A detail to the beginner designer.

Task: Designing an interior magnetic lock with forced retraction of the magnetic slider.Basic analog (reference for dimensions): AGB TouchCritical difference from the analog (Essence of the mechanics):In the original AGB Touch, the slider with the magnet is retracted only by the force of the door's locking/pulling. In the developed lock, it is necessary to implement forced mechanical retraction of the magnetic slider into the housing with a slight pull of the door handle towards oneself.Mechanism operation logic:In the initial position (handle in the initial position), the slider with the neodymium magnet is pushed forward by a built-in spring (towards the strike plate of the frame).When pulling the door handle towards oneself, the internal catch (lever finger) should slightly engage the magnetic slider and forcibly pull it inside the lock housing, completely hiding the magnet in the end.Upon releasing the handle, the return spring returns the magnetic slider to the initial (extended) position.A locking device should be provided to block the movement of the door handle towards oneself. Similar to a WC lock.Output requirements: Assembly in STEP or IGES format, suitable for test 3D printing on an SLA/FDM printer.

Develop for two devices: general assembly drawing of the metal frame; general assembly drawing of the service platforms; detailed drawings of ladders; detailed drawings of railings; detailed drawings of equipment supports; specification of metal products; St3 or 09g2s As a result of the design, it is necessary to obtain: 3D model of the frame. General assembly drawing. Specification of metal products. Calculation of the load-bearing capacity of the structure (will be a plus).

Development of a mechanism for alternating the flipping of plastic cupsProject Goal It is necessary to develop only the mechanism for flipping plastic cups "every other one" for an automatic production line. The device must ensure the following sequence: 1st cup — without flipping (0°) 2nd cup — flip 180° 3rd — without flipping 4th — flip 180° and so on. As a result, the output should produce the sequence: 0° → 180° → 0° → 180° → ...What is already available The cups move along the conveyor in a single row. Before the mechanism, all cups have the same orientation (lid up). Only the flipping unit needs to be developed.Proposed Operating Principle The following scheme is considered: A dividing screw synchronizes the flow of cups. All cups gradually rotate to the position of 90°. Then, the cam mechanism acts only on every second cup. Every second cup returns from the position of 90° back to 0°. The others continue rotating to 180°. As a result, we get: 0° 180° 0° 180° If the performer offers a simpler, more reliable, or more technological solution — we are ready to consider it.Requirements1. Develop a complete 3D model in SolidWorks It is necessary to model: dividing screw; flipping mechanism; cams; guides; shafts; mountings; all necessary parts.2. Perform kinematic verification It is necessary to ensure that: the mechanism operates without jamming; there are no intersections of parts; the cups are flipped correctly; the mechanism is suitable for manufacturing.3. Conduct Simulation / Motion Study It is necessary to perform an animation of the mechanism's operation in SolidWorks Motion. It should be visible: the movement of the cups; the rotation of parts; the sequence of flipping every second cup.Work Result The performer must provide: source files SolidWorks (*.SLDPRT, *.SLDASM); assembly; Motion Study; animation video; STEP file of the assembly; drawings of the main parts.

It is necessary to make an analysis of the project (drawing) of the advertising installation with a description. Dimensions: Width: up to 2.25 m Height: up to 2 m Depth: up to 1 m

packaging solutions / flexible packaging). It is necessary to develop a prototype of a two-chamber packaging for a food product. Idea: The packaging consists of two separate chambers with different ingredients. Upon strong compression of the packaging, the internal partition should controllably break, after which the contents of the two chambers mix. The user then shakes the packaging and opens it for consumption. Requirements: Develop the packaging design. Select materials and production technology. Create a working prototype. Prepare the packaging for mass production. If necessary, assist in finding a manufacturer. Preferred experience: Flexible packaging (sachet, doypack, flow-pack, etc.). Development of custom packaging solutions. Food products or dietary supplements. Understanding of film welding technologies and creating breakable internal partitions. Example concept — BOOMSHOT packaging (in the photo): two chambers that mix upon compression.
