Sensor-Activated Hinge Lock for Laptop Lid Closure Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices are prone to display damage due to objects lying on the cover during lid closure or from hard closures, which are often not covered by warranty policies.
Innovation Solution
A hinge lock apparatus that employs ultrasound spatial awareness systems or other sensors to detect objects on the housing and deploy a mechanism to prevent damage to the display during lid closure, while also allowing for controlled angular positions to enhance thermal efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lid is allowed to close freely, then the ease of operation is improved, but the display may be damaged by objects or hard closures
Solution Approach 1:
The hinge lock apparatus activates before the lid closes to detect objects on the keyboard and prevent damage by locking the hinge at a safe angle, allowing the lid to close freely when safe while preventing damage when objects are present
Solution Approach 2:
The hinge lock apparatus serves as an intermediary mechanism between the lid and keyboard, detecting objects and controlling hinge movement to prevent direct contact between the lid and objects, thereby protecting the display
2Reliability
If the hinge is locked to prevent display damage, then the reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The hinge lock apparatus dynamically adjusts the hinge locking state based on real-time detection of objects and closing speed, allowing free movement when safe and locking when danger is detected, rather than maintaining a fixed locked state
Solution Approach 2:
The system continuously monitors the closing process through sensors detecting objects and closing speed, providing feedback to the hinge lock control to adjust the locking state appropriately, ensuring both protection and operational ease
3Temperature
If the lid is restricted to controlled angular positions for thermal efficiency, then the thermal performance is improved, but the adaptability deteriorates
Solution Approach 1:
The hinge lock apparatus provides dynamic angular positioning that adapts to different operating conditions, restricting to thermal-efficient angles when needed while allowing full flexibility during normal operation, rather than fixing the lid at a single angle

AI summary
Hinge lock apparatus for electronic devices and related methods are disclosed. A system includes a first housing, a second housing, and a hinge to pivotally couple the first housing and the second housing. The hinge includes a hinge lock apparatus having a lock interface and an actuator movable relative to the lock interface between a first position to engage the lock interface to at least one of prevent or restrict rotation of the first housing relative to the second housing, and a second position to disengage the lock interface to enable rotation of the first housing relative to the second housing. Processor circuitry operates the actuator based on a detected condition of the first housing relative to the second housing.
