Electric Tool Setup Switch for Ambient Light Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric tools with ambient lighting modes are difficult to operate, often requiring complex switching mechanisms and leading to unnecessary energy consumption due to automatic shut-off or integration with the motor's operation.
Innovation Solution
An electric tool with a single setup switch that controls both action modes and ambient light mode, allowing sequential and cyclic switching, and featuring automatic shut-off after inactivity or manual override, simplifying operation and reducing energy waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate switch is provided for ambient light mode, then the ambient light can be independently controlled, but the device complexity and wiring complexity increase
Solution Approach 1:
The patent combines the ambient light mode switching function with the existing setup switch used for action mode selection. The setup switch now serves dual purposes: selecting action modes (drilling, driving, impacting) and controlling ambient light mode. This merging eliminates the need for a separate ambient light switch, reducing switch configuration space and wiring complexity while maintaining independent control capability.
Solution Approach 2:
The setup switch is designed with multi-functionality, serving both as an action mode selector and an ambient light mode controller. By making the setup switch universal, the patent reduces the total number of switches needed in the device, simplifying the overall control system architecture and reducing wiring requirements.
2Loss of energy
If the ambient light turns off automatically after a given time, then energy is conserved, but the operation becomes complicated and users may be unaware of the function
Solution Approach 1:
The ambient light mode operates autonomously once activated through the setup switch. The system automatically manages the light duration based on action mode duration, eliminating the need for users to manually control timing or understand complex shutdown mechanisms. The light serves itself by automatically turning off when the associated action mode ends, making the function intuitive and easy to operate.
3Adaptability or versatility
If multiple switches are provided for different modes, then each function can be precisely controlled, but the tool size and cost increase
Solution Approach 1:
The patent merges multiple control functions into the single setup switch, eliminating the need for separate switches for action modes and ambient light control. This consolidation reduces the switch configuration space required in the tool housing, directly contributing to a more compact tool design without sacrificing functional versatility.
Solution Approach 2:
By designing the setup switch with multi-functionality to handle both action mode selection and ambient light control, the patent reduces the total component count in the tool. Fewer switches mean less space dedicated to switch mounting, wiring channels, and associated hardware, thereby reducing overall tool volume and manufacturing cost.

AI summary
The present invention provides an electric tool, which has a plurality of action modes. The electric tool comprises a lighting unit, which irradiates light to the outside of the electric tool, wherein the lighting unit comprises a working light mode that is activated when the electric motor acts and an ambient light mode that is activated when the electric motor does not act. A setup switch, which is configured to switch the settings of the plurality of action modes, and is further configured to activate and/or disable the ambient light mode of the lighting unit. Thus, the turning on and turning off the ambient light mode of the electric tool of the present invention are realized by a shared setup switch configured to switch action modes, without the need to separately provide another switch.
