Solution Overview
Problem
Existing display support arm assemblies lack adjustable force mechanisms and effective rotational resistance, limiting user flexibility in positioning and securing displays.
Innovation Solution
The display support arm assembly incorporates a gas strut for vertical adjustment, torque elements for adjustable friction, and a washer-gasket system to resist unintended rotational movement, providing a customizable and stable mounting solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a gas strut is used to provide force throughout the vertical adjustment range, then the display can be easily positioned vertically, but the force provided cannot be adjusted to different weights
Solution Approach 1:
The patent applies dynamics by making the gas strut force adjustable rather than fixed. The rod coupled to the adaptor can be rotated to change the vertical position of the adaptor, which dynamically adjusts the force provided by the gas strut to match different display weights and positioning needs.
Solution Approach 2:
The patent implements parameter changes by allowing the user to adjust the force parameter of the gas strut through rotating the rod. This changes the physical state of the system from a fixed-force mechanism to an adjustable-force mechanism, enabling adaptation to different display weights and vertical positioning requirements.
2Reliability
If torque elements are added to provide adjustable friction force, then the display can be securely held at different positions, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the torque adjustment function into discrete torque elements that can be individually added or removed. This allows the friction force to be adjusted in steps rather than requiring a complex continuous adjustment mechanism, simplifying the overall device while maintaining reliability.
Solution Approach 2:
The patent implements parameter changes by allowing the friction force parameter to be adjusted through adding or removing torque elements. This changes the physical state of the system from a fixed-friction design to an adjustable-friction design, enabling secure holding at different positions while keeping the adjustment mechanism simple.
3Stability of the object's composition
If washers and gaskets are used to resist rotational movement, then the arm is securely fixed to the object, but unintended rotation may still occur
Solution Approach 1:
The patent implements parameter changes by allowing the rotational resistance parameter to be adjusted through adding or removing gaskets. This changes the physical state of the connection from a fixed-resistance design to an adjustable-resistance design, enabling the arm to be securely fixed while preventing unintended rotation through optimized friction control.
