Solution Overview
Problem
Conventional connecting devices for leg parts and beams lack adjustability in angle and cannot be folded for storage, resulting in increased volume and reduced practicality.
Innovation Solution
A connecting device that includes a leg part connection frame, a fixing unit with a pressing plate and a fixing bolt, and a footplate, allowing for strong and adjustable connections between leg parts and beams, with the option to fold the leg parts under the beam for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional clamp is used to connect leg parts and beam, then the connection is simple, but the angle cannot be adjusted after assembly and the connection strength is insufficient
Solution Approach 1:
The connecting device incorporates a dynamic adjustment mechanism that allows the leg parts to be positioned at different angles relative to the beam during assembly, and then locked into place. The connection frame includes movable joints and positioning features that enable angular adjustment while maintaining structural integrity once assembled.
Solution Approach 2:
The connecting device is divided into separate functional components including a connection frame, leg parts, beam interface, and locking mechanism. This segmentation allows independent optimization of each component - the frame provides structural support, while the locking mechanism ensures strong connection, and the joint design enables angle adjustment.
2Stability of the object's composition
If the beam and leg parts are kept extended for use, then the structure is stable, but the storage volume cannot be reduced
Solution Approach 1:
The connecting device incorporates hinges and joint mechanisms that enable the leg parts to be dynamically repositioned from an extended operational position to a folded storage position. The dynamic design maintains structural stability during use while allowing compact configuration for storage, effectively resolving the contradiction between stability and volume reduction.
Solution Approach 2:
The leg parts are designed to fold underneath and nest against the beam structure when not in use, creating a compact nested configuration. This nesting arrangement significantly reduces the overall volume required for storage while maintaining the full extended length and structural stability when deployed for operation.
3Reliability
If only a pressing plate is used to connect leg parts and beam, then the device is simple, but the connection becomes loose under external impact
Solution Approach 1:
The connecting device merges multiple connection mechanisms into a single integrated system. The pressing plate is combined with a fixing bolt, locking mechanism, and connection frame to create a multi-functional assembly that provides both strong connection and impact resistance without requiring separate independent components for each function.
Solution Approach 2:
The connecting device incorporates pre-designed shock-absorbing features and flexible joint elements that cushion against external impacts before they can compromise the connection. The pressing plate and fixing bolt are positioned and sized to provide inherent resistance to impact forces, preventing connection loosening without requiring complex active control systems.
