Building Frame Linkage Node With Manual Locking Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing joining structures for frame structures of buildings, such as those using starfish-shaped and dish-shaped plates, require complex tool-based fixation and rotational insertion, complicating the assembly process.
Innovation Solution
A linkage unit with detachable link members and a lock mechanism that allows for manual switching between locked and unlocked states, simplifying the assembly process by eliminating the need for rotational alignment and tool-based fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If tool-based fixation means (bolts, external threads) are used to join frames and joining components, then the connection strength is improved, but the complexity of assembly work increases
Solution Approach 1:
The invention extracts the fixation function from separate tools (bolts, wrenches) and integrates it into the joining component itself through the lock mechanism. The pin portion with head and groove, along with the lever portion, forms an self-contained locking system that eliminates the need for external fixation tools while maintaining connection strength.
Solution Approach 2:
The joining component performs its own fixation through the lock mechanism. The lever portion can be manually operated to rotate the pin portion and engage the groove with the projection, allowing the component to self-lock without external tools. This self-service approach reduces assembly complexity while ensuring secure connections.
2Reliability
If rotational insertion is required for spherical joining components with bolt holes, then the connection reliability is improved, but the assembly time and operational ease deteriorate
Solution Approach 1:
The link member is pre-fixed to the frame before insertion into the node member. This preliminary action eliminates the need for rotational alignment during final assembly, as the link member with attached frame is simply inserted into the to-be-linked portion without requiring rotational movement for positioning.
Solution Approach 2:
The invention removes the rotational insertion requirement entirely by using a different joining mechanism. Instead of rotating spherical components with bolt holes, the system uses a linear insertion of the link member followed by engagement of the lock mechanism, eliminating the time-consuming rotational alignment step.
3Stability of the object's composition
If complex joining structures with multiple fixation means are used, then the structural stability is improved, but the device complexity increases
Solution Approach 1:
The invention merges multiple functions (connection, fixation, locking) into a single integrated joining component. The node member with to-be-linked portions, link members with lock mechanisms, and integrated pin-lever system combine to provide both connection and secure fixation without requiring separate components for each function, thus reducing overall device complexity.
Solution Approach 2:
The joining component serves multiple functions: the to-be-linked portions provide connection interfaces, the pin portion with groove provides fixation, the lever portion enables locking, and the projection engages with the groove for retention. This multi-functional design achieves structural stability without increasing device complexity through the use of a unified component.
