Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Folding electronic devices experience stress concentration and potential damage to displays due to external impacts, such as drop impacts, leading to defects like disconnection of LED circuits or bright spots, which are not adequately addressed by existing technologies.
Innovation Solution
Incorporating a first plate with opening structures on its planar portions that are stretchable or compressible to disperse and absorb external impacts, preventing stress concentration on the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid plate structure is used to support the display, then structural strength is improved, but stress concentration occurs during external impacts causing display damage
Solution Approach 1:
The plate includes opening structures that create a porous or lattice configuration. This allows the plate to maintain structural strength while enabling deformation during impact, dispersing stress across multiple points rather than concentrating it at single locations, thereby preventing display damage.
Solution Approach 2:
The plate's structural parameters are changed by introducing opening structures with specific patterns, sizes, and distributions. These parameter modifications allow the plate to transition from a completely rigid structure to one that can elastically deform under impact while maintaining overall strength, thus resolving the contradiction between strength and stress concentration.
2Stability of the object's composition
If the plate is made completely rigid to prevent movement between housings, then housing stability is improved, but impact forces are transmitted directly to the display causing defects
Solution Approach 1:
The opening structures in the plate act as pre-designed cushioning elements that deform during impact to absorb energy before it reaches the display. This beforehand cushioning mechanism protects the display from direct impact forces while the plate's overall structure maintains housing stability.
Solution Approach 2:
The porous configuration of the plate with opening structures allows controlled deformation during impact, providing a compromise between maintaining housing stability and protecting the display. The openings enable energy absorption through structural deformation while the remaining material maintains overall stability.
3Object-affected harmful factors
If opening structures are added to the plate to absorb impact, then impact resistance is improved, but manufacturing complexity increases
Solution Approach 1:
The plate is segmented into multiple regions by the opening structures, creating a modular lattice pattern. This segmentation can be efficiently manufactured using modern techniques such as stamping, molding, or additive manufacturing, where the opening patterns can be integrated into the overall plate fabrication process rather than requiring separate assembly steps.
Solution Approach 2:
The opening structures serve multiple functions simultaneously: they reduce weight, provide impact absorption through deformation, and maintain structural strength. This multi-functionality means that a single manufacturing process creates a structure that achieves multiple goals, rather than requiring separate components for each function, thereby reducing overall manufacturing complexity.
