Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators in the construction industry face issues with silica contamination and debris during drilling operations, leading to small cuts and other problems.
Innovation Solution
A contamination containment shield comprising a sleeve and an enclosure with baffles is designed to fit around a drill bit, protecting the operator from debris by containing contaminants such as silica and concrete dust.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a drill machine is used for drilling operations, then productivity is improved, but silica contamination and debris are generated causing harm to operators
Solution Approach 1:
The patent introduces a contamination containment shield as an intermediary device between the drill bit and the operator. The shield includes a sleeve that attaches to the drill chuck and an enclosure with baffles that contain debris and silica dust, preventing direct contact with the operator while allowing the drilling operation to proceed efficiently.
Solution Approach 2:
The shield is designed to prevent contamination before it can reach the operator. The enclosure with circumferential baffles creates a barrier that stops silica dust and debris at the source, eliminating the need for post-exposure treatment or cleanup of contaminated areas.
2Object-affected harmful factors
If a contamination shield is added to protect operators, then protection from debris is improved, but device complexity increases
Solution Approach 1:
The shield is divided into distinct functional segments: a sleeve portion that attaches to the drill chuck, an enclosure portion that contains the drilling operation, and multiple baffles within the enclosure. This segmentation allows each component to perform its specific function while keeping the overall design manageable and maintainable.
Solution Approach 2:
The shield utilizes a sleeve and enclosure structure that can be made from flexible or semi-flexible materials, allowing the device to adapt to the drilling environment while maintaining protection. The thin-walled construction provides adequate containment without excessive complexity or weight.
3Object-affected harmful factors
If an enclosure with baffles is used to contain contaminants, then contamination containment is improved, but ease of operation deteriorates due to installation and cleaning requirements
Solution Approach 1:
The shield is designed with dynamic characteristics that allow it to flex and adapt during operation. The enclosure can accommodate variations in drill bit length and drilling depth, and the baffles can move slightly to accommodate different drilling conditions, maintaining containment effectiveness without requiring precise adjustment.
Solution Approach 2:
The shield is designed as a relatively simple, inexpensive component that can be easily replaced if needed. The sleeve and enclosure can be detached and reattached quickly, and the baffles can be cleaned or replaced without requiring complex disassembly, reducing the operational burden on users.

AI summary
A contamination containment shield includes a sleeve and an enclosure. The sleeve may include a sleeve proximal end and a sleeve distal end. The sleeve proximal end may be configured to attach to a chuck of the drill machine. The enclosure may include an enclosure proximal end and an enclosure distal end. The enclosure proximal end may be attached to the sleeve distal end. The enclosure may be formed of multiple baffles disposed circumferentially around the enclosure.
