Stabilising Device for Portable Computing Rotation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable computing devices are cumbersome and unwieldy when rotated, posing a risk of dropping due to lack of effective rotational force resistance, and existing protective cases and grips are bulky and inefficient.
Innovation Solution
A stabilising device with a rotatable base plate, finger support member, and spacer elements that allow users to securely hold and rotate the device by inserting fingers between the base plate and finger support member, providing control against rotational and downward forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a user holds a portable computing device in one hand while moving about, then the device can be carried portably, but it becomes unwieldy to manipulate and rotate the device
Solution Approach 1:
The stabilising device acts as an intermediary mechanism between the user's hand and the portable computing device. It provides a structural framework with finger support members that mediate the interaction forces, allowing the user to securely hold and rotate the device without direct manual gripping alone
2Reliability
If existing protective cases, rigid carry handles, grips or straps are provided for portable computing devices, then protective coverage is improved, but the device becomes bulky and cumbersome
Solution Approach 1:
The stabilising device is segmented into distinct functional components: a base plate for mounting on the device, finger support members for user interaction, and spacer elements for structural integrity. This segmentation allows each component to be optimized for its specific function while maintaining overall compactness
Solution Approach 2:
The finger support members are designed to be movable rather than fixed, allowing them to adjust between a closed position (flush with base plate) and an open position (spaced from base plate). This dynamic capability provides adaptability for different usage scenarios while maintaining a sleek profile when not in use
3Reliability
If existing protective cases and grips are used, then some protection is provided, but they do not allow efficient resistance against rotational force
Solution Approach 1:
The stabilising device employs a composite structural design combining rigid elements (base plate, spacer elements) with flexible/movable elements (finger support members). This composite approach provides both protective rigidity and the mechanical advantage needed to resist rotational forces through lever arms and distributed force paths
