Notebook Frame Isolating Internal Components from External Stress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Notebook computer frames need to be rugged to withstand shocks and flexure, facilitate fluid drainage, and allow easy replacement of internal components like hard disk drives, while accommodating various housings and supporting planar computer cards without transferring external stress to them.
Innovation Solution
A unitary computer frame with a parallelepiped shape, featuring a battery enclosure, solid bay and disk drive plates, a grid structure, and hollow drain tubes, along with a base and keyboard bezel assembly that snap into place, isolating internal components from external stress and allowing liquid drainage and easy access for component replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the frame is made rugged to withstand shocks and flexure, then the strength and reliability are improved, but the internal components may be subjected to external stress and damage
Solution Approach 1:
The frame is divided into distinct functional zones: a rugged outer frame structure for strength, internal support plates (bay plate, disk drive plate, support plate) for component mounting, and isolated card supports for planar cards. This segmentation allows the outer frame to be strong while internal components are protected on separate supported structures.
Solution Approach 2:
Multiple intermediary support structures are introduced between the outer frame and internal components: bay plate, disk drive plate, support plate, and card supports. These intermediaries distribute and isolate external stresses, preventing direct transmission to sensitive components like hard disk drives and planar cards.
2Reliability
If the frame structure is made solid and enclosed, then the protection and reliability are improved, but the fluid drainage capability deteriorates
Solution Approach 1:
The frame structure implements local quality by having solid enclosed sections (battery enclosure, bay plate, disk drive plate) for protection in critical areas, while incorporating localized open structures (grid structure, vent holes in battery enclosure, cooling air opening in disk drive plate) specifically positioned for fluid drainage and ventilation functions.
3Stability of the object's composition
If the frame is designed with fixed internal components, then the structural stability is improved, but the ease of replacing components deteriorates
Solution Approach 1:
The frame is segmented into modular components: battery enclosure, bay plate, disk drive plate, support plate, and card supports. Each can be independently accessed and replaced while maintaining the overall structural stability of the frame, enabling easy repair without disassembling the entire structure.
4Adaptability or versatility
If the frame accommodates various housings and components, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The frame employs universal support structures (rails, support plates, bay plate) that can accommodate multiple types of components including hard disk drives, planar cards, and various housings. These multi-functional elements reduce overall complexity by using standardized mounting mechanisms rather than custom structures for each component type.

AI summary
A unitary magnesium frame for a notebook computer includes a planar card support that isolates the planar card from external stresses applied to a base cover assembly that is engaged with the frame. A keyboard bezel assembly can cover the frame opposite to the base cover assembly. Various component-supporting structures of the frame are disclosed.
