Power Tool Illuminator Lighting Mode Selector Switch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power tools with built-in illuminators continue to consume unnecessary electric power after the main switch is turned off, as the illuminator remains on for a predetermined time period, leading to inefficient energy use in various work environments.
Innovation Solution
A power tool with a lighting mode selector switch that allows users to choose between continuous illumination, no illumination, or adjustable illumination periods, enabling the illuminator to be turned on or off independently of the main switch, thereby preventing unnecessary power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the illuminator is set to remain on for a predetermined time period after the main switch is turned off, then the working area can be illuminated after work is completed, but electric power is needlessly consumed
Solution Approach 1:
The illuminator's operation mode is made dynamic and adjustable through the lighting mode selector switch, allowing users to switch between different lighting modes (first lighting mode with predetermined time period illumination, second lighting mode with immediate shutdown, third lighting mode with manual control) based on actual work environment needs, thereby optimizing power consumption while maintaining operational convenience
Solution Approach 2:
The system changes the operational parameters of the illuminator by introducing a selector switch that modifies the timing and control characteristics of the illuminator, enabling parameter adjustment between automatic delayed shutdown and immediate shutdown modes to resolve the contradiction between convenience and power consumption
2Illumination intensity
If the illuminator is turned on continuously after the main switch is turned off, then the working area remains illuminated, but energy is wasted in environments where lighting is not needed
Solution Approach 1:
The illuminator system transitions from a static automatic shutdown mode to a dynamic multi-mode system where users can select between continuous illumination (first lighting mode), immediate shutdown (second lighting mode), or manual control (third lighting mode), allowing the illumination function to adapt to varying environmental lighting conditions and work requirements
Solution Approach 2:
The lighting mode selector switch provides multi-functionality by enabling the same illuminator to serve different purposes in different contexts: automatic illumination for dark environments, immediate shutdown for well-lit environments, and manual control for variable conditions, making the system universally applicable to various work scenarios

AI summary
A power tool of the present teachings comprises a prime mover that drives a tool, a main switch that causes the prime mover to operate when the main switch is turned on and causes the prime mover to stop operating when the main switch is turned off, an illuminator that lights a working area of the tool, and a lighting mode selector switch for switching the lighting mode of the illuminator between a plurality of lighting modes which include a first lighting mode and a second lighting mode. When the first lighting mode is selected, the illuminator will be turned on for a first predetermined period from the point at which the main switch is turned off. When the second lighting mode is selected, the illuminator will not be turned on during the first predetermined period from the point at which the main switch is turned off.
