Transport Container Floor Pan Projection for Pivot Shaft Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport and storage containers require precise angular positioning of side walls during assembly, making manual and automatic assembly complex and prone to incomplete or faulty assembly due to the parallel orientation of mounting grooves with respect to the floor pan.
Innovation Solution
A projection on the inner surface of the floor pan extends into the recess, guiding the pivot shaft inclinedly, ensuring it is automatically pushed sideways into openings, and a barb element prevents disassembly in the open position, allowing for simple and secure assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If mounting grooves are arranged parallel to the pivot shaft in the prior art design, then the structural simplicity is maintained, but the assembly precision and ease of assembly deteriorate due to the requirement for precise angular positioning
Solution Approach 1:
The projection extending into the recess acts as an intermediary element that guides the pivot shaft during assembly. It provides a physical reference that mediates between the mounting groove and the pivot shaft, ensuring proper angular positioning without requiring complex alignment procedures or precise angular positioning of the side walls.
Solution Approach 2:
The solution transitions from a two-dimensional alignment problem (angular positioning in the horizontal plane) to a three-dimensional solution by adding vertical guidance through the projection. The pivot shaft is guided both vertically by the projection and horizontally by the mounting groove, creating a forced guidance path that simplifies assembly.
2Stability of the object's composition
If the locking profile engages with the mounting groove at a specific angle in the prior art, then the connection stability is achieved, but the ease of operation deteriorates due to the complexity of manual and automatic assembly
Solution Approach 1:
The projection is pre-positioned in the recess to provide guidance before the actual engagement of the locking profile with the mounting groove occurs. This preliminary guidance action ensures that when the side wall is inserted, the pivot shaft is already properly oriented, making the subsequent engagement simple and reliable without requiring precise angular positioning during assembly.
Solution Approach 2:
The projection and mounting groove configuration enables the assembly process to guide itself. The geometric relationship between the projection, recess, and mounting groove automatically provides the correct angular positioning and guidance, allowing both manual and automatic assembly without complex external guidance systems or precise positioning requirements.
3Device complexity
If the pivot shaft is inserted vertically into the recess without guidance features, then the device complexity is minimized, but the reliability of assembly deteriorates due to the possibility of incomplete or faulty assembly
Solution Approach 1:
The projection serves as a simple intermediary feature that significantly improves assembly reliability. It provides physical guidance that ensures the pivot shaft is correctly positioned during insertion, preventing incomplete or faulty assembly without adding complex guidance mechanisms or increasing overall device complexity.
Solution Approach 2:
By adding the vertical projection feature to the otherwise simple horizontal mounting groove design, the patent introduces a third dimension of guidance. This vertical guidance element works in conjunction with the horizontal mounting groove to create a forced guidance path that reliably positions the pivot shaft without significantly increasing device complexity.
