Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security solutions for portable electronic devices, such as laptops and smartphones, fail to effectively secure thinner devices with smaller housings due to incompatible aperture sizes and lack of compact, robust locking mechanisms.
Innovation Solution
A security apparatus featuring a lock mechanism with a cam member and engagement mechanism, including a lock cylinder, cam follower, and plunger, which is designed to securely engage thinner devices through a smaller aperture, allowing for rotation and linear movement to lock and unlock the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lock mechanisms are used for portable electronic devices, then security protection is provided, but the devices become too thick and cannot lay flat on surfaces
Solution Approach 1:
The engagement mechanism is nested within the housing, with fingers that can be inserted into the aperture and a plunger that moves within the housing cavity. This nesting allows the locking mechanism to provide security protection while maintaining a thin device profile, as the components are contained within the existing device thickness rather than adding external bulk.
Solution Approach 2:
The lock mechanism transitions from a traditional external locking approach to an internal engagement system where fingers extend through the aperture into the device interior. This dimensional reconfiguration allows the locking action to occur within the device's internal space, eliminating the need for thick external lock housings while maintaining security functionality.
2Length of moving object
If existing security solutions are applied to thinner devices with smaller housings, then device portability is improved, but effective security engagement becomes difficult due to incompatible aperture sizes
Solution Approach 1:
The engagement mechanism is designed with fingers that can be inserted into the aperture and a plunger that engages with these fingers through the aperture. This universal design allows the same mechanism to work with different aperture sizes and configurations, making it adaptable to various thin device form factors while maintaining effective security engagement.
Solution Approach 2:
The lock mechanism focuses its engagement force locally at the aperture interface, with fingers that can be inserted into the aperture and a plunger that applies concentrated force to engage these fingers. This localized engagement approach allows effective security locking in the limited space of thin devices without requiring the entire mechanism to be miniaturized, thus improving adaptability to different aperture sizes.
3Length of stationary object
If a compact locking mechanism is implemented through the aperture, then device thickness is reduced, but the complexity of the engagement mechanism increases
Solution Approach 1:
The engagement mechanism is segmented into distinct functional components: fingers that can be inserted into the aperture, a plunger that moves within the housing, and a cam member that converts rotational motion to linear motion. This segmentation allows each component to perform its specific function efficiently within the constrained space, reducing overall complexity compared to a monolithic locking mechanism while maintaining the ability to provide secure engagement through the aperture.
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 solution provides a compact and secure locking system that effectively secures thinner portable electronic devices, ensuring they cannot be easily removed while allowing the device to lay flat on a surface without obstruction, offering comparable security to conventional laptop locks.
Implementation Method 1
The cam member is rotatable about a rotational axis. The cam follower is constrained to linear translation perpendicular to the rotational axis. As the cam member is rotated by the lock cylinder, the plunger pushes the first finger and the second finger apart from each other to engage the portable electronic device.

AI summary
A security apparatus for a portable electronic device having an aperture includes a lock mechanism having a lock cylinder and a cam member. The lock cylinder is configured to be rotated by a key. The cam member is coupled to the lock cylinder for rotation with the lock cylinder. The cam member has a slot. The security apparatus also includes an engagement mechanism having a first finger, a second finger, and a plunger. The first finger and the second finger are configured to be inserted into the aperture of the portable electronic device. The plunger is positioned between the first finger and the second finger and has a cam follower positioned within the slot of the cam member. As the cam member is rotated by the lock cylinder, the plunger pushes the first finger and the second finger apart from each other to engage the portable electronic device.
