Foldable Display Stand With Dual-Rod Locking for Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stands for display apparatus in recreational vehicles are fixedly connected and do not allow for easy adjustment of viewing angles, failing to meet user requirements for versatile viewing positions.
Innovation Solution
A stand with a rotating arm mechanism that includes a fixing plate, mounting plate, and a rotatable arm, allowing the stand to switch between folded and unfolded states, with a locking apparatus to secure the position and a dual-rod locking structure for stability, enabling adjustable viewing angles and secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional stand is directly and fixedly connected to a wall, then the structure is simple and stable, but the viewing angle cannot be adjusted
Solution Approach 1:
The stand is divided into multiple segments: a fixed mounting plate connected to the wall, a rotatable arm with multiple sections, and a display mounting plate. This segmentation allows the stand to transition from a simple fixed structure to an adjustable multi-position structure, resolving the contradiction between adaptability and complexity by enabling angle adjustment through modular components.
Solution Approach 2:
The stand incorporates a rotatable arm that can dynamically change its angle and position. The arm includes a first arm section and a second arm section that can rotate relative to each other, allowing the display apparatus to be positioned at different viewing angles. This dynamic capability provides adaptability while maintaining a relatively simple overall structure through controlled movement rather than complex mechanical adjustments.
2Adaptability or versatility
If a rotatable arm mechanism is added to allow angle adjustment, then viewing angle adaptability is improved, but the structure becomes more complex
Solution Approach 1:
The locking mechanism is designed to automatically engage and lock the rotatable arm at desired positions without requiring additional actuators or complex control systems. The self-service locking feature ensures reliability by providing automatic position fixation, while the relatively simple locking structure avoids adding excessive complexity to the overall system.
3Reliability
If a locking apparatus is added to secure the position, then stability is improved, but the device complexity increases
Solution Approach 1:
The locking function is extracted as a separate, dedicated mechanism rather than being integrated into the rotatable arm structure itself. This extraction allows the locking apparatus to be optimized for reliability while keeping the overall stand structure relatively simple. The locking mechanism operates independently to secure the display apparatus at fixed positions without complicating the primary support function.
