Router Holding Ring Assembly for Tip-Tool Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing routers with illumination parts require additional components, leading to an increase in the number of parts and potential deterioration of assemblability.
Innovation Solution
A work machine with a motor, rotor, stator, fan, and tip tool, incorporating an illumination part with a light source held by a holding member that integrates with the fan and housing structure to prevent component increase and maintain assemblability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If an illumination part is mounted on the router, then the periphery of the tip tool can be illuminated to improve workability, but the number of components increases
Solution Approach 1:
The holding member that supports the illumination part is integrated with the fan structure. The fan blade serves as both the airflow generation component and the mounting structure for the illumination part, eliminating the need for separate holding components and reducing overall device complexity.
Solution Approach 2:
The fan blade is designed to perform multiple functions: generating airflow for cooling and simultaneously serving as a mounting structure (holding member) for the illumination part. This multi-functionality reduces the total number of components needed in the router.
2Illumination intensity
If an illumination part is mounted on the router, then the periphery of the tip tool can be illuminated, but the assemblability deteriorates
Solution Approach 1:
The holding member is merged with the fan blade structure, creating a unified component that simplifies the assembly process. The illumination part is directly mounted on the fan blade integral structure, reducing the number of assembly steps and improving manufacturability.
3Illumination intensity
If a separate holding member is provided for the illumination part, then the illumination can be positioned correctly, but the device complexity increases
Solution Approach 1:
The holding function is merged into the fan blade structure itself. The fan blade includes integrated features (such as recesses or mounting surfaces) that provide correct positioning for the illumination part, eliminating the need for separate holding members while maintaining proper illumination placement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The configuration allows for peripheral illumination of the tip tool without increasing the number of components and maintains assembly efficiency.
Implementation Method 1
a fan provided on the rotating shaft and arranged on one axial side of the rotating shaft with respect to the rotor and the stator

AI summary
A router includes an illumination part having an LED, and the illumination part is accommodated in an illumination accommodation portion of a holding ring and held by the holding ring. Here, a restriction portion of the holding ring is arranged adjacent to a lower side of a positioning rib of a stator and restricts downward movement of the stator. Thus, the illumination part can be held using the holding ring that restricts the downward movement of the stator. Accordingly, the illumination part can be mounted in the router using a member that holds the illumination part and a member that restricts the downward movement of the stator as a common member. In this manner, the periphery of a tip tool can be illuminated by the illumination part, while preventing an increase in the number of components.
