Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with rotatable displays are vulnerable to damage from impact forces when in extended configurations due to the lack of protection in existing coupling mechanisms.
Innovation Solution
A resilient coupling mechanism assembly that provides additional support and rigidity by incorporating a resilient member, a first member with a cavity, and a second member, which together absorb and distribute impact forces, reducing stress on the device when it is in an extended position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotatable coupling mechanism is used to allow display rotation, then the device achieves extended configurations and versatility, but the device becomes vulnerable to impact forces and damage
Solution Approach 1:
The resilient member (spring) is pre-installed in the coupling mechanism to provide cushioning before impact occurs. When impact forces are applied during extended configurations, the spring absorbs and dissipates the energy, protecting the display and internal components from damage while maintaining the rotatable functionality
2Area of moving object
If the device is configured in extended position, then the display area and functionality are increased, but the moment of force during impacts increases causing greater stress
Solution Approach 1:
The spring mechanism is pre-positioned in the coupling assembly to provide elastic cushioning before impact occurs. When the device is dropped or subjected to impact forces in extended configuration, the spring compresses to absorb the impact energy, significantly reducing the moment of force and stress transmitted to the display and internal components
3Ease of operation
If existing coupling mechanisms are used, then the device achieves rotatable functionality, but no protection is provided against impact forces
Solution Approach 1:
The resilient spring member is integrated into the coupling mechanism beforehand to provide protective cushioning. The spring absorbs and dissipates impact forces while allowing the rotatable movement to function normally, thus protecting the device against impact forces without compromising ease of operation
Solution Approach 2:
The spring acts as an intermediary element between the coupling components, mediating the transmission of forces. It allows rotational movement while providing elastic resistance to impact forces, protecting the display and internal components from direct exposure to harmful impact forces

Function Achieved in This Case
The resilient coupling mechanism decreases the moment of force experienced by the device during impacts, thereby reducing stress and damage to the components, enhancing the device's durability and functionality in extended configurations.
