Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity and time-consuming nature of using core drill bits to form large diameter holes in walls due to the difficulty in maintaining correct positioning of the drill bit and the need for a guide member, which requires additional steps like pilot hole drilling and guide member removal.
Innovation Solution
A support device with a recess and vacuum connector that secures the drill bit in place using suction, eliminating the need for pilot holes and guide members by providing continuous support and dust extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a guide member is fitted within the core drill bit to guide and support the drill bit during initial drilling, then the drill bit positioning accuracy is improved, but the device complexity and operation time increase due to additional steps of pilot hole drilling, guide member fitting, and guide member removal
Solution Approach 1:
The patent removes the guide member from the drilling system entirely. Instead of using a separate guide member that needs to be fitted and removed, the invention integrates positioning functionality directly into the drill bit through positioning elements that engage with the wall surface, eliminating the need for pilot holes and guide members
Solution Approach 2:
The patent combines the positioning function and drilling function into a single integrated drill bit assembly. The positioning elements are built into the drill bit body itself, merging what were previously separate components (guide member and drill bit) into one unified tool, thereby simplifying the overall drilling operation
2Stability of the object's composition
If a guide member is used to support the core drill bit during initial drilling, then the drill bit stability is improved, but the loss of time increases due to multiple operational steps including pilot hole drilling, guide member fitting, drilling, guide member removal, and reintroduction of the drill bit
Solution Approach 1:
The positioning elements are pre-integrated into the drill bit design, eliminating the need for preliminary pilot hole drilling and guide member fitting. The drill bit is ready for immediate use with built-in positioning capabilities, performing the positioning function automatically as part of the drilling operation itself
Solution Approach 2:
The invention enables continuous drilling operation without interruptions. The drill bit remains in place throughout the entire drilling process, eliminating the need to retract, remove guide members, and reintroduce the drill bit. The positioning elements maintain drill bit stability continuously from start to finish of the drilling operation
3Area of moving object
If the drill bit is large in diameter to form the required opening, then the opening capability is improved, but the ease of operation worsens due to difficulty in holding and positioning the large drill bit
Solution Approach 1:
The positioning elements act as intermediaries between the large drill bit and the wall surface. These elements provide mechanical engagement points that facilitate easy positioning and holding of the large diameter drill bit, making it as easy to operate as smaller drill bits would be
