Pivoting Light Hook Lock for Fast Truss Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light hooks require extensive and time-consuming rotation of a nut to detach from a truss or column, making disassembly difficult and inefficient.
Innovation Solution
A light hook design featuring a pulling member, connecting bar, and fixing member that allows quick disassembly by reversing the pulling end to change the connecting bar's position, enabling the fixing member to move away from clamping portions and unlock the hook.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a nut and locking member structure is used to secure the light hook, then the locking reliability is improved, but the disassembly time and operational complexity increase significantly
Solution Approach 1:
The locking mechanism is segmented into distinct functional components: the locking member with protrusions, the slot with clamping portions, and the releasing member. This segmentation allows the locking function to be separated from the releasing function, enabling quick release without undoing the entire locking mechanism. The locking protrusions engage with the slot to provide secure locking, while the releasing member independently controls the disengagement process.
Solution Approach 2:
The releasing member acts as an intermediary mechanism between the user and the locking member. Instead of directly manipulating the locking member or nut, the user operates the releasing member, which then triggers the disengagement of the locking protrusions from the slot. This intermediary mechanism simplifies the disassembly operation to a single pulling action rather than requiring extensive rotation of a nut.
2Reliability
If a nut must be rotated almost to the end of the locking member for detachment, then the locking security is ensured, but the ease of operation deteriorates due to the time-consuming rotation action
Solution Approach 1:
The conventional approach requires rotation to achieve disengagement, but this invention inverts the logic: the locking is achieved through engagement of protrusions with the slot, and disengagement is achieved by pulling the releasing member in the opposite direction of engagement. This inversion transforms a rotational tightening action into a linear pulling action for release, significantly improving ease of operation while maintaining locking security through the protrusion-slot engagement mechanism.
3Device complexity
If a conventional nut and locking member system is used, then the structural simplicity is maintained, but the productivity decreases due to the considerable time required for disassembly
Solution Approach 1:
The releasing member is designed with dynamic characteristics, allowing it to pivot about a pivot point and translate the pulling motion into the necessary movement of the locking member. This dynamic mechanism enables quick disengagement through a simple pulling action on the releasing member, which rotates and pulls the locking protrusions out of the slot, significantly improving assembly and disassembly productivity without overly complicating the overall structure.
