Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotating mechanisms for electronic devices are overly complex and bulky, making them unsuitable for ultra-thin electronic products such as data cards, which require a compact and thin rotational connection.
Innovation Solution
A rotating mechanism comprising a base assembly, a rotator assembly, and a riveting gasket, where the rotator assembly is sheathed to the base assembly and restricted by a riveting gasket, allowing for axial rotation while maintaining a thin profile, utilizing elastomers with concave-convex structures for fixation and a roller for flexible rotation, resulting in a mechanism that fits within ultra-thin devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional rotating mechanism is used to connect ultra-thin data cards, then rotational connection functionality is achieved, but the mechanism becomes oversized and cannot fit within the ultra-thin device
Solution Approach 1:
The patent applies nesting by placing the rotator assembly inside the base assembly, with the rotator assembly including a rotator and elastomer that are contained within the base assembly's hollow structure. This nested configuration allows the rotating mechanism to achieve compact dimensions suitable for ultra-thin data cards while maintaining rotational functionality through the elastomer's elastic deformation capability
Solution Approach 2:
The patent uses an elastomer as a flexible component that can elastically deform to enable rotation. The elastomer's flexibility allows it to accommodate rotational movement within a compact space, providing the necessary rotational connection functionality without requiring a bulky mechanical structure, thus solving the contradiction between size and functionality
2Length of moving object
If existing rotating mechanisms are designed for rotational connection, then rotation capability is provided, but the axial thickness becomes too large for ultra-thin electronic products
Solution Approach 1:
The elastomer serves as a flexible element that enables rotation through elastic deformation rather than rigid mechanical movement. This allows the mechanism to achieve rotational functionality with minimal axial thickness, as the elastomer can deform within the confined space of the ultra-thin device without requiring additional axial room for traditional rotational components
Solution Approach 2:
The patent employs dynamic characteristics through the elastomer's ability to elastically deform during rotation. The elastomer dynamically adjusts its shape during rotational movement, allowing the mechanism to maintain rotational flexibility despite the constrained axial thickness. This dynamic behavior enables the ultra-thin mechanism to achieve the ease of operation needed for rotational connection
3Volume of moving object
If a compact rotating mechanism is designed to fit ultra-thin devices, then size is reduced, but the mechanism becomes overly simplified and lacks reliable fixation
Solution Approach 1:
The patent uses a composite structure combining rigid components (base assembly with hollow structure, rotator) and elastic components (elastomer). This composite design allows the mechanism to maintain compact size while the interaction between rigid and elastic materials provides reliable fixation through the concave-convex structure engagement, resolving the contradiction between size reduction and fixation reliability
Solution Approach 2:
The patent applies local quality by creating a concave-convex structure on the elastomer that engages with a corresponding structure on the rotator. This localized feature provides reliable fixation and rotation control without requiring the entire mechanism to be complex or large. The localized engagement structure ensures reliability while maintaining the overall compact design suitable for ultra-thin devices
