Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional stopping means are used, then the tray can be stopped at a designated position, but the stopping travel can only be adjusted to a limited extent and the structure is complex and highly priced
Solution Approach 1:
The stopping device employs a dynamic structure where the first core part can reciprocate within the shock absorbing cavity, allowing the stopping travel to be continuously adjusted by controlling the position of the first core part. This dynamic adjustment mechanism replaces the limited discrete adjustment of conventional stopping means, enabling stepless adjustment of stopping travel while maintaining a relatively simple structure.
Solution Approach 2:
The invention uses a shock absorbing cavity containing a pressure medium (gas or liquid) to provide damping force during the stopping process. The first core part moves within this fluid-filled cavity, and the fluid's compressibility and viscosity enable both the stopping action and the adjustable travel. This pneumatic/hydraulic approach simplifies the structure compared to mechanical spring-based or purely mechanical adjustment mechanisms.
2Reliability
If conventional stopping means are used, then the tray can be stopped, but the structure is complex and highly priced causing the cost of the conveying system to increase
Solution Approach 1:
The invention combines the stopping function and the shock absorption function into a single integrated device. The first piston assembly simultaneously provides the stopping force and the damping effect through the shock absorbing cavity, eliminating the need for separate stopping mechanisms and cushioning devices. This merging of functions reduces structural complexity and overall system cost while maintaining reliable stopping performance.
Solution Approach 2:
The stopping device utilizes the compressibility and viscosity parameters of the pressure medium in the shock absorbing cavity to provide reliable stopping. By adjusting parameters such as the type of pressure medium, its pressure, and the geometry of the cavity, the stopping characteristics can be optimized for reliability without requiring complex mechanical structures.
3Object-affected harmful factors
If conventional stopping means are used, then the tray can be stopped, but the impact during stopping causes damage
Solution Approach 1:
The shock absorbing cavity is pre-filled with a pressure medium that is ready to absorb impact energy. When the first core part moves during the stopping process, the pressure medium immediately provides cushioning force to reduce impact. This beforehand cushioning prevents damage to the tray and workpiece without requiring complex active control systems or multiple cushioning stages.
Solution Approach 2:
The invention converts the harmful impact force during stopping into useful work by allowing the first core part to move within the shock absorbing cavity. The kinetic energy of the moving tray is transformed into potential energy of the compressed pressure medium and viscous dissipation in the fluid, effectively reducing impact damage. This energy conversion approach simplifies the structure compared to systems that attempt to actively counteract or absorb impact through complex mechanisms.
