Optical Scanner Casing with Stacking Engagement Features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional optical scanner casings require precise installation of optical elements, leading to increased transportation costs due to the need for individual packaging and space-efficient stacking during transport to prevent damage and collisions.
Innovation Solution
A casing design with a bottomed box shape and engaging protruding parts on the sidewall, allowing for multi-stage stacking and connection via connection leg parts with engaged holes, enabling efficient space utilization and protection during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If casings are packaged individually to protect optical element installation surfaces, then protection of optical elements is improved, but transportation cost increases due to reduced space utilization
Solution Approach 1:
Multiple casings are merged into a single packaging unit by stacking them together. The casings are equipped with engagement protrusions and engagement recesses that allow them to be mechanically connected and stacked vertically, forming a compact assembly that protects all optical elements while optimizing space utilization during transportation.
2Loss of energy
If casings are stacked during transportation, then space utilization is improved, but risk of collision and damage to optical elements increases
Solution Approach 1:
The casing design incorporates engagement protrusions and engagement recesses that create mechanical interlocking when casings are stacked. This pre-designed connection mechanism prevents unintended movement and collision between stacked casings during transportation, providing protective cushioning before damage can occur.
3Manufacturing precision
If precise optical element installation surfaces are formed inside casings, then optical performance is improved, but manufacturing complexity and transportation requirements increase
Solution Approach 1:
The optical scanning device is segmented into multiple independent casings, each containing a complete optical system. This segmentation allows each casing to be manufactured with precise optical surfaces independently, then stacked and transported as standardized units, reducing overall system complexity while maintaining manufacturing precision.

AI summary
An optical scanning device includes a casing (31). The casing (31) can be stacked in a plurality of stages in a state in which a lid member (32) has been removed, and includes a connection leg part (31e) extending from a predetermined position of the outside surface of a sidewall part (31b) to a lower side of a lower surface of the casing (31), and the connection leg part (31e) is provided with an engaged part (31g) for connection which is engaged with an engaging part (31d) formed at a sidewall part (31b) of another casing (31) when the casing (31) is stacked on an upper side of the other casing (31).
