Deformable Collar Cap with Screw-Nut Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressurized fluid bottle valve protection caps require complex assembly and disassembly processes, often damaging the attachment system and necessitating separate tools or parts, which complicates the installation and removal of caps.
Innovation Solution
A valve protection cap with a deformable collar system featuring a screw and nut mechanism, where each housing has stop walls to transmit forces for separating or approximating the collar portions, facilitating easy assembly and disassembly without additional tools, by adjusting the collar's diameter through the screw/nut system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid mounting collar is used to secure the cap to the bottle, then the attachment strength is improved, but the assembly and disassembly process becomes difficult and may damage the attachment system
Solution Approach 1:
The mounting collar is divided into two separable portions that can be independently positioned and secured. This segmentation allows the collar to be assembled by separating the portions during installation and then locking them together, providing both strong attachment and ease of assembly/disassembly without damaging the attachment system
Solution Approach 2:
The collar transitions from a static rigid structure to a dynamic assembly where the two portions can move relative to each other during assembly and disassembly. The portions can be separated to facilitate installation and then locked in place to provide secure attachment, enabling easy operation while maintaining strength
2Ease of operation
If a deformable collar structure is used to facilitate assembly and disassembly, then the ease of operation is improved, but the structural complexity increases
Solution Approach 1:
Instead of using a complex deformable structure, the collar is segmented into two simple portions that can be independently handled. This segmentation simplifies the structure while enabling easy assembly and disassembly operations
Solution Approach 2:
A locking mechanism acts as an intermediary element between the two collar portions, securing them together after assembly. This intermediary component enables the complex function of secure attachment without requiring the collar itself to be structurally complex
3Adaptability or versatility
If separate tools and parts are used for collar adjustment, then the adaptability is improved, but the device complexity and number of components increases
Solution Approach 1:
The adjustment and locking functions are merged into an integrated mechanism where the two collar portions work together with a single locking system. This eliminates the need for separate tools and parts while maintaining the adaptability to adjust and secure the collar
Solution Approach 2:
The locking mechanism serves multiple functions: it secures the two collar portions together, maintains the adjusted diameter, and enables easy disassembly. This multi-functionality provides adaptability without increasing the number of components

Function Achieved in This Case
Enables efficient and tool-free assembly and disassembly of the cap on the bottle, reducing the risk of damaging the attachment system and simplifying the process, while maintaining secure locking during use.
Implementation Method 1
each housing comprising respective walls forming a system of stops for the screw head and the nut respectively to transmit a clamping force
Implementation Method 2
the walls of the housings forming a system of stops for the screw head and nut respectively to also transmit a force of separation of the two portions of the collar when unscrewing the nut relative to the screw

AI summary
The invention relates to a fluid bottle tap protective cap (1) including a mounting collar (4) consisting of at least two portions (41, 42) that are movable or deformable relative to each other so as to increase or decrease the diameter of said collar (4). The cap (1) also includes a device for clamping the cap (4) for decreasing the diameter of said cap and includes a screw (47) and nut (48) system. The two portions (41, 42) of the collar (4) each include one recess (44, 45) for a screw (47) and nut (48) system. A first recess (44) is provided to receive: a first end of a head (46) of the screw (47) of the screw and nut system, and the second recess (45) is provided to receive the second end of the screw (47) and a nut (48) engaging with the screw (47), each recess (44, 45) including respective walls (144, 244, 145, 245) forming a system of abutments for the head (46) of the screw and the nut (48), respectively, in order to transmit a force for clamping and separating the two portions (41, 42) of the collar (40) when the nut (48) is unscrewed from or screwed onto the screw (47).
