Right-Angle Drill Adapter for Heavy-Duty Drilling in Tight Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing right-angle drills are limited in size and horsepower, and have restricted offset distances, making it difficult to use heavy-duty industrial drills in confined or angled locations for drilling holes.
Innovation Solution
A right-angle drill adapter with a main body, input and output shafts, bearing support fasteners, roller support fasteners, a handle support shaft, a light switch, parallel and series connected batteries powering a light-emitting diode, and a quick-release chuck surrounded by ball bearings, allowing for bidirectional rotation and reduced clearance length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing right-angle drills are used, then drilling in confined locations is possible, but the drill size and horsepower are limited
Solution Approach 1:
The patent introduces a right-angle adapter as an intermediary device between the drill and the workpiece. This adapter has a hollow body that receives the drill, with the drill shaft extending through the adapter. The adapter creates a right-angle offset while transmitting the drill's rotational force to the bit, enabling heavy-duty drills to access confined locations without direct contact between the drill body and the workpiece area
2Ease of operation
If existing right-angle adapters are used, then some access to angled locations is achieved, but the offset distance is limited
Solution Approach 1:
The patent incorporates a telescoping mechanism within the adapter body that allows the offset distance to be dynamically adjusted. The telescoping sections can extend or retract based on the specific drilling requirements, enabling the adapter to accommodate various offset distances while maintaining the right-angle configuration for accessing confined and angled locations
3Power
If heavy-duty industrial drills are used, then high horsepower is available, but they cannot be adapted to drill in confined locations with large offset distances
Solution Approach 1:
The adapter design incorporates universal features including a telescoping mechanism for variable offset distances, a quick-release chuck for rapid bit changes, and a robust structure that accommodates heavy-duty drills. These multi-functional elements enable the adapter to work with various drill types and configurations, providing both high power transmission capability and adaptability to different confined location requirements

AI summary
A drill adapter is fashioned to enable right-angle drilling, incorporating an input drive, an input bearing, an output bearing, and an output drive. The input drive is capable of receiving a hand-held driving tool and the output drive is capable of engaging a fastener. The input bearing, which is driven by the input drive, is operably attached to the output bearing, which drives the output drive. The adapter incorporates a housing to protect the bearings and also has a handle to enable an operator to grasp.
