Two-Degree Display Mounting Assembly with Pivoting Stops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display panel mounting systems in vehicles, such as tractors, only allow for adjustment about a single axis, limiting flexibility and adaptability for different operators.
Innovation Solution
A mounting assembly with a dome-shaped lower and upper bearing member and a carrier member that allows for two degrees of freedom movement, utilizing stops and apertures to control pivoting, and a bolt and locknut system for secure positioning without hardware loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display panel mounting allows adjustment about a single axis, then the structure is simple, but the adaptability for different operators is limited
Solution Approach 1:
The mounting structure is divided into multiple functional segments: a pivot assembly for vertical angle adjustment, a horizontal adjustment mechanism for lateral movement, and a clamp mechanism for securing the display. Each segment handles one degree of freedom, allowing independent adjustment while maintaining overall structural coherence.
Solution Approach 2:
The invention transitions from single-axis adjustment to multi-axis adjustment by adding horizontal movement capability to the traditional vertical pivot mechanism. This creates a two-dimensional adjustment plane, enabling the display to move both vertically and horizontally to accommodate different operator positions and preferences.
2Ease of operation
If a mounting system allows significant movement, then the ease of operation improves, but the risk of hardware loosening increases
Solution Approach 1:
The clamp mechanism features a self-tightening design where the clamping force increases automatically as the display panel is inserted and adjusted. The friction-based grip maintains position during movement, and the spring-loaded or cam-actuated mechanism ensures consistent clamping pressure without requiring periodic manual tightening.
Solution Approach 2:
The mounting system uses dynamic friction control to balance ease of movement with security. During adjustment, reduced friction allows smooth movement, while during operation, increased friction through the clamp mechanism maintains stable positioning. The system transitions between these states based on operational phase.

AI summary
A display panel mounting assembly includes a dome-shaped lower bearing member on a support member, an upper bearing member, and a carrier member attached to the display panel and held between the upper and lower bearing members. The lower bearing member has a central bore and a pair of stops projecting from opposite sides of the bore. The carrier member has a opening which receives the stops. A stop post projects from the support member adjacent the bearing member. An aperture which receives the post is formed in the carrier spaced apart from the opening. The opening and the tabs cooperating to control pivoting of the carrier member with respect to the support member in one degree of freedom. The aperture and the post cooperate to control pivoting of the carrier member in a second degree of freedom.
