Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reliability of hinge mechanisms in foldable electronic devices is compromised due to the risk of mechanical parts being misplaced or damaged during shocks or collisions, leading to structural instability and reduced overall device reliability.
Innovation Solution
A hinge mechanism design that includes a main shaft assembly, housing fastening brackets, and a support assembly with protrusions and grooves, allowing for horizontal positioning and reducing the risk of misplacement, even when the device is in an unfolded or closed state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hinge mechanism uses multiple mechanical parts in transmission connection to enable folding function, then the folding capability is achieved, but the reliability deteriorates due to misplacement risk during shock or collision
Solution Approach 1:
The patent applies preliminary anti-action by pre-designing groove-protrusion limiting structures between mechanical parts. These structures are positioned in advance to prevent misplacement during shock or collision, counteracting the potential harmful effects before they occur. The grooves and protrusions are specifically designed to restrict relative movement of the swing arm, support arm, and main shaft assembly during unexpected shocks, thereby maintaining structural stability while preserving folding functionality.
2Ease of operation
If the mechanical parts are connected through transmission connection to enable joint actions, then the folding function is implemented, but the risk of misplacement increases during shock events
Solution Approach 1:
The patent introduces groove-protrusion structures as intermediary limiting elements between the swing arm, support arm, and main shaft assembly. These intermediaries act as mechanical constraints that guide and restrict relative movement, preventing misplacement during shock events while still allowing the necessary folding motion. The grooves serve as mediators that maintain proper alignment and positioning of the connected mechanical parts throughout operation.
3Adaptability or versatility
If the hinge mechanism allows rotation of housing fastening brackets relative to the main shaft assembly, then the folding function is enabled, but horizontal displacement risk increases
Solution Approach 1:
The patent segments the rotation capability and positioning function into separate structural elements. The housing fastening brackets are designed to rotate relative to the main shaft assembly for folding operation, while groove-protrusion limiting structures are separately positioned to constrain horizontal displacement. This segmentation allows the rotation capability to function independently while the positioning stability is maintained by the limiting structures, resolving the contradiction between adaptability and stability.

AI summary
A hinge mechanism includes a base, a first housing fastening bracket, a second housing fastening bracket, and a support assembly. The support assembly includes a first support part, a second support part, and a third support part. The first support part is disposed at an end part of the first housing fastening bracket, and the first support part is provided with a first protrusion and a first groove. The second support part is disposed at an end part of the second housing fastening bracket, and the second support part is provided with a second protrusion and a second groove. The third support part is disposed at an end part of the base, and a fourth protrusion and a fourth groove are disposed on a side that is of the third support part and that is proximate to the second housing fastening bracket.
