Deployable Laptop Riser With Arc Legs for Cooling and Portability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laptop risers fail to effectively dissipate heat and provide comfort due to inadequate ventilation and lack of portability, as they often require a fixed configuration that does not allow for easy angle adjustment or heat dissipation.
Innovation Solution
A laptop riser with deployable arc-shaped legs formed from a deformable plastic sheet that can be slid into position to elevate the laptop at an angle, incorporating vents for heat dissipation and a compact design for portability, using a flexible strap to deploy the legs and secure them in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the laptop riser uses a fixed configuration, then it provides stable support, but it lacks portability and cannot be easily transported
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed configuration into a deployable structure. The riser includes legs that can be selectively deployed from a stowed position to a deployed position, allowing the device to adapt between a compact portable state and a stable support state. This dynamic transformation resolves the contradiction by making the structure movable rather than fixed.
Solution Approach 2:
The patent segments the riser into a base, deployable legs, and a laptop support surface. The legs can be independently deployed or stowed, allowing the structure to be divided into functional components that can be selectively positioned. This segmentation enables the riser to transition between compact and expanded configurations.
2Device complexity
If the laptop riser lacks ventilation structures, then it maintains a simple compact design, but it fails to dissipate heat effectively
Solution Approach 1:
The patent incorporates ventilation openings in the base and/or laptop support surface, creating a porous structure that allows air to pass through. These openings enable heat dissipation by facilitating airflow across the laptop's heat-generating components, resolving the contradiction by introducing functional porosity into the design.
Solution Approach 2:
The patent introduces air as an intermediary medium to transfer heat from the laptop. The ventilation structures channel air flow through the riser, using the air current as a mediator to carry heat away from the laptop, thereby improving thermal management without significantly complicating the overall design.
3Strength
If the laptop riser uses rigid support structures, then it provides stable elevation, but it cannot be folded into a compact configuration for transport
Solution Approach 1:
The patent applies dynamics by making the support structure deployable rather than permanently rigid. The legs can be extended to provide stable elevation when needed and folded back into the base when not in use, allowing the structure to dynamically adjust its configuration based on operational requirements.
Solution Approach 2:
The patent implements nesting by placing the deployable legs inside or against the base when not in use. The legs are stored within the confines of the base structure, allowing the entire riser to be compacted into a small portable form factor while maintaining the capability to extend into a stable elevated configuration when deployed.
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 effective heat dissipation, comfort through adjustable angle positioning, and portability, ensuring the laptop is kept cool and comfortable to use, while being easy to transport and store.
Implementation Method 1
The arcs deform slightly with the weight of a laptop to distribute the weight comfortably across a person's lap
Implementation Method 2
The arcs also form air channels which allow air to flow help to keep the laptop cool
Implementation Method 3
the structure elevating the laptop have vents or other structures to permit heat to flow from the laptop

AI summary
A portable riser for supporting a laptop computer or other article at an angle to a supporting surface. The riser includes a base and lid attached to each other by a double hinge. Arc shaped legs deploy form the riser when the lid is moved from a closed position to an deployed position a position where the lid rests against the opposite side of the base. The legs are formed by deforming a sheet of flexible material that lies between the base and a cover plate. The lid and the sheet of flexible material are coupled to each other so that when the lid is moved from the closed to the deployed position, the sheet of material is deployed.
