Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the wall mount assembly is designed to be thin to fit inside residential walls, then the installation space requirement is improved, but the mechanical strength and load-bearing capacity deteriorate
Solution Approach 1:
The wall mount assembly is divided into multiple structural components including vertical support members, horizontal support members, and mounting plates distributed at different positions. This segmentation allows the thin profile to maintain strength through distributed load paths rather than requiring a single deep structural element
Solution Approach 2:
The patent transitions from a single-plane mounting structure to a three-dimensional distributed support system with members extending in multiple directions (vertical, horizontal, and depth). This dimensional expansion allows the thin assembly to achieve adequate load-bearing capacity through spatial distribution of support elements
2Ease of operation
If the wall mount assembly includes a swiveling mechanism for azimuth adjustment, then the viewing convenience is improved, but the device complexity increases
Solution Approach 1:
The swiveling mechanism enables the display mounting portion to dynamically adjust its azimuth angle while maintaining structural support. This dynamic capability allows the system to adapt to different viewing positions without requiring multiple fixed mounting configurations
Solution Approach 2:
The patent introduces a swiveling mechanism as an intermediary component between the fixed wall mount and the display. This intermediary element provides the necessary rotational freedom while maintaining a clear separation between the stationary mounting structure and the movable display portion
3Shape
If the wall mount assembly is positioned high on the wall above a fireplace, then the aesthetic appearance is improved, but the risk of overheating increases
Solution Approach 1:
The patent incorporates temperature sensors that continuously monitor the thermal environment around the display. This feedback mechanism allows the system to detect elevated temperatures and respond by adjusting the display position or activating cooling measures, creating a closed-loop safety system
Solution Approach 2:
The patent positions temperature sensors and thermal management components in advance to prevent overheating before it occurs. The system proactively monitors thermal conditions and can adjust display positioning or activate cooling measures before dangerous temperature levels are reached
4Extent of automation
If the wall mount assembly uses linear actuators for raising and lowering the display, then the automation level is improved, but the device complexity increases
Solution Approach 1:
The linear actuators are equipped with position sensors and control systems that enable them to automatically raise and lower the display to predetermined positions without continuous manual intervention. The system can autonomously navigate between stored position configurations and respond to simple user commands
5Adaptability or versatility
If the wall mount assembly is designed to accommodate various display weights, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The wall mount assembly employs universal mounting plates and adjustable support structures that can accommodate displays across a wide weight range. The same basic structural components and mounting mechanisms serve multiple weight classes, eliminating the need for completely different mounting systems
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case

Implementation Method 1
The force for lowering and raising the TV may be provided, for example, by linear actuators
Implementation Method 2
a swiveling mechanism may be included to provide for right-left swiveling with respect to the TV's vertical axis

AI summary
A TV wall mounting device includes a wall mount box with vertical supports, a display mount receiving a TV, and an extending/contracting portion between the box and the display mount. The extending/contracting portion has lower and upper arms rotatably attached to the wall mount with rear axles, a pair of linear actuators rotatably attached to the wall mount, a front portion that rises and lowers with action of the actuators, and a horizontally-swiveling portion that is raised and lowered with the front portion and is capable of rotating right-left with respect to the front portion. The display mount is attached to the horizontally-swiveling portion. Parallel operation of the linear actuators, wherein each actuator extends and retracts while keeping the same length as the other actuator, causes the display mount to go up and down. Differential operation of the actuators causes the display mount to rotate right and left.
