Solution Overview

Problem

Existing router installation methods on router tables are complex and inefficient, often resulting in low precision due to the difficulty in ensuring the router is flush with the table top, leading to potential wood jamming during machining.

Innovation Solution

A power device with a detachable mounting plate and table, featuring a positioning assembly for pre-positioning and a locking assembly that includes a movable piece and locking piece, along with an auxiliary locking assembly, to simplify and secure the router's installation, ensuring it is flush with the table top without manual support, thus enhancing installation efficiency and precision.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple screws are used to directly fix the router on the router table, then the connection is secure, but the installation process becomes complicated and efficiency decreases

Engineering Contradiction:
Improveconnection securityVSAvoidinstallation efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The connection system is divided into two functional modules: a positioning assembly with positioning pieces that provide preliminary alignment, and a locking assembly with movable pieces and locking pieces that secure the connection. This segmentation allows the positioning function and locking function to be performed separately, simplifying the overall installation process while maintaining security.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The positioning pieces are designed to perform preliminary positioning of the router on the router table before the locking operation. The positioning space formed between positioning pieces and the table top pre-aligns the router, so that when the locking assembly is engaged, the router is already in the correct position, eliminating the need for manual alignment and adjusting during the locking process.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If multiple screws are used to directly fix the router on the router table, then the connection is secure, but the installation process becomes complicated

Engineering Contradiction:
Improveconnection securityVSAvoidconnection process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The positioning function and locking function are merged into an integrated connection assembly that works as a unified system. The positioning pieces and locking pieces are coordinated so that the positioning space and locking mechanism function together, reducing the number of separate components and operations needed compared to using multiple screws independently.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The positioning pieces automatically perform the alignment function when the router is placed on the router table, without requiring manual intervention. The positioning space passively guides the router into the correct position, and the locking assembly then simply needs to be engaged to secure the connection, making the system self-aligning and reducing operational complexity.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If manual support is required during installation, then positioning can be adjusted, but the installation process becomes time-consuming and less efficient

Engineering Contradiction:
Improveflushness with table topVSAvoidinstallation speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The positioning pieces are designed to automatically perform the positioning function without requiring manual support or adjustment. When the router is placed on the router table, the positioning space formed between the positioning pieces and the table top automatically aligns the router body with the table top surface, ensuring flushness without human intervention.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The positioning pieces perform the alignment action in advance, before the locking operation begins. The positioning space pre-positions the router in the correct location and orientation, so that when the locking assembly is engaged, no further adjustment is needed. This preliminary positioning action eliminates the need for manual support during installation.

Inventive Principle:
Principle #10Preliminary action

4Ease of operation

If the router is not precisely positioned, then installation is simpler, but the router is not flush with the table top causing wood jamming

Engineering Contradiction:
Improveinstallation simplicityVSAvoidflushness with table top
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The positioning pieces perform the precise positioning action in advance, before the locking operation. The positioning space automatically aligns the router body with the table top surface when the router is placed on the table, ensuring flushness without requiring complex manual adjustment procedures. This preliminary positioning makes the installation both simple and precise.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The positioning pieces automatically perform the alignment function without requiring manual intervention or complex adjustment procedures. The positioning space passively guides the router into the correct position, ensuring the router body is flush with the table top surface. This self-positioning mechanism maintains precision while keeping the operation simple.

Inventive Principle:
Principle #25Self-service

AI summary

A power device includes a power tool, a mounting plate, a mounting table, a positioning assembly, and a locking assembly. The positioning assembly includes a positioning piece. A positioning space is formed between the positioning piece and the mounting table. An end of the mounting plate is enabled to be inserted into the positioning space so that the mounting plate is pre-positioned. The locking assembly includes a movable piece and a locking piece. The movable piece includes a support position where the mounting plate is supported and an unlocked position where support for the mounting plate is released. The locking piece fixes at least the mounting plate to the mounting table.
