Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing endoscopic systems face challenges with the high cost and complexity of delivering sterile water, requiring specific connections and separate setups for irrigation and secondary gas sources, which limits their versatility and efficiency.
Innovation Solution
A water bottle cap assembly designed to be cost-effective, adaptable to various endoscopic devices and water sources, featuring multiple ports and tubular members for fluid communication, with an adaptor for specific endoscopic devices, and options for threadless or adhesive-free attachment, enabling the use of CO2 as a secondary gas source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional endoscopic systems use separate connections and setups for water delivery, irrigation, and secondary gas sources, then each function can be provided, but the device complexity and cost increase significantly
Solution Approach 1:
The cap assembly is designed with multiple ports (first port for water delivery, second port for secondary gas source, third port for irrigation) that can simultaneously accommodate different connections. The adaptor with its multiple openings and sealing members enables a single device to perform multiple functions including water delivery, gas insufflation, and irrigation, eliminating the need for separate dedicated setups for each function.
2Reliability
If conventional systems use manufacturer-specific fittings for water bottle connections, then compatibility with specific endoscopes is ensured, but adaptability to various endoscopic devices is reduced
Solution Approach 1:
The adaptor serves as an intermediary component between the water bottle cap and the endoscopic device. It features a first opening that receives the water bottle fitting and a second opening that connects to the endoscope, with sealing members ensuring reliable fluid-tight connections. This intermediary design allows compatibility with different manufacturers' specific fittings while maintaining adaptability to various endoscopic devices.
3Productivity
If multiple separate connections are used for water delivery, gas sources, and irrigation, then each function is provided, but the number of connections and setups increases
Solution Approach 1:
The invention merges multiple connection functions into a single integrated cap assembly. The first port, second port, and third port are all incorporated into one cap that attaches to a single water bottle, allowing simultaneous connection for water delivery, secondary gas source, and irrigation. This consolidation reduces the number of separate connections and setups required compared to conventional systems.

AI summary
Embodiments of the present invention provide water bottle cap assemblies suitable for attachment to an endoscopic device and a water source. The water bottle cap assembly can include a plurality of ports and an engageable member to sealingly engage the cap with a water source. The assembly also includes a plurality of tubular members, each tubular member coupled to a respective port so as to be in fluid communication therewith. The assembly can include a cap having a grippable surface that is overmolded onto the cap. The cap can also have a soft inner seal on the interior surface, and the soft inner seal can be integrally formed with the overmolded grippable surface. The cap can have a top that is pressfit onto the main portion of the cap. The grippable surface material can be overmolded over the top of the cap.
