Smart Bracelet Support Assembly for Expandable Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart bracelets have fixed-shaped display devices with limited screen size, failing to meet user demands for both miniaturization and larger viewing capabilities.
Innovation Solution
A support assembly for a smart bracelet display device featuring a deformable frame with slidably connected left and right support frames, allowing the screen to be expanded and retracted by unfolding and folding, supported by a bracket with receiving grooves and tooth portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the display device uses a fixed small size for miniaturization, then portability is improved, but the screen viewing size is reduced
Solution Approach 1:
The support assembly employs a deformable frame structure with sliding connections that allow the display device to dynamically change its configuration between folded and unfolded states. The left and right support frames can slide relative to each other along the bracket, enabling the screen to expand from a compact folded state to an extended viewing state, thus resolving the contradiction between miniaturization and large viewing area.
Solution Approach 2:
The support assembly is divided into multiple independent components: a bracket with receiving grooves, a left support frame with a first tooth portion, and a right support frame with a second tooth portion. These segmented parts can move independently relative to each other through the sliding and engaging mechanism, allowing the overall structure to transform from a compact to an expanded configuration while maintaining structural integrity.

If the display device is folded to achieve miniaturization, then portability is improved, but the structural complexity increases
Solution Approach 1:
The support assembly utilizes a nesting mechanism where the left and right support frames contain tooth portions that engage with receiving grooves on the bracket. When folded, the support frames nest within the bracket structure, creating a compact configuration. The tooth-groove engagement system allows the nested components to lock securely in both folded and unfolded positions, simplifying the overall structural complexity despite the transformative capability.

AI summary
A support assembly includes a left support frame, a right support frame, and a bracket. The left support frame and the right support frame are both slidably connected to the bracket. The bracket defines receiving grooves. The left support frame includes a first tooth portion. The right support frame includes a second tooth portion. When the support assembly is in a folded state, teeth of the first tooth portion and teeth of the second tooth portion are received in the receiving grooves to support the screen assembly in a retracted state; when the support assembly is in an unfolded state, the teeth of the first tooth portion and the teeth of the second tooth portion extend out of the receiving grooves to support the screen assembly in an extension state. A dial plate and a smart bracelet are further provided.
