Core Drill Parallel-Axis Layout for Cordless Stand Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mains-operated core drills are inconvenient to handle due to wiring hazards, limited mobility, and safety risks, especially in construction sites where electrical energy is not readily available, and their design often compromises rigidity and accessibility when used with drill stands.
Innovation Solution
A power tool with parallel output and motor axes, utilizing exchangeable energy supply devices such as batteries or mains adapters, allowing flexible operation without cords, improved component protection, and a drill stand interface positioned for enhanced stability and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If mains-operated core drills are used to ensure continuous energy supply, then power availability is improved, but safety risks and handling convenience deteriorate due to wiring hazards and power cord damage
Solution Approach 1:
The patent extracts the power cord and mains connection interface from the drill system, replacing them with a battery-powered design. This removes the harmful wiring elements that caused safety risks while maintaining continuous operation capability through rechargeable batteries
Solution Approach 2:
The patent replaces the electrical connection system (power cords, plugs, mains interfaces) with a mechanical battery system. The battery housing contains the energy supply without requiring external electrical connections, eliminating the mechanical hazards of cords and plugs
2Use of energy by moving object
If mains-operated core drills are used to ensure continuous energy supply, then power availability is improved, but mobility and flexibility deteriorate due to power cord constraints
Solution Approach 1:
The patent removes the power cord and mains connection requirements from the system, allowing the drill to operate independently without external electrical infrastructure. The battery housing provides portable energy supply for unrestricted mobility
Solution Approach 2:
The patent transitions from a static power connection system (fixed mains supply requiring cord extension) to a dynamic portable energy system (rechargeable batteries that move with the tool), enabling operation in locations without electrical outlets
3Ease of operation
If drill stand interface is positioned on the underside of the drill to improve accessibility, then ease of attachment is improved, but system rigidity and stability deteriorate due to increased distance from the drill stand
Solution Approach 1:
The patent repositions the drill stand interface from the traditional underside location to the lateral side of the housing. This spatial reconfiguration maintains easy accessibility while reducing the distance to the drill stand, thereby improving system rigidity and stability
4Adaptability or versatility
If battery is positioned in the housing to provide portable energy supply, then flexibility and safety are improved, but distance to drill stand interface increases, reducing system rigidity
Solution Approach 1:
The patent positions the drill stand interface laterally on the housing rather than on the underside, creating a more favorable geometric arrangement that simultaneously accommodates the battery housing and minimizes distance to the drill stand, thereby maintaining both flexibility and rigidity
