Technical feasibility

SECTION I: Testing


1 Has the R & D result been tested?


The following question is replied according to the reply in question 1


If yes


1a In what mode has the result been tested? 

•              Prototype

•              Pilot Application

•              Alpha/BETA testing


1b. Please describe and discuss the testing results


If no:


1c Describe what type of testing does the R&D result need?
The product development is at the stage of technical documentation. A working prototype should be built. Since the proposed product is a security device (a certain kind of a safe), there will be several prototypes needed, because when identifying the class of security different violation methods are applied, so the prototypes will be damaged or ruined. Prototype production normally serves testing purposes, and it is not uncommon that the design is modified on the basis of the prototype experiences.  Besides physical testing the market should be tested with the zero series. There must be certification procedures to be carried out, surely for standard conformity purposes, and maybe for the certification of insurance companies or associations. 


1d. What is the time needed for testing?
For preliminary testing a few prototypes are needed. That is the period of functional tests. The timing of this period is hard to estimate, it depends on how much design changes occur and how many prototypes have to be built. This functional period is approximately 3 month, 480 hours of FTE in duration. The testing period will consist of two additional testing periods; the period of the user tests and the period of tests carried out for certification purposes. These might be parallelized as much as possible, in general there is no logical dependency between the tests. In total the two periods equal 360 FTE hours. The user test period should be scheduled into summertime, since the product is very seasonal. All these have a decisive effect on the whole project plan.
1e. What is the cost needed for testing?
Calculating with the 840 FTE hours and an average 10 EUR man/hour cost 8,400 EUR is the cost of staff. In addition to that the expenses of the certification have to be taken into account, which is approximately 2,000 EUR. The cost of the necessary prototypes are not included in the estimation, note that they might not be negligible.



SECTION 2: Current Stage of Development


2a To what extent does the development team have technical resources for supporting the production of a new product? (Researchers, human resources, hardware, etc. )
The new product needs to be prototyped. Most of the technical development in the prototyping phase could be done in-house, since at the Faculty or globally at the University most of the technologies and experts are available. In the phase of preparation for production the engineers will be able to assist the manufacturing company. The product consists of two characteristic materials; stainless steel and concrete (artificial stone). For both the expertise is available. The laboratory technologies for metalwork are provided, though (plastic) sheet metal forming and advanced cutting steps need to be outsourced.
2b What are the technical issues that need to be tackled for full deployment, if needed?
The locking mechanism should be more comfortable to handle. That is a question of design, the test results and feedbacks will show if there is anything to do. 



2c What additional technical resources are needed for the production of this new product?
For mass production productive sheet metal forming technologies, welding technologies and concrete casting technologies are needed. They are not available at University. The price of processing the required materials into applicable parts does not differ significantly in the region, and as weight is a core solution of the product it is not viable to have the parts manufactured at a remote location and transport it back. Production outside the EU is subject to duty.


2d Overall assessment of the current stage of technical development.
The decisive point for the product is the prototype, which does not exist yet. The working principle is simple, the parts are simple as well. It is expected that no major changes will be needed after the prototype is tested. The technical support is available, the full development of the product is assumed. There will be testing costs arising, which should only be considered as a financial risk factor; failure of the product would be surprising. 




SECTION 3: Deployment

3a Define the demands for large scale production in terms of
  • Materials
The product builds up from concrete (artificial stone) and stainless steel. From concrete approximately 100 kg is needed, from stainless steel sheets (DIN 1.4112 or similar) approximately 3 kg. Originally rubber parts were also incorporated in the design, but during the development it was left out. The concrete is a simple shaped precast piece, the sheet metal parts are either bended and welded, or cold plastic formed. A commercial lock is used to perform the locking function in the locking mechanism.
  • technologies, tools, machineries
In accordance with the two types of materials two main branches of technologies come into question. For the concrete part casting is the technology, if it happen to be made out of artificial stone, the similar technology steps can be followed. The stainless steel parts are manufactured from sheets with cutting, bending, welding, or possibly cold plastic forming. The applied sheet metal processing technologies are not uncommon in the industry. To be able to reach a flexible production cutting steps need to be done in laser cutting machines.
  • Staff effort
Since there is no extreme novelty in the applied materials and technologies, no special expertise is required for the large scale production. The general functions and people from common engineering fields of a production company is sufficient. 






SECTION 4: Overall Assessment


1 What is you overall assessment of the technical feasibility of the research result?
First of all there is no working prototype yet, which does not help to evaluate the technical feasibility of the product. Based on the technical documentation, which contrarily is fully available, the functional viability can be assessed. The design is quite simple, in consequence the primary function is fulfilled at a low level of functional risk. Compared to the other available alternatives the proposed product is a massive, durable piece of artifact. The applied materials and technologies are well-known for the industry, so the realization is not only guaranteed, but there is a price competition expected between the potential manufacturers.
