Portable Computer Latch Mechanism for Secure Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable computers with screw-secured housings are cumbersome for frequent interior access, and externally mounted batteries are aesthetically unpleasing and do not address interior access issues.
Innovation Solution
A portable computer with a sliding rack latch structure that engages a battery and access panel, using magnets and hooks for secure storage and access, with an optional lock to enhance security by preventing the latch mechanism's operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screw-secured housings are used, then structural strength is improved, but ease of operation deteriorates due to cumbersome disassembly for frequent access
Solution Approach 1:
The housing is divided into separate panels (access panel, battery compartment) that can be independently removed from the main housing body. This segmentation allows users to access interior components without disassembling the entire housing structure, resolving the contradiction between maintaining structural integrity and enabling easy access.
Solution Approach 2:
The patent introduces a dynamic latch mechanism with movable lever and rack components that transition between locked and unlocked states. This dynamic system replaces static screw connections, allowing the housing to switch between a secure closed state and an easily accessible open state, thereby improving ease of operation while maintaining strength when closed.
2Ease of operation
If externally mounted batteries are used, then ease of operation is improved for battery replacement, but appearance deteriorates due to unsightly bulge
Solution Approach 1:
The battery compartment is designed as a nested structure that fits within the housing contours. The battery can be independently accessed and removed through a dedicated compartment without external protrusion, maintaining the aesthetic appearance of the housing while preserving easy battery replacement capability.
Solution Approach 2:
The battery is extracted as a separate, independently accessible component through its own compartment with dedicated latch mechanism. This extraction allows the battery to be removed without affecting the main housing structure or creating external bulges, resolving the appearance issue while maintaining operational ease.
3Ease of operation
If simple latch mechanism is used, then ease of operation is improved, but reliability deteriorates due to insufficient security against unauthorized access
Solution Approach 1:
The patent merges multiple security functions into a single integrated latch mechanism: the lever provides user-friendly actuation, the rack delivers precise engagement, magnets provide continuous holding force, and hooks offer mechanical interlocking. This combination maintains ease of operation through the simple lever interface while achieving high reliability through the multi-layered security approach.
Solution Approach 2:
The latch mechanism combines different physical principles and material properties: magnetic forces from magnets, mechanical strength from metal hooks and rack, and user interface from the lever. This composite approach creates a security system that is both easy to operate legitimately and highly reliable against unauthorized access.
4Reliability
If multiple security features are added, then reliability is improved, but device complexity increases
Solution Approach 1:
The latch mechanism is designed as a universal system where a single lever operation controls multiple security features simultaneously. The lever actuates the rack, which engages with both magnets and hooks, providing multi-layered security through one integrated mechanism rather than separate controls for each feature, thereby limiting complexity increase.
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
Provides aesthetically pleasing and secure battery storage while allowing easy interior access without disassembly, enhancing user convenience and security by preventing unauthorized access to internal components.
Implementation Method 1
Magnets may help to hold the access panel in place
Implementation Method 2
The lock may prevent opening of the lever and thereby prevent the rack from moving
Implementation Method 3
Movement of the rack helps to disengage the access panel from the magnets

AI summary
A portable computer is provided that has a housing. A battery may be contained within the housing. The housing may have panels such as a fixed housing panel and a removable access panel. A lever actuated latching mechanism may be used to lock the removable access panel and the battery within the portable computer. A lock may be used to block movement of the lever and thereby prevent access to the interior of the computer. Magnetic elements may be used to facilitate operation of the lever and to hold the access panel in place. The latch mechanism may provide mechanical advantage when disengaging the magnets that hold the access panel.
