Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laptop support devices fail to securely position a laptop on a user's lap, leading to sliding and unnatural user positions, which can cause discomfort and potential injury.
Innovation Solution
A laptop support device with a planar main body and a tension support strap that wraps around the user, combined with a backstop structure to prevent laptop sliding, allows for secure and comfortable laptop positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple planar structure is used to support the laptop, then the device complexity is reduced, but the laptop stability deteriorates due to sliding
Solution Approach 1:
The support device is segmented into distinct functional components: a planar main body for supporting the laptop, and a separate tension support strap for securing it. This segmentation allows each component to perform its specific function efficiently while keeping the overall device relatively simple.
Solution Approach 2:
The solution transitions from a two-dimensional planar surface to a three-dimensional securing mechanism by adding the tension support strap that wraps around the user's body. This adds a new dimension of stabilization through bodily anchoring, preventing laptop sliding without significantly increasing device complexity.
2Stability of the object's composition
If the tension support strap is attached at rear locations on the main body, then the laptop position stability is improved by preventing backward sliding, but the device complexity increases
Solution Approach 1:
Attachment locations are specifically positioned at the rear portion of the main body to provide localized stabilization where it is most needed - preventing backward sliding of the laptop. This targeted approach optimizes stability without requiring complex mechanisms throughout the entire device.
Solution Approach 2:
The tension support strap acts as an intermediary element between the main body and the user's body. It transfers and distributes forces, securing the laptop through the user's body as an anchor point, thereby simplifying the overall securing mechanism while maintaining stability.
3Stability of the object's composition
If the backstop structure extends upward from the rear edge, then the laptop sliding prevention is improved, but the device complexity increases
Solution Approach 1:
The backstop structure is positioned locally at the rear edge of the main body, providing targeted prevention of backward sliding. This localized feature addresses the specific problem of laptop sliding without requiring complex mechanisms across the entire device structure.
Solution Approach 2:
The backstop structure is integrated with the main body as a unified component, eliminating the need for separate complex securing mechanisms. This merging of functions reduces overall device complexity while maintaining effective laptop sliding prevention.
4Ease of operation
If the forward edge is curved, then the user comfort is improved by allowing natural posture, but the manufacturing precision requirements increase
Solution Approach 1:
The forward edge of the main body is curved rather than straight, creating a more ergonomic shape that accommodates natural user posture. This curvature improves comfort by distributing pressure more evenly and allowing the user's body to relax into a natural position, while remaining manufacturable with standard molding processes.

AI summary
A laptop support device defines a forward direction, a rearward direction, a rightward direction, a leftward direction, an upward direction, and a downward direction, and includes a main body shaped as a planar structure and comprising an upper surface that faces the upward direction and that is configured to hold a laptop computer, and a tension support strap configured to be attached to the main body that is configured to wrap around a user such that the tension support strap is tensioned between the main body and the user.
