Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional angle adjustment lock is used to connect adjacent display units, then the display units can be connected and the angle can be adjusted, but the adjustment process is complex and difficult to operate
Solution Approach 1:
The adjustment mechanism is segmented into independent functional components: an operating member for user input, a transmission member (crank mechanism) for motion conversion, and guide portions for constrained movement. This segmentation allows each component to perform its specific function efficiently, simplifying the overall operation while maintaining adjustability
Solution Approach 2:
The lock base is designed with dynamic characteristics, allowing it to rotate and adjust the included angle between display units. The operating member can be manually rotated to dynamically change the angle, and the lock base moves along an arc trajectory defined by the guide portions, enabling smooth and easy angle adjustment
2Productivity
If a traditional angle adjustment lock is used, then the display units can be connected, but the adjustment of included angle requires significant effort and time
Solution Approach 1:
The guide portions are designed with curved arc trajectories that guide the lock base movement. This curved path design, combined with the crank mechanism, provides mechanical advantage that reduces the force required for adjustment while increasing the speed of angle change. The arc-shaped guide ensures smooth motion along a predetermined path
Solution Approach 2:
The transmission member acts as an intermediary between the operating member and the lock base. It converts the rotational motion of the operating member into arc-shaped movement of the lock base, providing mechanical leverage that reduces operational force and increases adjustment speed
3Manufacturing precision
If a simple connection structure is used, then the assembly is easy to manufacture, but the precision of angle positioning is insufficient
Solution Approach 1:
The guide portions are pre-designed with specific arc trajectories that define the exact movement path of the lock base. This preliminary design of the guide geometry ensures precise angle positioning is achieved automatically during operation, without requiring complex adjustment mechanisms or high-precision manufacturing of multiple components
Solution Approach 2:
The mechanism uses its own geometric design (arc-shaped guide portions and crank mechanism) to automatically achieve precise angle positioning. The structure self-regulates the movement path and positioning accuracy through its inherent geometry, eliminating the need for external positioning devices or complex manufacturing tolerances

Implementation Method 1
the first guide portion is guidingly cooperated with the first transmission member, and when the operating member moves, the operating member drives the first lock base to move along a preset arc direction through the first transmission member
Implementation Method 2
the second guide portion is guidingly cooperated with the second transmission member; and when the operating member moves, the operating member drives the second lock base to move along the preset arc direction through the second transmission member
Implementation Method 3
the first transmission member includes a first sliding rod and a first transmission rod, wherein the first sliding rod is connected with the first lock base, a first end of the first transmission rod is sleeved on the first sliding rod, a second end of the first transmission rod is rotatably connected with the operating member
