Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable assemblies for electronic devices face challenges in ensuring accurate fitting dimensions and efficient installation of arc-shaped slides, leading to low installation efficiency and high adjustment requirements due to the need for precise processing and assembly of multiple components.
Innovation Solution
The foldable assembly design includes independent upper brackets and integrated lower brackets, with sliding parts and main swing arms, allowing for separate installation and adjustment of arc-shaped slides, enhancing fitting accuracy and reducing assembly time through simplified installation processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a folding structure is added to enable the electronic apparatus to fold, then portability and space-saving are improved, but the structural complexity and manufacturing difficulty increase
Solution Approach 1:
The electronic apparatus is divided into multiple rigid bodies (first rigid body, second rigid body, third rigid body) connected by folding joints, allowing the structure to be segmented and folded while maintaining structural integrity of each segment
Solution Approach 2:
The folding structure allows the electronic apparatus to be nested into a compact configuration when folded, with the third rigid body positioned between the first and second rigid bodies, creating a nested arrangement that reduces overall volume
2Duration of action of stationary object
If the folding structure uses existing technology, then development time is reduced, but the folding durability is insufficient due to repeated folding causing disconnection
Solution Approach 1:
The folding joints are designed with dynamic characteristics that allow smooth repeated folding movements while maintaining connection integrity, enabling the structure to adapt to repeated folding cycles without disconnection
Solution Approach 2:
The folding joint design incorporates protective features that cushion and distribute stresses from repeated folding, preventing connection failure before it occurs by addressing stress concentration issues in advance
3Ease of manufacture
If the folding joint design is simplified, then manufacturing is easier, but the structural strength and resistance to folding-induced stress decrease
Solution Approach 1:
The folding joint design optimizes geometric parameters and material distribution to achieve adequate strength while maintaining manufacturing simplicity, balancing structural requirements with manufacturing constraints

AI summary
Disclosed are a foldable assembly of an electronic device and an electronic device. The electronic device may be a terminal product that includes a foldable flexible display, such as a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, a virtual reality device, a notebook computer, a super mobile personal computer, a netbook, or a personal digital assistant. Sliding parts are respectively disposed on two sides of a rotating shaft part, the sliding parts include an upper bracket and a lower bracket, and the upper bracket and the lower bracket can be enclosed to form an arc-shaped slide. A main swing arm is further disposed on the door plate, the door plate can rotate around the rotating shaft part and drive a fitting segment of the main swing arm to slide along the arc-shaped slide, and each upper bracket is an independent structure. During installation, each upper bracket is separately fastened to a corresponding lower bracket, and problems of low assembly efficiency of a sliding part and an inaccurate dimension of an arc-shaped slide can be simultaneously resolved.
