Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display stands face challenges in securely supporting and adjusting larger displays due to increased weight, leading to difficulties in smooth height, angle, and distance adjustments.
Innovation Solution
A display device with a structure that includes an upper arm, a lower arm, a base, a joint, a first elastic member, a second elastic member, an inner bar, and an outer bar, allowing for the folding and unfolding of the display stand and minimizing deformation of support links by increasing their rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display size is increased, then the display area is improved, but the weight of the display increases making it difficult for the stand to securely support and adjust smoothly
Solution Approach 1:
The stand is divided into multiple segments (base, lower arm, upper arm, support link) that can move independently relative to each other. This segmentation allows the stand to support heavier displays by distributing the load across multiple joints and mechanical advantage points, enabling smooth adjustment despite increased weight.
Solution Approach 2:
The stand employs dynamic elements including elastic members (springs) that provide continuous adaptive support force, and foldable link mechanisms that allow the stand to adjust its configuration. This dynamic design enables the stand to accommodate varying display weights and positions, maintaining smooth adjustability even as display size and weight increase.
2Stability of the object's composition
If the stand structure is made more rigid to support heavier displays, then the support stability is improved, but the ease of folding and unfolding is reduced
Solution Approach 1:
The stand uses elastic members (springs) integrated into the foldable link mechanism to provide continuous support force during folding and unfolding operations. This dynamic element allows the structure to maintain rigidity and stability when extended while remaining flexible and easy to manipulate during folding operations, resolving the contradiction between stability and ease of operation.
Solution Approach 2:
The elastic members change their mechanical parameters (force, stiffness) based on the extension state of the stand. When the stand is folded, the elastic members are compressed and ready to provide support force; when extended, they provide continuous stabilizing force. This parameter change allows the same structure to be both easy to fold and stable when deployed.
3Strength
If the support link rigidity is increased to minimize deformation, then the structural stability is improved, but the device complexity increases
Solution Approach 1:
The support function is segmented across multiple components (base, lower arm, upper arm, support link with elastic members) rather than requiring a single overly complex rigid structure. Each segment can be optimized for its specific function, achieving overall structural stability without excessive complexity in any single component.
Solution Approach 2:
The support link employs composite construction combining rigid structural elements with elastic members (springs). This composite approach provides the necessary rigidity to minimize deformation under load while the elastic components absorb stress and simplify the overall structure compared to a purely rigid design.
