Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media supply systems for laboratories and classrooms are costly, require significant space, and lack flexibility in adapting to changing laboratory activities, especially when media supply is provided from the ceiling.
Innovation Solution
A mobile media supply device with a wheeled body containing a media store, media withdrawal connections, a blocking device, a mobility blocking device, and a control device that manages the state of the blocking device and mobility using contactless release mechanisms, ensuring safe and flexible media distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a ceiling-mounted media supply system is installed, then media can be supplied to workstations without floor connections, but the system requires significant space and infrastructure investment
Solution Approach 1:
The patent transforms the traditional stationary ceiling-mounted media supply system into a mobile version that can be freely positioned and moved. The mobile media supply device includes a body mounted on wheels, allowing it to be dynamically repositioned according to changing laboratory needs, thereby eliminating the need for extensive fixed infrastructure while maintaining media supply flexibility.
Solution Approach 2:
The invention extracts the essential media supply function from the fixed ceiling infrastructure and consolidates it into a self-contained mobile unit. The media store, withdrawal connections, and control mechanisms are integrated into the mobile body, separating the media supply capability from the building's fixed architecture and reducing space requirements.
2Adaptability or versatility
If a mobile media supply device is implemented, then flexibility and adaptability are improved, but safety risks increase due to mobility
Solution Approach 1:
The patent incorporates a control device that monitors the state of the media blocking device and automatically controls the mobility blocking device. When the media blocking device is activated to prevent media withdrawal, the control device automatically engages the mobility blocking device to prevent movement, creating a feedback loop that ensures safety through coordinated operation of blocking functions.
Solution Approach 2:
The system applies preliminary anti-action by using the mobility blocking device to prevent movement before any unsafe conditions can arise. When the media blocking device is in the blocked state, the control device proactively engages the mobility blocking device to constrain the device, preventing any potential unsafe movement or positioning before it can occur.
3Ease of operation
If media withdrawal connections are made accessible, then ease of media access is improved, but unauthorized access and damage risks increase
Solution Approach 1:
The patent introduces a control device as an intermediary between the media store and the media withdrawal connections. This control device manages the media blocking device, which acts as a mediator that can be selectively activated to prevent media withdrawal. The control device serves as an intermediary layer that authorizes and regulates access, preventing unauthorized or damaged access while maintaining ease of legitimate media withdrawal.
