Rotatable Display Stand With Hollow Shaft Cable Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack the ability to adjust the rotation angle of the stand, allow or limit rotation based on user needs, stabilize cables, reduce electromagnetic interference from batteries, and improve torsional and bending stiffness.
Innovation Solution
A display device with a rotatable stand that includes a shaft fixed to the stand and coupled to a bracket, allowing for adjustable rotation, a hollow shaft for cable stability, and features that reduce electromagnetic interference and enhance stiffness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stand is made rotatable to allow angle adjustment, then the adaptability and ease of operation are improved, but the structural stability and reliability deteriorate
Solution Approach 1:
The stand incorporates a rotatable joint mechanism that allows dynamic adjustment of the rotation angle between the stand and display panel, enabling the structure to transition from a fixed to a movable configuration. This dynamic capability provides angle adjustment flexibility while maintaining structural integrity through controlled mechanical connections.
2Ease of operation
If the shaft is made hollow to stabilize cables, then the ease of operation and cable management are improved, but the torsional stiffness and structural strength worsen
Solution Approach 1:
The shaft is designed as a hollow structure with cables nested inside its interior cavity. This nesting arrangement allows cables to be routed through the shaft's hollow space, protecting them and organizing them neatly while maintaining the shaft's overall structural form and strength.
Solution Approach 2:
The shaft may be constructed using composite material structures or reinforced hollow designs that maintain torsional stiffness despite the hollow interior. This allows the shaft to provide cable routing pathways while preserving sufficient structural strength for supporting the display assembly.
3Object-generated harmful factors
If the stand structure is simplified to reduce electromagnetic interference, then the harmful factors are reduced, but the manufacturing precision and structural complexity worsen
Solution Approach 1:
The battery is extracted and positioned separately within the base structure, away from the display panel and critical electronic components. This spatial separation removes the source of electromagnetic interference from proximity to sensitive areas, reducing electromagnetic interference while maintaining a relatively simple overall structure.
