Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foreign material exclusion devices are not reliable, durable, or easy to maintain, and lack simplicity in design, making them complex for field assembly and disassembly during cleaning and replacement processes.
Innovation Solution
A foreign material exclusion device featuring a retaining member with a post and cap design, where the post and cap have through bores that align for secure engagement with an extraction member, providing enhanced strength and sealing capabilities, and incorporating a resilient foamed polymeric body for easy installation and removal, along with indicia for user information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing foreign material exclusion devices are used, then sealing function is provided, but reliability and durability are insufficient
Solution Approach 1:
The device is divided into distinct functional components: a resilient sealing body, a retaining member with post and cap, and an extraction member. This segmentation allows each component to be optimized for its specific function while improving overall reliability and ease of maintenance.
Solution Approach 2:
The post is inserted through the resilient body, and the cap is fitted over the post, creating a nested structure. The extraction member then passes through both the post and cap through-bores to secure the assembly. This nested design provides structural integrity while maintaining simplicity.
2Ease of repair
If existing foreign material exclusion devices are used, then sealing function is provided, but ease of maintenance is poor
Solution Approach 1:
The device is divided into distinct functional components: a resilient sealing body, a retaining member with post and cap, and an extraction member. This segmentation allows each component to be optimized for its specific function while improving overall reliability and ease of maintenance.
Solution Approach 2:
The resilient body can be removed and replaced by pulling on the extraction member, which is secured to the body. This allows easy recovery and replacement of the sealing element without damaging other components, significantly improving ease of maintenance.
3Ease of operation
If resilient foamed polymeric body is used, then easy installation and removal is achieved, but strength may be insufficient
Solution Approach 1:
The device combines a resilient foamed polymeric body with a rigid retaining member consisting of a post and cap, likely made from stronger materials. This composite structure provides both the ease of operation from the resilient body and the structural strength from the rigid components.
Solution Approach 2:
The post is inserted through the resilient body, and the cap is fitted over the post, creating a nested structure. The extraction member then passes through both the post and cap through-bores to secure the assembly. This nested design provides structural integrity while maintaining simplicity.
4Ease of operation
If through bores are added for extraction member, then ease of removal is improved, but device complexity increases
Solution Approach 1:
The device is divided into distinct functional components: a resilient sealing body, a retaining member with post and cap, and an extraction member. This segmentation allows each component to be optimized for its specific function while improving overall reliability and ease of maintenance.
Solution Approach 2:
The through-bores in the post and cap serve as intermediaries that guide and secure the extraction member. This simple structural feature enables easy removal and replacement of the resilient body without requiring complex mechanisms.

AI summary
A retaining member particularly suitable for use as part of a foreign material exclusion device that can be used to temporarily seal an area of a construction from foreign material or debris, wherein the retaining member includes a post adapted to be inserted through a body of the foreign material exclusion device and cap having a rim and a fitting, the latter mateably engageable with an end of the post. The post and fitting each include through bores that are alignable such that they can be connected, for example with an extraction member of the foreign exclusion material device. Foreign material exclusion devices including the retaining member are disclosed.
