Adjustable-Flap Electronic Device Bag for Ergonomic Screen Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ergonomic solutions for laptops and tablets are cumbersome, complex, and difficult to set up in unconventional environments, failing to provide a healthy working posture regardless of the user's location.
Innovation Solution
A lightweight, portable bag with adjustable flaps and hinges allows for easy height adjustment of electronic devices, incorporating magnetic and mechanical connections for accessories, ensuring ergonomic positioning and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a laptop is placed on a work surface at proper height for keyboard use, then typing comfort is improved, but screen height becomes too low for healthy posture
Solution Approach 1:
The bag is divided into two functional flaps: a first flap that folds back to form a support surface for the laptop, and a second flap that can be positioned at different heights. This segmentation allows the keyboard to remain at proper height while the screen is elevated by the second flap, resolving the contradiction between typing comfort and screen height.
Solution Approach 2:
The solution introduces a vertical dimension by using the second flap to elevate the screen height independently from the keyboard position. Instead of moving the entire laptop, the system adds height in the vertical dimension through the adjustable flap structure, maintaining proper keyboard height while achieving ergonomic screen height.
2Object-affected harmful factors
If a support riser is used to raise laptop screen height, then screen viewing height is improved, but keyboard and touchpad become too high causing shoulder and arm strain
Solution Approach 1:
The bag structure separates the support functions into two distinct flaps: the first flap provides the base support surface, while the second flap specifically addresses screen height elevation. This segmentation allows independent optimization of keyboard height (maintained by first flap) and screen height (adjusted by second flap), avoiding the problem of raising both simultaneously.
3Object-affected harmful factors
If existing ergonomic lifting devices are used, then screen height adjustment is improved, but device complexity and portability are worsened
Solution Approach 1:
The bag serves multiple functions: it carries the laptop, provides ergonomic support, and enables height adjustment - all in a single portable unit. The flaps are integrated into the bag structure itself, eliminating the need for separate lifting devices. This multi-functionality reduces overall system complexity while maintaining screen height adjustment capability.
Solution Approach 2:
The flaps are designed to be dynamically adjustable through simple folding and positioning actions. The second flap can be positioned at different heights and angles to accommodate various users and situations. This dynamic adjustability is achieved through simple hinge and fold mechanisms rather than complex mechanical systems.
4Ease of operation
If a bag structure is designed to provide ergonomic support, then ease of use is improved, but manufacturing complexity increases
Solution Approach 1:
The ergonomic support structure is segmented into simple, discrete flap components that can be manufactured independently and assembled. Each flap is a simple geometric shape that folds into position, avoiding complex molded or machined parts. This segmentation simplifies manufacturing while maintaining the ergonomic functionality.
