Water Bottle Rejection System | Planning Guide
Why should detection-to-reject travel time be reviewed after a speed change?
"These are invented teaching inputs, not equipment ratings, market prices or an accepted tolerance. The two scenarios change one assumption while holding the other inputs constant. Use the comparison to identify what must be measured or agreed for your project."
Two planning scenarios
Record item,Unit,Scenario A,Scenario B,How to establish this input
Detection-to-reject distance,m,1.8,1.8,"Use the applicable drawing revision or an actual dimension record, with the stated unit. Identify internal, external, usable or clearance dimensions explicitly. A nominal catalogue dimension does not establish the installed usable space."
Conveyor speed,m/s,0.6,0.9,"Record the quantity or distance and the corresponding observation time, named product format and operating mode. Distinguish a measured rate from a quoted capability; an average across a different window is not the same input."
Calculated comparison
Record item,Unit,Scenario A,Scenario B
Time,s,3,2
What the comparison means,"Detection distance stays fixed while conveyor speed rises, shortening nominal travel time. The result is not a delay value to enter directly into production controls. Tracking logic, acceleration and actuator behaviour are outside this simple division. Demonstrate that the identified rejected bottle reaches the intended secured destination."
Evidence to request,"Ask for detection and rejection locations, speed signal definition, tracking method, actuator response evidence and a documented reject-confirmation challenge test."
Input assumptions,"Identify the bottle, pack or material configuration, operating mode and measurement boundary. State the start and finish of the observation and which accepted output the comparison represents; unlike boundaries cannot establish a performance improvement."
How to establish this input,"Mark every input as measured, taken from a drawing, quoted or assumed. Retain the source document identifier, revision, date and responsible person. The same numeral with a different unit or data status is not automatically a comparable input."
Project decision record,Ask the responsible supplier and buyer to agree actual acceptance criteria and the evidence that will demonstrate them. Teaching values and calculated outputs on this page do not become approved operating settings or contractual performance guarantees.
Evidence to request,"Record the decision affected by the result, the measurement or trial still needed, its owner and the next review. Keep unresolved items visible in the handover file instead of changing the figures to make a preferred equipment option appear acceptable."
