Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fold-type stand mechanism is used, then the device structure is simple, but the machine can only be propped up at one predetermined angle
Solution Approach 1:
The stand mechanism transitions from a fixed fold-type structure to a dynamic linkage system with a sliding member that enables continuous adjustment of the opening angle. The sliding member moves linearly within guide grooves, allowing the stand member to rotate and the link member to adjust the propping angle dynamically according to user needs.
Solution Approach 2:
The stand device is divided into distinct functional segments: a base member with guide grooves, a sliding member that moves independently, a stand member that rotates, and a link member that connects them. This segmentation allows each component to perform its specific function while contributing to the overall angle adjustment capability.
2Reliability
If a simple connection structure is used, then the device is easy to manufacture, but frequent failures occur
Solution Approach 1:
The connection between the sliding member and stand member uses curved guide grooves instead of straight linear guides. This curved geometry provides smoother motion transitions, reduces stress concentrations, and enhances the durability of the connection while maintaining manufacturability through standard machining processes.
Solution Approach 2:
The linkage design incorporates geometric constraints and guide grooves that pre-determine the motion paths of all components. This beforehand constraint design prevents misalignment and excessive forces during operation, cushioning against potential connection failures before they occur.
3Ease of operation
If a fold-type stand mechanism is used, then the device is compact, but user convenience is reduced due to fixed angle
Solution Approach 1:
The mechanism enables dynamic angle adjustment during operation, allowing users to change the propping angle on the fly. The sliding member can move along the curved guide grooves to adjust the opening angle, providing multiple operation modes while maintaining a relatively compact structure when folded.
Solution Approach 2:
The stand device serves multiple functions: it can prop up the machine at various angles for different viewing or working positions, and the same linkage mechanism also provides structural support and stability. This multi-functionality increases user convenience without proportionally increasing complexity.

AI summary
A stand device capable of providing different folding angles includes a base member, a sliding member disposed to the base member so that a linear reciprocal motion is possible, a stand member having a specific length and fastened to one end of the sliding member in a rotatable manner, and a link member, of which one end is hinge-connected to a proper place in the stand member and the other end is hinge-connected to the base member, for holding the stand member, wherein an opening angle of the stand member varies depending on a linear reciprocation level of the sliding member.
