Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for drilling and countersinking terrace floor slats are time-consuming, imprecise, and aesthetically flawed, often requiring tracing and measurement, which can lead to irregular screw placements and increased risk of screw breakage, while also compromising the esthetic appearance of the terrace.
Innovation Solution
A drilling assistance device with a rigid body and cylindrical guide spaces that allows for orthogonal drilling and countersinking in a single step, eliminating the need for tracing and ensuring precise, aesthetically pleasing screw placements without measuring or using tools like tape measures or pencils.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If tracing is used to mark drill hole positions on the slat surface, then the position of each screw can be determined, but the process becomes time-consuming and the tracing may remain visible compromising the esthetic appearance
Solution Approach 1:
The device pre-defines the positions of guide spaces on the rigid body before contact with the slat. When the rigid body is placed on the slat surface, the guide spaces are already positioned at the correct locations for drilling, eliminating the need for time-consuming measurement and tracing operations during the mounting process
Solution Approach 2:
The rigid body acts as an intermediary tool that transfers the pre-determined screw positions from the device design to the slat surface. The guide spaces on the rigid body serve as mediators that directly guide the drill bit to the correct positions without requiring manual marking on the slat
2Ease of operation
If manual measurement and tracing is performed to determine screw positions, then screw placement can be achieved, but the regularity and precision of screw distribution is compromised due to measurement errors
Solution Approach 1:
The device performs self-positioning through the guide spaces that are built into the rigid body structure. The guide spaces automatically ensure correct spacing and positioning of drill holes without requiring the operator to perform measurements or calculations, thereby guaranteeing regular screw distribution while maintaining simple operation
Solution Approach 2:
The rigid body is segmented into multiple guide spaces, each corresponding to a specific screw position. This segmentation allows the device to handle multiple screw positions simultaneously with pre-determined spacing, ensuring regularity without manual measurement for each individual hole
3Ease of operation
If oblique drilling is performed instead of orthogonal drilling, then drilling may be easier to execute, but the screw head protrudes from the slat surface creating safety hazards and aesthetic defects
Solution Approach 1:
The guide spaces are pre-configured in the rigid body to enforce orthogonal drilling orientation before the drilling operation begins. The cylindrical walls of the guide spaces are designed to guide the drill bit perpendicular to the slat surface, preventing oblique drilling and the associated safety hazards before they can occur
Solution Approach 2:
The guide spaces serve as intermediary structures that mediate between the drill bit and the slat surface. By constraining the drill bit within the cylindrical guide spaces, the device ensures orthogonal drilling orientation, eliminating safety hazards from oblique drilling while maintaining ease of operation
4Manufacturing precision
If the guide member contacts the slat surface during drilling, then drilling guidance is achieved, but the rotation of the guide member marks the slat compromising its esthetic appearance
Solution Approach 1:
The harmful function of the guide member (rotation and marking) is extracted and separated from the useful function (drilling guidance). The guide member is designed to rotate within the guide space without contacting the slat surface, removing the source of surface marking while preserving the guidance function through the confined rotation path
Solution Approach 2:
The guide member's rotation is constrained to occur in a different dimensional space (within the guide space cavity) rather than directly on the slat surface. This dimensional separation allows the guide member to perform its guidance function through rotation while preventing contact marks on the visible slat surface

AI summary
A device assists in drilling a board with a tool having a drill bit, means for rotatably driving the bit, and a guide member—having an outer face with a generally cylindrical shape of revolution about the bit's rotation axis—for guiding the bit in rotation and movement along the bit's longitudinal axis. The device has a rigid body with a flat sole (contact surface). Guide space(s) pass through the rigid body and open onto the sole. Each guide space is delimited laterally toward the outside by a cylindrical internal surface of revolution about a revolution axis orthogonal to the sole's main plane. The internal surface may interact with the guide member and guide the bit in rotation and longitudinal movement along the revolution axis. The internal surface has a radial expansion for stopping, in abutment therewith, the guide member during longitudinal movement of the tool toward the board.
