assembly suffers deformation and damage
Solution Approach 1:
The patent converts the harmful impact force into beneficial energy absorption through the impact-resistant structure. The structure transforms the destructive force into controlled deformation of energy-absorbing materials, protecting the rotating assembly from direct damage while still allowing the pivot cover to absorb impact
3Object-affected harmful factors
If the rotating mechanism is forced by impact force, then the pivot cover absorbs the impact, but derailment of pivot, broken shaft, and bent track occur
Solution Approach 1:
The impact-resistant structure serves as a protective intermediary that intercepts impact forces before they can displace the pivot, shaft, or track from their proper alignments. This mediator maintains the precise manufacturing accuracy of the rotating assembly even when subjected to external impact forces
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 impact-resistant structure effectively disperses impact forces, enhancing the durability of the rotating assembly and improving user experience by reducing deformation and extending the lifespan of the folding mechanism.
Implementation Method 1
the gravity sensing assembly is used to drive the telescopic block into the elongated state while being forced by an external force
Implementation Method 2
the telescopic assembly comprises a telescopic block, and the telescopic block and the frame body are disposed opposite to each other
Data Source
AI summary
A display panel and a mobile terminal are disclosed. The display panel includes a pivot cover. An impact resistant structure is embedded in the pivot cover. The impact resistant structure includes a gravity sensing assembly and a telescopic assembly. The telescopic assembly includes a telescopic block. The impact resistant structure drives the telescopic block to switch between a contracted state and an elongated state through whether the gravity sensing assembly is forced by an external force, so that the telescopic block is switching between spaced from the frame body and abutted against the frame body, thereby making the impact resistant structure switch between a first state and a second state.
