Laptop Elevation Device with Adjustable Legs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laptop computers experience overheating due to inadequate air circulation under the device, leading to user discomfort and potential damage, as the small rubber feet on the bottom do not provide sufficient airflow, and typing in a flat position strains wrists and hands.
Innovation Solution
A laptop elevation device that attaches to the bottom surface, featuring fold-up legs and a height adjustment mechanism, allowing for improved airflow and ergonomic positioning, with optional non-slip strips for secure placement on surfaces and a handle for carrying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If small rubber feet are used to provide air gap, then the laptop is supported, but the air circulation is insufficient causing overheating
Solution Approach 1:
The elevation device divides the support function into multiple components: a base that attaches to the laptop bottom, fold-up legs that create the air gap, and an arm with holes for height adjustment. This segmentation allows optimization of each component for its specific function while achieving overall improved airflow and temperature control.
Solution Approach 2:
The invention transitions from a two-dimensional flat laptop surface to a three-dimensional elevated structure by adding vertical height through fold-up legs. This dimensional change creates sufficient air gap underneath the laptop, enabling effective air circulation and heat dissipation while maintaining stability.
2Ease of operation
If laptop is kept in flat position, then the laptop is stable, but user experiences wrist and hand discomfort
Solution Approach 1:
The elevation device incorporates dynamic elements including fold-up legs that can be collapsed when not needed, and an arm with multiple hole positions that allows adjustment of the laptop angle. This dynamic design enables the laptop to transition between different positions (flat for stability, elevated for ergonomics) while maintaining stability at each position through proper engagement of the arm in hole slots.
3Ease of operation
If fold-up legs are added for elevation, then airflow is improved, but device complexity increases
Solution Approach 1:
The invention merges multiple functions into a single integrated device: the base attaches to the laptop, the fold-up legs provide elevation and airflow, the arm with holes enables height and angle adjustment, and the entire structure can be collapsed for portability. This merging of functions reduces the need for multiple separate accessories while achieving improved airflow and ergonomics.
Solution Approach 2:
The elevation device uses thin, flexible components including the fold-up legs and arm structure that can be easily collapsed and stored. This flexibility allows the device to transition from an extended functional state (providing airflow) to a compact storage state (reducing complexity and portability issues) without requiring complex mechanisms.
4Ease of operation
If height adjustment mechanism is added, then ergonomic positioning is improved, but manufacturing complexity increases
Solution Approach 1:
The arm features localized quality variations with holes positioned at specific intervals to provide discrete height and angle adjustment options. This local quality approach allows ergonomic customization without requiring complex continuous adjustment mechanisms, simplifying manufacturing while still providing multiple positioning options for different user needs.

AI summary
A laptop elevation device (1) that attaches to a bottom surface (13) of a laptop (12). Each laptop elevation device has a fold-up leg (2) pivotally or hingedly attached to a base (3). An arm (5) is pivotally attached to the base. When the laptop elevation device is in an open position, the arm may be folded downward to engage one of a plurality of holes (9) located on the leg, thereby locking the laptop elevation device at a desired height. The base may be built into a laptop or attached to the underside of an existing laptop using an attachment means (14). The leg may also have a layer of rubber (11) to prevent the leg from slipping while in use. A clip (11) located on the base locks the leg and arm in place while the laptop elevation device is in folded position. An additional feature of the laptop elevation device is one or more non-slip strips (20) that attach to the underside of a laptop to allow the front portion of the laptop to hang over the edge of a flat surface (22) while the laptop is in an elevated position. An alternative embodiment of the laptop elevation device provides a handle (17) for carrying the laptop computer.
