Cell Device Door with Light Blocking Section for Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing injection molding systems lack effective safety measures to prevent users from inadvertently operating the system during its operation, potentially leading to accidents.
Innovation Solution
A cell device with a housing that includes a door with a light blocking section and a light transmitting section, where the door is designed to overlap the operation section when closed, ensuring it is hidden from view and preventing accidental operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operation section is arranged outside the injection molding machine, then the ease of operation is improved, but the safety is worsened due to potential erroneous operation by users
Solution Approach 1:
The door is designed with differentiated regions: a light blocking section that obscures the operation section when closed, and a light transmitting section that allows visibility of the movable device. This local differentiation in optical properties enables simultaneous safety (hiding controls) and operational awareness (seeing device status).
2Reliability
If the operation section is arranged inside the accommodation space, then the safety is improved by preventing accidental operation, but the ease of operation is worsened due to reduced accessibility
Solution Approach 1:
The door transitions between open and closed states dynamically. When closed during operation, it provides safety by obscuring the operation section. When opened for maintenance or setup, it provides full accessibility. This dynamic state change resolves the contradiction between safety and accessibility.
3Reliability
If a light blocking section is added to the door, then the safety is improved by hiding the operation section, but the device complexity is worsened
Solution Approach 1:
The door serves multiple functions: it provides physical access control to the accommodation space, incorporates a light blocking section to hide the operation section for safety, and includes a light transmitting section to allow visibility of the movable device. This multi-functionality reduces the need for separate components and minimizes overall system complexity.
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 solution effectively enhances safety by ensuring the operation section is not visible during the device's operation, reducing the risk of accidental operation and improving user focus on the task at hand.
Implementation Method 1
the door includes a light blocking section having a light blocking property and a light transmitting section having light transmissivity

AI summary
A cell device includes a housing including an accommodation space and a door connected to the accommodation space, a movable device arranged in the accommodation space, and an operation section arranged in the accommodation space and configured to operate the movable device, wherein the door includes a light blocking section having a light blocking property and a light transmitting section having light transmissivity and in a state where the door is closed, the light blocking section overlaps with the operation section when the housing is viewed from a door side along a normal direction of the door. The operation section is arranged in the accommodation space so as to face the door and is arranged further to the door side than is the movable device.
