Collapsible Leg Assembly With Segmented Crossbar for Self-Leveling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-leveling devices with triangular pivoting leg assemblies face challenges in transportation and storage due to their rigid structure, which complicates the maintenance of platforms in a level position on uneven surfaces.
Innovation Solution
The development of collapsible leg assemblies with a crossbar system that includes flexibly or detachably connected sections, allowing the legs to fold and occupy less space, facilitating easier transportation and storage while maintaining the ability to self-level on uneven surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid triangular pivoting leg assemblies are used for self-leveling devices, then the ability to maintain platform level position on uneven surfaces is improved, but transportation and storage become more difficult due to increased space occupation
Solution Approach 1:
The crossbar is divided into multiple sections that can be detached or flexibly connected. The first crossbar section and second crossbar section can be separated, allowing the leg assembly to be disassembled into smaller components for compact storage and transportation while maintaining the full rigid structure when assembled for use.
Solution Approach 2:
The crossbar transitions from a static rigid structure to a dynamic configurable structure. The flexible connection or detachable mechanism allows the crossbar to change its configuration - remaining rigid during operation for stability but becoming collapsible or separable during transportation and storage.
2Ease of operation
If collapsible leg assemblies with detachable crossbar sections are used, then transportation and storage become easier, but the structural integrity and stability during use may be compromised
Solution Approach 1:
The crossbar is segmented into detachable sections with connection mechanisms designed to provide secure attachment during use. The segmentation enables easy assembly and disassembly for transportation while the connection design ensures structural integrity is maintained when assembled and loaded.
Solution Approach 2:
The connection mechanisms are pre-designed and pre-positioned on the crossbar sections to ensure proper alignment and secure attachment before use. This preliminary preparation ensures that when the sections are assembled, the structural integrity is immediately restored without requiring complex assembly procedures.
