Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The issue of inadequate fixing strength between the shaft cover and base in foldable screen terminals, leading to warpage and deformation of the shaft cover when exposed, affects the aesthetic appearance and user experience.
Innovation Solution
A hook mechanism with swing arms and mounting parts that rotate between unfolded and folded locations, applying tensile force to the shaft cover, enhancing connection strength by mounting protrusions and balancing forces to prevent warpage and deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the shaft cover is fixedly connected to the base using screw or glue dispensing, then the connection is simple to implement, but the connection strength is insufficient causing warpage and deformation
Solution Approach 1:
The swing arm is designed to rotate between unfolded and folded locations, dynamically changing its position to provide tensile force when folded. This dynamic mechanism enhances connection strength only when needed (in folded state) while maintaining ease of manufacture through a relatively simple rotational joint design.
Solution Approach 2:
The swing arm acts as an intermediary component between the shaft cover and base. It transmits tensile force from the mounting parts to the shaft cover, strengthening the connection without requiring direct complex fixing between the shaft cover and base.
2Strength
If the swing arm is added with mounting parts to apply tensile force, then the connection strength is improved, but the device complexity increases
Solution Approach 1:
The swing arm serves multiple functions: it acts as a structural support, provides rotational movement capability, and when folded, applies tensile force through the mounting parts to strengthen the shaft cover connection. This multi-functionality justifies the added complexity by delivering multiple benefits from a single component.
Solution Approach 2:
The mounting parts utilize parameter changes in the swing arm's position (between unfolded and folded states) to control the application of tensile force. When folded, the mounting parts engage to provide maximum strength; when unfolded, they disengage to avoid interference. This parameter-based control optimizes the strength-to-complexity ratio.
3Stability of the object's composition
If the swing arm rotates to apply tensile force when folded, then the shaft cover stability is improved, but the ease of operation decreases
Solution Approach 1:
The swing arm mechanism is designed to automatically assume the folded position where it provides maximum stability to the shaft cover. The gravitational force and structural design encourage the swing arm to rest in the folded position, providing continuous stability without requiring active control or user intervention to maintain the stabilizing force.

AI summary
This application relates to a hook mechanism, a support apparatus, and an electronic device. The hook mechanism includes a shaft cover, a base, and swing arms, and a plurality of first mounting parts are disposed in the shaft cover. The base is fixedly disposed in the shaft cover. The swing arms are disposed at two ends of the shaft cover along a first direction, and a second mounting part is disposed on the swing arm. The swing arm is rotatably connected to the base, so that the swing arm can rotate between an unfolded location and a folded location; and when the swing arms are in the unfolded location, the first mounting part is separated from a corresponding second mounting part; or when the swing arms are in the folded location, the first mounting part is mounted to the corresponding second mounting part.
