Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable electronic devices face challenges in accurately controlling the angle and precision of the unfolded state, leading to potential overfolding or unevenness, which affects user experience and display quality.
Innovation Solution
A folding control mechanism is introduced, featuring a base, rotating assemblies, swing arms, housing fastening brackets, and stop blocks. This mechanism uses sliding grooves and stop blocks to precisely control the unfolding angle, preventing overfolding and ensuring evenness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a folding control mechanism without stop function is used, then the device has simpler structure, but the unfolding angle cannot be precisely controlled leading to overfolding or unevenness
Solution Approach 1:
A stop block is introduced as an intermediary component between the swing arm and housing fastening bracket. This stop block acts as a mediator to precisely limit the unfolding angle by providing a physical stop point, thereby achieving accurate angle control without requiring complex control systems or multiple components.
2Adaptability or versatility
If the swing arm has large relative movement range, then the device has greater flexibility, but the control precision of unfolded state deteriorates
Solution Approach 1:
The movement range of the swing arm is segmented into two distinct phases: a free movement phase that provides folding flexibility, and a controlled phase where the stop block engages to precisely limit the unfolding angle. This segmentation allows the mechanism to achieve both adaptability and precision by dividing the motion trajectory into functional zones.
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 mechanism effectively reduces relative movement between the arc arm and the installation plate, allowing for accurate control of the unfolding angle, thereby enhancing user experience and product competitiveness by preventing overfolding or unevenness.
