Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing optical scanning devices do not fully utilize the fixed frame, leading to underutilization and potential manufacturing inefficiencies, as it only serves as a support without additional functionality.

Innovation Solution

Incorporating inspection patterns and other features on the fixed frame of the optical scanning device, such as recognition, identification, and management patterns, which are formed during the manufacturing process without increasing costs, allowing for effective use of the fixed frame and enhancing manufacturing efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the fixed frame is used only as a support structure, then the device structure is simple, but the utilization of the fixed frame is low and manufacturing efficiency is reduced

Engineering Contradiction:

Improveutilization of fixed frameVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fixed frame is designed to serve multiple functions: it provides structural support while also carrying inspection patterns, recognition patterns, identification patterns, and management patterns. This multi-functional design increases the utilization of the fixed frame without requiring additional separate components, thereby improving adaptability while maintaining structural simplicity

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple functional elements (inspection patterns, recognition patterns, identification patterns, management patterns) are merged into the fixed frame structure itself. By combining these functions into a single integrated component rather than separate parts, the patent achieves better utilization of the fixed frame while avoiding increased device complexity

Inventive Principle:

Principle #5Merging (Combining)

2Productivity

If inspection patterns are added to the fixed frame, then manufacturing efficiency is improved, but the device complexity increases

Engineering Contradiction:

Improvemanufacturing efficiencyVSAvoiddevice structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The inspection patterns are merged into the fixed frame during the same manufacturing process. By forming the patterns as an integral part of the fixed frame rather than adding them as separate components, the patent improves manufacturing efficiency through process integration while avoiding the complexity increase that would result from additional assembly steps

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The inspection patterns are formed on the fixed frame during the manufacturing process itself, before the device is completed and shipped. This preliminary formation of functional elements during manufacturing improves efficiency by eliminating post-manufacturing inspection steps while not increasing the final device complexity

Inventive Principle:

Principle #10Preliminary action

AI summary

An optical scanning device includes a mirror that includes a mirror reflection surface, a driving part that drives the mirror, and a fixed frame that supports the mirror via the driving part. The fixed frame includes one or more inspection patterns that are formed while at least one of the mirror and the driving part is formed.
