Technical feasibility

SECTION I: Testing

 

1 Has the R & D result been tested?
YES
NO

 

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?
A working prototype should be built. In fact, the mass production technologies are identical to the laboratory prototyping technologies. For the prototype the same beech raw material could be used, the other components should be tailored to prototype production. The functional prototype would enable the engineers to test both the manufacturing aspects and function performance, as the prototyping technologies and serial production technologies does not differ much. The product does not have moving parts, so the geometrical and electrical conformance has to be tested. The certification focus will be to certify the ingress protection ratings, as the product is a lamp operated by mains electricity. User tests are not required as during the development phase the concept was tested.
1d. What is the time needed for testing?
The timeframe needed for building the prototypes is approximately 2 months. Testing and refining the technical documentation requires an additional 2 moths. This equals 600 FTE hours. The certification procedure cannot be made parallel with the in-house testing, so an extra 1 month is needed on top of the in-house development timeframe.
1e. What is the cost needed for testing?
Calculating with the 600 FTE hours and an average 10 EUR man/hour cost 6,000 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. )
In the final steps of the product development, especially the prototype making can be supported by the development team sufficiently. The development team in this specific case involves the designers and engineers both from the Institute and the cooperating company. The engineering expertise and the know-how for woodwork is available. The prototyping laboratory technologies are givens. The company has contacts to a wide range of manufacturing companies for technical assistance in case.
2b What are the technical issues that need to be tackled for full deployment, if needed?
There are no further technical issues to be tackled. The technical documentation and the BOM is ready, there are only technologization steps left.
2c What additional technical resources are needed for the production of this new product?
As the serial production utilizes similar technologies as the prototype building, those experiences gained throughout the prototyping phase might raise further technical issues. All the components are available on the market, there is a resource for all the raw materials. The manufacturing technologies are common in the sector.

 

2d Overall assessment of the current stage of technical development.
The LED technology modular interior lamp system is a promising concept. The design and the applied technologies are simple from the technical viewpoint. There are no moving parts, the internal electronics are simple as well. The concept is fully developed, no functional risk has been identified. The modular elements of the system are simple, and the lighting part is identical and the same key part has to be used for any compositions. It is an original idea to use bulky wooden (beech) parts as the body of the light source. A working prototype is missing.

SECTION 3: Deployment

3a Define the demands for large scale production in terms of
  • Materials
The core material of the light source is beech. The beech parts carry the light source modules, which are a quarter of a circle glowing rings. The light emitting modules have two main parts, the skeleton and the light emission unit. The optical part consists of two further elements, the LED stripe and the diffuser. The diffuser is made of PLEXIGLAS truLED. There are further minor parts made of rubber, plastic, silicone or steel. Cables are also used.
  • technologies, tools, machineries
The wooden parts are manufactured on CNC milling machine, and colored with stain, then lacquered. The smaller inner parts are made by cutting and other simple machining operations. The diffuser is made by laser cutting. For assembly only gluing is used.
  • Staff effort
For the all of the production steps the expertise of the general functions and personnel from general 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?
The product in the proposal is a modular lighting system which the elements of a variety of combinations can be built. The technology utilized is LED technology. There is only one light emitting module in the catalogue, and all variations of the compositions could be assembled from wooden base elements and the desired number of this identical lighting module. The system enables the customer to tailor the assembly to their taste, customization is realized by the variety in colors and the numbers and combinations of the modular elements. This personalization can be done in advance. The elements are simple to manufacture, the lighting unit is the only critical part. The product is not only feasible but worth to realize.
