Portable Drilling Machines TRIZ Cases
- Drill Suction Head Duct Layout for Lower Air Resistance
A secondary intake port merges with the main suction flow to cut air resistance, improve dust capture, and extend vacuum runtime.
- Rotary Tool Guide for Accurate Angled and Depth-Controlled Drilling
A surface-contacting guide shaft holds a drill at a set angle and limits depth, improving repeatable angled drilling without bulky rigs.
- Core Drill Motor Layout for High Torque and Lower Heat
A larger stator and dual battery layout help this core drill deliver high torque with less motor heat and better weight balance.
- Core Drill Controller Cooling Layout for Better Handling
Placing the controller between the motor and grip improves airflow cooling while aligning the grip with the axis enhances core drill balance.
- Dust Extractor Airflow Monitoring for Clog and Fill Detection
Airflow and tool-parameter sensing detects clogs or a full dust box early, enabling alerts and control actions that sustain collection efficiency.
- Angle Drill Housing Materials for High Torque at Lower Weight
Composite transmission box materials cut angle drill weight below 6 kg while preserving high torque and a power-to-weight ratio of at least 220 W/kg.
- Bell-Shaped Drill Dust Collector for Multi-Angle Particle Containment
A flexible bell housing with an adjustable ring and suction channels captures drilling dust in vertical or horizontal use while preserving visibility.
- Flexible Drill Bit Structure for Angled Hip Joint Drilling
A segmented flexible drill bit and angled guide preserve torque and alignment for precise bone drilling through curved hip joint access.
- Angular Drill Cushion Attachment for Hand Force and Surface Protection
A removable cushion attachment absorbs hand force on angular drills and prevents housing impacts from damaging fabricated surfaces.
