Foldable Apparatus Rotating Shaft Base Prevents Main Body Abutment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable mobile phones often face issues where the two main bodies at the rotating shaft cannot be completely unfolded, and are prone to damage due to abutment and squeezing.
Innovation Solution
A foldable apparatus with a rotating shaft base and two main bodies, each equipped with a decorative member rotatably connected to the shaft and a housing slidably connected to the decorative member, allowing the housings to retract and rotate to a flush state when unfolded, and extend to cover gaps when folded, preventing abutment and accommodating a flexible display screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the two main bodies are unfolded completely, then the device achieves full extension, but the two main bodies abut against each other causing damage
Solution Approach 1:
The patent introduces a rotating shaft base as an intermediary component between the two main bodies. This rotating shaft base allows the main bodies to rotate relative to each other during unfolding, preventing direct abutment and contact that would cause damage. The rotating mechanism acts as a mediator that enables full extension while protecting the main bodies from collision.
Solution Approach 2:
The patent implements a dynamic unfolding mechanism where the two main bodies can rotate relative to each other around the rotating shaft base. Instead of a fixed linear unfolding path that leads to abutment, the dynamic rotational movement allows the main bodies to follow different trajectories, enabling complete unfolding without contact or damage to the main bodies.
2Volume of moving object
If the two main bodies are folded together, then the device achieves compact size, but the main bodies cannot be completely folded and remain damaged
Solution Approach 1:
The rotating shaft base enables dynamic folding motion where the two main bodies can rotate relative to each other. This rotational degree of freedom allows the main bodies to fold completely without being constrained by fixed geometric limitations, achieving compact size while preventing damage through controlled rotational movement rather than forced linear compression.
Solution Approach 2:
The patent divides the folding mechanism into segmented components: the rotating shaft base and the two independently rotatable main bodies. This segmentation allows each main body to rotate independently around the shaft base, enabling complete folding without mutual interference or damage, and achieving a more compact folded configuration.
3Ease of operation
If the display screen is folded, then the device achieves portability, but the display screen is prone to damage from squeezing
Solution Approach 1:
The dynamic rotational folding mechanism allows the display screen to be folded without direct compression or squeezing between the two main bodies. The rotational movement creates space and prevents the crushing forces that would damage the display, while still achieving the compact form factor needed for portability.
Solution Approach 2:
The rotating shaft base serves as a protective intermediary between the two main bodies during folding. It mediates the folding motion to prevent direct contact and squeezing of the display screen, allowing the device to be portable while protecting the vulnerable display component from damage.

AI summary
A foldable apparatus and an electronic device are provided in the present disclosure. The foldable apparatus includes a rotating shaft base and two main bodies disposed at two opposite sides of the rotating shaft base. Each main body is provided with a decorative member rotatably connected with the rotating shaft base and a housing slidably connected with the decorative member. The decorative member is disposed at an outer side of the housing and covers an edge of the housing close to the rotating shaft base. When the two main bodies are unfolded relative to each other, two housing respectively retract relative to two decorative members and respectively rotate along with the two decorative members to be close to the rotating shaft base, and the two decorative members rotate relative to the rotating shaft base to a flush state where a gap is defined between the two decorative members.
