Environment Forming Device with Below-Sample Slide Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The extension members on the sliding door of conventional environment forming devices hinder access to the sample when the door is pulled out for work such as connecting wires to a printed circuit board.
Innovation Solution
The environment forming device includes a slide mechanism with an elongated extension member positioned below the reception portion on the door, allowing the extension member to be slidably held by a holding portion on the device body, ensuring it does not obstruct access to the sample.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If extension members are arranged at left and right ends of the door at the same height as the sample stage, then the door structure is stable and sliding is smooth, but the extension members hinder access to the sample from the side
Solution Approach 1:
The extension member is repositioned from a horizontal arrangement at the same height as the sample stage to a vertical arrangement below the sample stage. This dimensional change in positioning eliminates the obstruction to side access while preserving the sliding function, as the extension member now occupies a different spatial zone that does not interfere with sample accessibility.
2Ease of operation
If the extension member is positioned below the reception portion, then side access to the sample is unobstructed, but the door support stability may be affected
Solution Approach 1:
The holding portion acts as an intermediary structure that connects the extension member to the device body. This intermediary arrangement allows the extension member to be positioned below the sample stage for unobstructed access while the holding portion provides the necessary structural support and stability, transferring loads appropriately between the door assembly and the device body.
3Strength
If the extension member has a predetermined width in the up-down direction, then the sliding mechanism is robust, but it creates obstruction when accessing the sample from the side
Solution Approach 1:
The extension member's functional role is maintained through its connection to the door and sliding mechanism, but its vertical positioning is changed to below the sample stage. This repositioning in the vertical dimension allows the member to retain its structural robustness while eliminating the horizontal obstruction it previously caused during sample access operations.

AI summary
An environment forming device includes: a device body having a space for generating a predetermined environment; a door; and a slide mechanism that makes the door slidable with respect to the device body so as to open and close the space. The slide mechanism includes an extension member having an elongated shape fixed to the door, and a holding portion that is arranged on the device body and slidably holds the extension member. A reception portion for a sample is arranged on the door such that the sample is arranged in the space in a state where the door closes the space. The extension member is positioned below the reception portion.
