Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for overhead drilling are inefficient, inaccurate, and pose significant physical strain and injury risks to workers due to the need for heavy machinery and close proximity to the drilling surface, leading to fatigue, soreness, and increased risk of eye and other injuries from flying debris.
Innovation Solution
A drill assist device with a telescopically coupled design, utilizing a pull-down handle and wire rope cable mechanism to apply constant force, allowing for ergonomic operation and reduced worker proximity to the drilling surface, eliminating the need for pneumatic or electric mechanisms and enabling easy adjustment and transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If heavy machinery is used for overhead drilling, then drilling stability and force are improved, but worker physical strain and injury risk increase
Solution Approach 1:
The patent introduces an overhead drill support device as an intermediary between the worker and the drill. The device includes a support structure with adjustable arms that hold the drill, allowing the worker to apply drilling force through a mechanical advantage system rather than directly holding the heavy drill overhead. This mediator reduces the physical strain on workers while maintaining drilling stability and force.
Solution Approach 2:
The support device incorporates counterbalancing mechanisms where the adjustable arms and support structure are designed to offset the weight of the drill. This allows the drill to be held overhead without requiring the worker to continuously exert force to counteract gravity, thereby reducing fatigue and injury risk while maintaining drilling capability.
2Stability of the object's composition
If heavy machinery is used for overhead drilling, then drilling stability is improved, but worker fatigue and operational efficiency worsen
Solution Approach 1:
The support device acts as a stable intermediary structure that holds the drill in position overhead. The adjustable arms and support mechanism provide structural stability, allowing the drill to remain steady during operation without requiring the worker to continuously stabilize heavy equipment, thereby improving both stability and efficiency.
Solution Approach 2:
The device incorporates adjustable and movable components that allow the support structure to adapt to different drilling positions and depths. The adjustable arms can be repositioned during operation, providing dynamic stability rather than rigid fixed positioning, which improves both drilling stability and worker efficiency.
3Manufacturing precision
If close proximity to drilling surface is maintained, then drilling precision is improved, but exposure to flying debris and injury risk increases
Solution Approach 1:
The support device serves as an intermediary that positions the drill at the precise drilling location while keeping the worker's hands and body at a safe distance from the drilling surface. The mechanical advantage system allows the worker to control drill positioning and depth from a safer position, maintaining drilling accuracy while reducing exposure to flying debris.
4Device complexity
If manual operation is used, then device complexity is reduced, but operational force requirement increases
Solution Approach 1:
The device is segmented into distinct functional components: a support structure, adjustable arms, and a mechanical advantage system. This segmentation allows each component to perform a specific function with simple mechanics, avoiding complex integrated systems while distributing the force requirements across multiple simple mechanical elements that provide leverage.

Function Achieved in This Case
The device reduces worker fatigue and injury risk, increases drilling efficiency and accuracy, and enhances productivity by allowing for comfortable operation and safer working conditions, as demonstrated in a tunnel construction project where workers significantly increased hole drilling rates with reduced physical strain.
Implementation Method 1

AI summary
A drill assist device comprising a first segment and a second segment telescopically coupled to one another, where the first segment further contains a gas strut. A pull down handle is configured to connect the first segment and the second segment and enable compression of the drill assist device when a worker applies pressure to the pull down handle. This compression is further assisted by at least one wire rope cable that is affixed to both the pull down handle and the second segment and may be secured via one or more wire rope clamps. The wire rope claims maybe tightened or released to extend or retract the second segment to achieve the desired height of the drill assist device.
