Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power tools lack efficient and versatile lighting systems that provide adequate illumination for workspaces, are prone to damage, and complicate assembly due to complex electrical connections.
Innovation Solution
A hand-held power tool with a housing assembly, motive source, and a nosepiece supporting chip-on-board (COB) LEDs, featuring a trigger for controlling functions like brightness and activation, a protective lens, and a secure electrical connection system using mating connectors to simplify assembly and prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex electrical connections are used to provide power to lighting components, then the lighting system can be more versatile and controllable, but the assembly process becomes more complicated and the risk of damage increases
Solution Approach 1:
The electrical connection system is segmented into modular male and female connectors that can be independently assembled. The male connector with protruding electrical contacts and the female connector with corresponding receptacles allow for separate handling and assembly, reducing the complexity of wiring while maintaining versatile control capabilities through the modular interface.
2Ease of repair
If lighting components are exposed to provide easy access and visibility, then maintenance becomes easier, but the components become prone to contamination and damage
Solution Approach 1:
The lighting components are nested within the protective housing structure. The male and female connectors are housed within protective bores, and the electrical contacts are enclosed within the connector bodies. This nested arrangement protects the lighting components from contamination while maintaining accessibility through the removable connector design.
3Volume of moving object
If the lighting system is integrated into the nosepiece, then the overall structure becomes more compact, but the assembly and disassembly of the nosepiece becomes more complex
Solution Approach 1:
The male electrical connector is merged with the nosepiece as an integral component, while the female connector is integrated into the housing assembly. This merging approach allows the lighting system to be compactly integrated into the nosepiece structure without requiring separate mounting brackets or additional assembly steps, as the connectors are built-in rather than add-on components.

AI summary
An illustrative embodiment of the present disclosure provides hand-held power tool which includes a housing, a motor, and an output spindle. The housing supports a motor having a rotor configured to rotate when the motor is supplied with power. The output spindle protrudes from an output end of the housing, and is functionally coupled to the rotor such that the output spindle rotates in response to a rotation of the rotor. The housing also supports at least one electrical accessory that is connectable to an external power connector located on the housing.
