Innovation Solution
A Point-of-Sale system with a support base featuring a base plate and suspension arm design that includes a curved chamfer to enhance structural support, along with a pivot mechanism and locking mechanism for easy assembly and disassembly, ensuring the display screen and host computer can be stably supported and quickly repaired or replaced.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the display screen is mounted on a support base with a simple structure, then the device complexity is reduced, but the display screen becomes unstable and shakes when touched
Solution Approach 1:
The patent applies the dynamics principle by introducing a pivot mechanism that allows the display screen to rotate between a first position (supported by the suspension arm) and a second position (supported by the base plate). This dynamic positioning system enables the display screen to adapt to different operational states, providing stability during use while facilitating easy access during maintenance, thus resolving the contradiction between structural simplicity and stability.
2Stability of the object's composition
If the display screen is firmly fixed to the support base, then the display screen stability is improved, but the assembly and disassembly process becomes complicated and time-consuming
Solution Approach 1:
The pivot mechanism enables dynamic repositioning of the display screen between two stable states. In the first position, the display screen is firmly supported for stable operation. In the second position, the display screen can be easily detached for maintenance. This dynamic design eliminates the need for complex fixed mounting structures while ensuring stability during use and rapid disassembly for repairs.
3Ease of repair
If the display screen is easily detachable from the support base, then the ease of repair is improved, but the display screen stability during use is reduced
Solution Approach 1:
The pivot mechanism provides two distinct operational states: a first position where the display screen is firmly supported by the suspension arm for stable use, and a second position where the display screen can be easily detached for repair. The ability to dynamically transition between these states ensures both operational stability and ease of maintenance without compromise.
4Stability of the object's composition
If the support base uses a robust structural design, then the display screen stability is improved, but the device complexity increases
Solution Approach 1:
The support base is segmented into distinct functional components: a base plate for stable mounting, a suspension arm for supporting the display screen in the first position, and a pivot mechanism for transitioning between positions. This segmentation allows each component to be optimized for its specific function while maintaining overall structural robustness without excessive complexity.
Solution Approach 2:
The dynamic pivot mechanism replaces the need for overly complex fixed mounting structures. By allowing controlled movement between two stable positions, the system achieves robust support with a relatively simple mechanical design, avoiding the need for complex adjustment mechanisms or over-engineered fixed mounts.
