Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional balancing mechanism with multiple components is used, then the apparatus can provide stable force balancing, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the adjusting device and trajectory profile element into a single integrated component that performs multiple functions: guiding the application frame's movement trajectory, providing force balancing through the spring system, and enabling adjustable positioning. This merging of functions reduces the number of separate components while maintaining the necessary balancing functionality.
Solution Approach 2:
The adjusting device with trajectory profile element serves multiple purposes simultaneously: it guides the movement path of the application frame, interfaces with the spring system for force balancing, and provides adjustable positioning capability. This multi-functionality eliminates the need for separate guiding mechanisms and adjusting devices, reducing overall device complexity.
2Adaptability or versatility
If a conventional balancing mechanism with standard orientation is used, then the apparatus provides sufficient adjustment range, but the occupied space increases
Solution Approach 1:
The patent introduces an oblique orientation for the adjusting device relative to the front and back walls, utilizing three-dimensional space more efficiently. By orienting the adjusting device at an angle rather than parallel to the walls, the apparatus achieves the required adjustment range while occupying less horizontal space, effectively using the vertical and depth dimensions to compensate.
Solution Approach 2:
The patent employs an asymmetric arrangement where the second spring system and adjusting device face each other at a single side only, creating an unbalanced configuration that optimizes space utilization. This asymmetric positioning allows the components to be compactly arranged in available space rather than requiring symmetric distribution, reducing the overall apparatus footprint.
3Stability of the object's composition
If symmetric arrangement of spring systems and adjusting device is used, then the apparatus provides balanced forces, but the construction complexity and cost increase
Solution Approach 1:
The patent deliberately uses an asymmetric configuration where the second spring system and adjusting device are positioned to face each other at only one side, rather than creating a symmetric arrangement. This asymmetric design maintains force balance functionality while significantly simplifying the construction and reducing the number of components needed, thereby lowering manufacturing complexity and cost.
4Manufacturing precision
If multiple trajectory profile elements and arms are used, then the apparatus provides precise movement control, but the device complexity and cost increase
Solution Approach 1:
The patent merges the trajectory profile element with the adjusting device into a single integrated component. This combined element provides precise movement control through its guided trajectory function while eliminating the need for separate trajectory guidance mechanisms, thereby reducing the total number of parts and simplifying the overall device construction.

AI summary
An apparatus comprising a wall frame and an application frame. The application frame is movable with respect to the wall frame. The apparatus includes a first spring system and a second spring system, which two spring systems are each coupled with the wall frame and the application frame to apply forces on the application frame. The first spring system has its opposite ends connected to the wall frame and the application frame respectively. The second spring system is at a first end connected to the wall frame and the second spring system is at a second end distant from the first end connected to an adjusting device which is coupled with the application frame. The adjusting device is arranged to vary an extension of the second spring system when the application frame moves with respect to the wall frame. The adjusting device includes a single trajectory profile element, and only a first arm and a second arm that are connected to each other at a first hinge. An end of the first arm distant from the first hinge is with a second hinge connected to the application frame. An end of the second arm distant from the first hinge is with a third hinge connected to the second spring system. The first hinge that joins the first arm and the second arm is movably connected to and guided by the single trajectory profile element.
