Pull-Down Lock Assembly for Single-Person Tent Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional folding tents require multiple steps and often need two or more people to fold and unfold, making the process complicated and inefficient.
Innovation Solution
A pull-down lock mechanism with a movable part base and pull-down components that allow for single-person operation by releasing the lock bolt component when the movable part base is pulled downward, simplifying the folding and unfolding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional locking mechanisms are used on each support leg, then the tent can be securely locked during unfolding, but the folding and unfolding process becomes complicated and requires multiple steps
Solution Approach 1:
The patent merges multiple locking mechanisms into a single integrated pull-down lock assembly that can simultaneously lock multiple support legs. The lock assembly includes a main body with multiple locking arms that can engage with different support legs through a single pulling action, eliminating the need for separate locking operations on each leg and simplifying the overall folding process while maintaining secure locking.
Solution Approach 2:
The pull-down lock assembly is designed as a universal mechanism that can lock multiple different support legs with varying configurations. The locking arms are adjustable and can adapt to different leg positions and orientations, allowing a single lock assembly to perform multiple locking functions that would traditionally require separate mechanisms for each support leg.
2Reliability
If traditional locking mechanisms are used on each support leg, then each part can be individually locked, but the operating efficiency is reduced due to many steps
Solution Approach 1:
The patent combines multiple individual locking operations into a single integrated action. The pull-down lock assembly incorporates multiple locking arms that can simultaneously engage with multiple support legs through one pulling motion, maintaining the ability to individually secure each support leg while dramatically reducing the number of operational steps required and improving overall operating efficiency.
3Stability of the object's composition
If traditional locking mechanisms are used, then the tent structure can be stabilized, but two or more people are needed to cooperate in the folding and unfolding process
Solution Approach 1:
The patent merges multiple locking functions into a single operable assembly that can be manipulated by one person. The pull-down lock assembly includes integrated locking arms and a central pulling mechanism that allows a single operator to simultaneously engage or disengage multiple support legs, maintaining structural stability while enabling single-person operation without requiring coordination between multiple people.
4Reliability
If multiple locking points are used on support legs, then the tent can be securely fixed during unfolding, but the process takes many steps and is time-consuming
Solution Approach 1:
The patent combines multiple locking points into a single integrated pull-down lock assembly that can simultaneously engage with multiple support legs. The design allows all locking points to be activated or deactivated through one pulling action, maintaining secure fixation of the tent structure while dramatically reducing the time required for folding and unfolding operations compared to sequential locking of individual points.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient, single-person operation of folding and unfolding tents by releasing the lock mechanism with a simple downward pull, enhancing operational efficiency.
Implementation Method 1
the elastic thrust component for pushing the left lock bolt and the right lock bolt to move and clamp the bottom end of the pull rod is arranged in the movable part upper cover
Implementation Method 2
the elastic thrust component includes the spring, one end of which abuts against the movable part upper cover, and the other end of which abuts against the left lock bolt or the right lock bolt

AI summary
A pull-down lock, may include a top cover, wherein the bottom end of the top cover is fixedly connected with the pull rod, and the bottom end of the pull rod is fixedly connected with the lock head; besides, the lock bolt component for limiting and fixing the lock head is arranged in the movable part upper cover, and the movable part base is slidably inserted into the bottom end of the movable part upper cover; the movable part base is internally provided with the pull-down component which is adapted to and penetrates through the lock bolt component. When the movable part base is pulled to move downwards, the lock bolt component could be pushed to move under the cooperation of the pull-down component, so that the limiting and fixation of the lock head is released.
