Portable Pod Repair Unit With Deployable Bubble Enclosure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for repairing pods, especially laser designation pods, are inefficient and costly due to the need for white room facilities, which are not universally available, leading to high costs and long repair times, and the expense of spare parts.
Innovation Solution
A transportable repair unit comprising a casing with a deployable bubble and gas supply system that maintains a sealed, controlled environment, allowing for on-site repairs without contaminating the interior space, using a bubble with elastic tubes for operator hand access and a pressure switch to control gas flow, enabling the use of nitrogen for a clean and controlled atmosphere.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a white room is used for pod repair, then the repair environment is clean and controlled, but the cost and time increase significantly
Solution Approach 1:
The white room functionality is segmented into a portable bubble enclosure that can be deployed at the repair site, separating the clean environment requirement from the fixed facility requirement. This allows the repair to occur on-site without returning to manufacturer facilities.
Solution Approach 2:
The bubble enclosure transitions from a static white room concept to a dynamic, deployable structure that can be inflated and deflated as needed. This dynamic deployment reduces setup time and allows rapid establishment of a controlled environment at the repair location.
2Reliability
If a white room is used for pod repair, then the repair environment is clean and controlled, but the cost increases due to facility requirements
Solution Approach 1:
The bubble enclosure uses a simple, inexpensive membrane structure compared to permanent white room facilities. The bubble can be deployed, used for repair, and then deflated/stored, avoiding the need for expensive permanent facility construction and maintenance.
Solution Approach 2:
The white room functionality is achieved using a flexible bubble membrane instead of rigid, expensive facility walls. This thin-film approach provides the necessary environmental control at a fraction of the cost of traditional white room construction.
3Ease of operation
If the bubble is deployed for repair, then operator access is enabled, but contamination risk increases
Solution Approach 1:
The bubble membrane acts as an intermediary barrier between the operator's external environment and the internal repair space. This flexible barrier allows hand access through tubes while maintaining contamination protection, serving as a mediator that enables operation without direct exposure.
4Adaptability or versatility
If the repair unit is made transportable, then on-site repair is enabled, but the complexity of maintaining controlled environment increases
Solution Approach 1:
The essential white room functionality is extracted from complex permanent facility systems and condensed into a simple, transportable bubble enclosure. This extraction removes unnecessary complexity while retaining the core function of providing a controlled environment for repair work.
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
This solution allows for efficient and cost-effective on-site repairs of pods by creating a portable, controlled environment that minimizes contamination and reduces repair duration, saving time and money by eliminating the need for returning pods to manufacturer facilities.
Implementation Method 1
a gas supply device (22) which is capable of switching the bubble (18) from the retracted state into the deployed state
Implementation Method 2
the repair unit comprises a pressure switch connected on the one hand to the interior of the casing and on the other hand to the gas supply device, the pressure switch being capable of measuring the differential pressure within the interior of the bubble
Implementation Method 3
the gas supply device is a motorised fan blower with filter that is capable of generating an air flow, the particle concentration of which being controlled
Implementation Method 4
the gas supply device comprises one or more bottles of nitrogen that is/are capable of generating a flow of nitrogen, the particle concentration of which being controlled
Implementation Method 5
each tube comprises elastics, the elastics being capable of tightly gripping the arm of an operator when the hands of the said operator are introduced into the bubble
