Contraption

EVENT DESCRIPTION:-

Contraption is a chain of different ‘energy conversion’ steps, in which one step triggers the next one leading to completion of final task. In this event participants are asked to make a Contraption system which will hit a skittle arrangement.

Prizes worth INR 30000

Date: 4th March 2018

Time: 10AM to 5PM

Venue: GJCC Entrance

 

FORMAT:-

  • This event consists of two rounds.

  • Round 1 - Participants will be given a Questionnaire with a set of questions on mechanisms and chain reactions, based on the scores in first round few of them will be shortlsted to the next round. 

  • Round 2:

  • The participants have to hit the pillars of different heights placed in rows using a multi-shooting system.

  • The system should have a minimum of 10 steps.

  • A step is an action that results into another action and continues to the final aim. Each step should have energy conversion from one form of energy to another.

  • Parallel steps will be awarded more marks. A parallel step is an action which initiates two or more steps at the same time.

  • There should be at least four different energy conversions (eg. potential to kinetic, electrical to mechanical etc.) and rest of the contraptions (steps) can be of any type.

  • Participants can start the chain reaction automatically or manually.

  • Participants are allowed to make a maximum of 2 checkpoints in their machine according to their convenience, but the marks will deducted accordingly.

  • Participants are allowed to use fire and water in their Contraption system. Points will be awarded accordingly.

  • Participants will be provided with a power supply of 230V-50Hz if needed.

At the end participants are asked to hit the pillar arrangement. It will be like a skittle arrangement(Max. 3 Rows) but it will have pillars of gradually increasing heights. All the pillars will have different weights and would be gradually increasing in each column. Points will be awarded according to the number of fallen pillars.

JUDGING CRITERIA :-

  • Direct steps and parallel steps in the Contraption will be awarded 10 and 20 points respectively.

  • Energy conservations involved in the system will be awarded 30 points.

  • Automatic initiation of the steps will be awarded an additional 15 points.

  • Robustness of contraption will add to the score.

  • Number of trails and usage of check points used will lead to deduction of points.

  • If gradients are not used then 20 points will be deducted.

  • Design of the shooting system will be considered for points.

  • Participants are allowed to make a maximum of 2 checkpoints.

  • 1) No checkpoint – 10 additional points will be given.

  • 2) One checkpoint – 5 additional points will be given.

  • 3) Two checkpoints – No points will be given.

  • 4) Pillars of Last Row: 15 points per pillar

  • 5. Pillars of First Row: 10 points per pillar

  • 6. Pillars of Middle Row:20 points per pillar

  • *Checkpoints are the specified places in the contraption system, From where reactions can be restarted.

  • *Checkpoints are provided to restart incase the task fails. But not to split the system into two parts.

PROBLEM STATEMENT:-

To design a contraption system which will fulfill all the requirements mentioned in the format of the event.

 

F.A.Q:-

Q1. Does an abstract need to be submitted ?

Ans. No

 Q2. What forms of energy can be involved in the contraption system?

Ans. The participants can make use of kinetic, potential, electrical, magnetic, elastic, thermal energies etc. Use of chemicals is strictly prohibited and hence no form of chemical energy is to be used.

 Q3. Will electricity supply be provided?

Ans. Yes, but only for charging batteries. Participants have to bring their own batteries and their respective chargers if electrical energy is involved in the contraption system.

 Q4. What will happen if a team’s contraption system gets affected by another team’s contraption system due to mistake ?

Ans. Points (according to the extent of damage on the other team’s contraption system) will be deducted from the team’s total score which caused the damage. Extra time will be given to the team which had their contraption system damaged, to fix it.

 Q5. Are there any time restrictions for setting up the contraption system and executing the task?

Ans. There are no time restrictions for setting up the contraption system. The number of steps, complexity of system and time taken will be the factors in the execution of the given task. However, there will be a time limit for the completion of the task.

Q6.What is a step?

Ans. A step is defined as an action that results in another action which works toward the final aim of the system.

 Q7.What is a parallel step?

Ans. A parallel step is defined as the action that initiates two or more steps at the same time but both the initiated steps must have some contribution towards the final aim of the system.

 Q8. What is a gradient?

Ans. An inclined surface.

 Q9.Will balls be provided to hit the cup arrangement?

Ans.No

 Q10. How many chances will be given to a team to complete the given task?

Ans. It’s not fixed. It can be any number but the team has to complete the task within the specified time limit. However more number of chances would result in more points being deducted. The team has to stop their system if the time limit is crossed.

RULES:-

  • Human interference is not allowed. Participants are allowed to make a maximum of  2 checkpoints, in case the task fails, participants can start from the nearest checkpoint.

  • Judges’ decision shall be final and binding to all.

  • Two team members may interact with the contraption system once the evaluation has begun. This includes resetting the machine.

  • The number of members in a team is restricted to five (5). Students from different educational institutes can form a team.

  • The size of the object should not exceed 80 mm.

  • The arrangement should fit into an area (2m x 2m).

  • Participants are asked to make a minimum of 2 loops in the contraption.

  • No hazardous materials or explosives can be used on the machine.  

  • Participants should use at least two different gradients.

  • Teams will be given two chances to hit the pillar arrangement .

  • The height of the contraption system should lie in the range of 1.5-2 metres.

  • The pillars should be made to fall only by direct physical contact .

  • No points are awarded if the hitting is done by any direct energy .

  • The Pillar Arrangement is fixed. No changes are made in the placement of the pillars.
