Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional tripods use manual adjustment mechanisms for platform leveling, then the structure remains simple and portable, but the precision and speed of leveling adjustment are insufficient
Solution Approach 1:
The leveling adjustment mechanism is segmented into two distinct systems: a manual gross positioning mechanism for coarse adjustments and an automated fine positioning mechanism for precision leveling. This segmentation allows each subsystem to be optimized independently, achieving high precision without requiring the entire system to be complex.
Solution Approach 2:
The patent introduces an automated fine positioning mechanism as an intermediary between the manual gross positioning and the final platform level. This intermediary component handles the precision adjustment task, freeing the manual mechanism from precision requirements while maintaining overall system simplicity.
2Strength
If tripods are designed with robust construction for heavy loads, then load capacity increases, but portability and ease of installation decrease
Solution Approach 1:
The patent replaces manual mechanical adjustment operations with an automated fine positioning mechanism that can be controlled remotely or autonomously. This substitution reduces the physical effort and skill required by operators while maintaining the structural strength needed for heavy loads.
Solution Approach 2:
The system performs preliminary gross positioning manually to bring the platform close to the desired level, then the automated mechanism takes over for final precision adjustment. This preliminary action reduces the workload during installation and operation.
3Measurement precision
If automated fine positioning mechanisms are added to improve leveling precision, then leveling accuracy increases, but device complexity and cost increase
Solution Approach 1:
The leveling system is divided into independent gross positioning and fine positioning subsystems. The automated fine positioning mechanism operates independently after the manual gross positioning is complete, allowing the precision feature to be added without fundamentally redesigning the entire tripod structure.
Solution Approach 2:
The patent implements a dynamic switching mechanism where the system transitions from manual gross positioning mode to automated fine positioning mode. This dynamic operation allows the complex automated features to be engaged only when needed, maintaining simplicity during transport and setup phases.
4Productivity
If manual gross positioning mechanisms are used, then the structure remains simple and portable, but the speed and efficiency of installation decrease
Solution Approach 1:
The positioning process is segmented into two phases: rapid manual gross positioning for quick initial setup, followed by automated fine positioning for precision leveling. This segmentation enables fast installation while incorporating automation only where it provides the most benefit.
Solution Approach 2:
The system maintains continuous useful action by seamlessly transitioning from manual to automated positioning without interruption. The automated fine positioning mechanism engages immediately after gross positioning, eliminating idle time and maximizing installation efficiency.

AI summary
A support structure is provided that can comprise a central support member and leveling devices arranged in a deployed configuration where the leveling devices are radially offset from the central support member. In one embodiment of the support structure, each of the leveling devices can comprise an actuator assembly for fine positioning of a support plane of the support structure. The actuator assembly can communicate with a control system, and in one example the control system is operatively configured to monitor the position of the support plane, providing feedback in the form of a control that operates the actuator to adjust the orientation of the support plane.
