Backpack Collapsible Support Board for Mobile Device Posture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backpack designs for mobile device users do not adequately address the issue of maintaining proper posture during device use, leading to health issues such as 'Forward Head Posture Syndrome' and increased risk of chronic diseases like herniated discs and short-sightedness, as they fail to provide stable and convenient support for mobile devices.
Innovation Solution
A backpack with a collapsible support board that can be adjusted in length, rotation, and angle, allowing users to maintain a stable posture while using mobile devices and serving as a book stand, featuring a hinge and multiple positioning fix unit for secure adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile device is held with one or two hands for prolonged periods, then the device can be used, but hand and arm fatigue occurs leading to poor posture
Solution Approach 1:
The patent introduces a support board as an intermediary element between the user and the mobile device. This support board provides a stable surface for placing the device, eliminating the need to hold it with hands. The support board acts as a mediator that transfers the device weight to the backpack structure, thereby preventing hand and arm fatigue while maintaining device usability.
Solution Approach 2:
The support board is designed to be self-supporting through its connection to the backpack via hinge and positioning fix unit. Once deployed, the support board maintains itself in position without requiring continuous user intervention or effort. The mechanical structure (hinge + positioning fix unit) enables the support board to hold the device stably on its own, freeing the user's hands completely.
2Stability of the object's composition
If a support structure is added to the backpack, then posture stability is improved, but device complexity increases
Solution Approach 1:
The support structure is segmented into distinct functional components: the support board itself, the hinge mechanism for rotation, and the positioning fix unit for angle adjustment. This segmentation allows each component to perform its specific function independently while contributing to the overall stability. The modular nature of these segments makes the complex structure more manageable and easier to implement.
Solution Approach 2:
The support board incorporates dynamic elements including a hinge mechanism that allows rotation and a positioning fix unit that enables angle adjustment. These dynamic features allow the support structure to adapt to different usage scenarios and user preferences while maintaining stability. The ability to adjust the angle and position dynamically adds functionality without requiring an overly rigid and complex fixed structure.
3Adaptability or versatility
If the support board is made adjustable in length and angle, then versatility is improved, but manufacturing complexity increases
Solution Approach 1:
The support board employs a hinge mechanism that enables rotation and angle adjustment, providing dynamic adaptability for different usage positions. The positioning fix unit allows the board to be locked at various angles, offering versatility for different device types and user preferences. This dynamic design achieves high adaptability through relatively simple mechanical means compared to fully adjustable systems.
Solution Approach 2:
The support board's key parameter (angle) is made changeable through the positioning fix unit, which allows adjustment to multiple fixed angles. This parameter change capability provides versatility for different usage scenarios while maintaining manufacturing simplicity by using discrete angle positions rather than continuous adjustment mechanisms. The length is also adjustable through the hinge mechanism, further enhancing versatility without complex systems.
