Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall-mounting systems for flat-screen displays lack a stable and adjustable mechanism to securely tilt electronic displays without requiring additional user input or tools, particularly for accommodating a range of weights and sizes.
Innovation Solution
A spring-based counterbalancing device with an eccentric gear mechanism that allows for easy manual adjustment of the vertical tilt angle of electronic displays, using a tension spring and adjustment screw to provide a counterbalancing force and friction at the pivot point, enabling secure and stable tilting without additional user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring-based counterbalancing device is added to provide stable tilt orientation, then the stability and durability of the tilt mechanism is improved, but the device complexity increases
Solution Approach 1:
The tension spring is integrated within the existing pivot point structure of the mounting mechanism. The spring's ends are attached to the bracket and the main fixing plate, nesting the counterbalancing function within the existing structural framework rather than adding a separate external mechanism.
Solution Approach 2:
The tension spring is pre-configured to provide counterbalancing force before the display is even mounted. The spring's tension is adjusted via the adjustment screw to pre-establish the desired tilt orientation, so that when the display is mounted, the counterbalancing action is already in place and requires no additional user input.
2Adaptability or versatility
If an adjustment screw is used to modify spring tension for different display weights, then the adaptability to different weights and sizes is improved, but the ease of operation decreases due to requiring screw adjustment
Solution Approach 1:
The adjustment screw is integrated into the mounting process itself. When users tighten or loosen the mounting screw to secure their display, they simultaneously adjust the spring tension to match their specific display's weight. The single screw serves dual functions: securing the display and calibrating the counterbalancing force.
Solution Approach 2:
The adjustment screw performs multiple functions: it secures the display bracket to the display, adjusts the tension spring's pre-tension, and sets the counterbalancing force for the specific display weight. This multi-functional design eliminates the need for separate adjustment mechanisms for different display weights.
3Device complexity
If friction at the pivot point is used alone to hold tilt position, then the device complexity is low, but the stability and durability are insufficient
Solution Approach 1:
The invention merges two mechanisms: the friction at the pivot point and the spring-based counterbalancing force. The tension spring provides a consistent counterbalancing force that works together with the friction at the pivot point, creating a combined system where both mechanisms support each other to hold the tilt position securely.
Solution Approach 2:
The tension spring acts as a counterweight mechanism, providing an opposing force to the display's weight. This counterbalancing force reduces the load on the pivot point friction, allowing the friction to maintain the tilt position more effectively without being overloaded, thereby improving both stability and durability.

Function Achieved in This Case
The solution provides a durable and adjustable mechanism that securely holds electronic displays in various tilt orientations, accommodating different weights and sizes with minimal effort, ensuring stability and ease of use by allowing manual adjustment of the tilt angle without additional tools.
Implementation Method 1
a tension spring comprising a lower end coupled to the main fixing plate, and an upper end coupled to the locking shaft of the eccentric gear, such that the tension spring retains a vertical-tilt orientation of the display-mounting bracket relative to the main fixing plate
Implementation Method 2
an adjustment screw coupled to the lower end of the tension spring, wherein rotation of the adjustment screw expands or compresses the tension spring
Implementation Method 3
the invention of the disclosure enhances the durability of the tilt mechanism and mount in general, as it provides a counterbalancing force in addition to friction that may be present at a pivot point of the vertical-tilt mechanism
