Notebook Display Hinge Rotation That Prevents Chassis Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems face challenges in smoothly rotating displays without damaging the chassis, as current designs either result in display rotation relative to support arms before they are fully open, leading to chassis engagement and potential damage, or require excessive force for rotation, making it difficult to switch between notebook and tablet modes.
Innovation Solution
A display rotation controlling apparatus with rotatably coupled support arms and a display featuring detent channels and resiliently biased detents that allow smooth rotation while preventing the display from engaging the chassis, ensuring the chassis remains secure and preventing damage during mode transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display is allowed to rotate smoothly and easily relative to the support arms, then the ease of operation is improved, but the display may rotate before the support arms are fully open, causing the display to engage the chassis and potentially damage it
Solution Approach 1:
The support arms are rotated to the open position first, establishing the correct sequence of operations. Only after the support arms are fully open is the display rotated relative to the support arms. This preliminary positioning of the support arms prevents the display from engaging the chassis during rotation.
Solution Approach 2:
The support arms serve as an intermediary mechanism between the chassis and the display. By rotating the support arms first to the open position, they create sufficient clearance and space for the display to be rotated without engaging the chassis, thus preventing potential damage.
2Reliability
If the force required to rotate the display relative to the support arm is increased to prevent rotation before support arms are open, then the reliability is improved, but the display becomes difficult to rotate
Solution Approach 1:
The support arms are rotated to the open position before the display is rotated relative to them. This preliminary action establishes the correct operational sequence, allowing the display to rotate smoothly without requiring excessive force, while still preventing chassis engagement.
Solution Approach 2:
The support arms act as an intermediary that, when positioned in the open state, enable smooth display rotation without requiring increased force. They mediate between the display and chassis, allowing easy rotation while maintaining reliability through proper sequencing rather than force.

Function Achieved in This Case
Enables seamless conversion between notebook and tablet modes without damaging the chassis, providing a user-friendly experience while maintaining structural integrity by controlling the display's rotation and securing mechanisms.
Implementation Method 1
a resilient member operable to bias the detent into the detent channel
Implementation Method 2
The rotational display coupler may then be rotated relative to the support arm such that the securing tooth is removed from the catch channel support arm coupling member

AI summary
A display rotation controlling apparatus includes a chassis base, a plurality of support arms rotatably coupled to the chassis base, at least one support arm including a display coupling member, and a display rotatably coupled to the support arms, the display including at least one support arm coupling member. The display coupling member and support arm coupling member are engaged in order to orient the display in a notebook mode and may be disengaged to orient the display in a tablet mode.
