Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The quality of form converting for flexible screens is poor due to shape changes, leading to unstable viewing experiences and increased eye fatigue, especially with large-screen displays where users need to switch between curved and flat surfaces.
Innovation Solution
A form converting mechanism connected to the back of the flexible screen body, comprising a linkage of connecting members that allow for stable shape changes between flat and curved states, using pivotal structures and external forces to maintain form stability and prevent spontaneous return to the flat state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible screen body is used to enable form changes between curved and flat surfaces, then adaptability is improved, but form stability deteriorates due to shape changes after each conversion
Solution Approach 1:
The patent applies the dynamics principle by introducing a form converting mechanism with multiple connecting members that can dynamically adjust the screen body between curved and flat states. The mechanism includes a first connecting member with a first pivotal portion, a second connecting member with a second pivotal portion, a third connecting member connecting both pivotal portions, and a fourth connecting member connecting inner ends, allowing controlled dynamic transformation while maintaining stability in each state
Solution Approach 2:
The patent applies segmentation by dividing the form converting mechanism into multiple independent connecting members (first, second, third, and fourth connecting members) that work together through pivotal connections. This segmentation allows each member to contribute to the overall form conversion while maintaining individual control, improving both adaptability and stability
2Adaptability or versatility
If the distance between outer ends of connecting members changes during form conversion, then form adaptability is improved, but conversion quality deteriorates due to unstable transitions
Solution Approach 1:
The patent uses dynamics by designing the connecting members with pivotal portions that enable smooth, controlled movement during form conversion. The third connecting member connects the first and second pivotal portions, allowing the distance between outer ends to change in a controlled manner, ensuring stable transitions and high conversion quality
Solution Approach 2:
The patent applies the intermediary principle by introducing the third connecting member as a mediator between the first and second pivotal portions. This intermediary component ensures that the distance change between outer ends during form conversion is controlled and stable, improving conversion quality
