Foldable Hook Mechanism for Caulking Gun Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional caulking guns lack convenience in carrying, storage, and use due to their fixed hook portions, which cannot be adjusted or folded.
Innovation Solution
A caulking gun design featuring two movable hook portions that can be translated, rotated, or swung relative to each other, allowing for adjustable positioning and easy folding/unfolding for enhanced usability and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the hook portion is integrally formed with the plunger as one piece, then the structural strength is improved, but the ease of operation deteriorates because the hook portion cannot be adjusted or folded
Solution Approach 1:
The hook pull portion is divided into a first hook portion and a second hook portion that can be folded relative to each other. This segmentation allows the hook structure to be collapsed into a compact form for storage and carrying, while maintaining the integral connection to the plunger for structural strength during operation.
Solution Approach 2:
The hook portions are designed to be movable relative to each other through a folding mechanism. This dynamic capability allows the hook structure to transition between an extended operational position and a folded storage position, improving ease of operation without compromising structural integrity when deployed.
2Ease of manufacture
If the hook portion is fixed and cannot be folded, then the manufacturing simplicity is improved, but the ease of operation deteriorates due to inconvenience in carrying and storage
Solution Approach 1:
The hook pull portion is segmented into foldable first and second hook portions connected by a hinge or pivot joint. This segmentation enables compact folding for storage while maintaining relatively simple manufacturing processes through standard hinge mechanisms and integral forming techniques.
Solution Approach 2:
The foldable hook portions can be nested or collapsed into a compact configuration when not in use, similar to a nested doll structure. This allows the caulking gun to have a smaller storage footprint without requiring complex disassembly mechanisms.
3Ease of operation
If the hook portion is made movable and foldable, then the ease of operation is improved for carrying and storage, but the device complexity increases
Solution Approach 1:
The hook pull portion is divided into two main segments (first and second hook portions) connected by a simple hinge or pivot joint. This segmentation provides the necessary folding capability while maintaining relatively simple construction compared to more complex articulated mechanisms.
Solution Approach 2:
A single degree-of-freedom folding mechanism is implemented between the first and second hook portions, providing the necessary dynamic capability for folding and unfolding while avoiding the complexity of multi-axis articulation or actuation systems.
