Automated Cable Specimen Preparation System for IS 10810 and IS 7098 Compliance.
Ministry of Consumer Affairs, Food & Public Distribution · Smart Automation · Hardware
A rare statement where a judge can verify your result with a caliper and the field is nearly empty, but the standard leaves you no room to innovate and the whole submission lives or dies on whether your mechanics actually hold tolerance.
What it actually is
Testing whether an electrical cable meets Indian standards starts with preparing samples by hand — cutting, straightening, slicing and punching them into dumbbell shapes — and every one of those manual steps introduces variation that corrupts the test result. The ask is a machine that prepares those samples automatically to the exact dimensions the standards require. It has to handle different cable types and thicknesses without being reset each time.
What to build
An automated specimen preparation machine with the modules the statement specifies: a motor-driven roller feed with adjustable clamps that straightens and holds the cable securely, an in-line diameter sensor that measures the cable and auto-adjusts cutting depth, a cutting and stripping module with programmable-depth precision blades performing clean circumferential cuts and linear stripping to the specimen lengths the relevant IS 10810 parts require, a dumbbell forming stage, automated specimen ejection with waste separation, and a PLC and HMI control layer where the operator selects the test method and the machine sets its own parameters, with closed-loop feedback on cut depth and enclosed guarding with interlocks.
Smallest thing that wins the room
Feed a length of PVC cable in, select a test method on the HMI, and have the machine strip and produce a specimen the judges can measure with a vernier caliper against the dimension the standard requires.
How crowded this one gets
A guess, projected from the 2025 statements — the last year where both the submission counts and the winners were published.
Quieter than 92% of the 226 · #18 of 226 by expected field
Few teams are likely to go here. The best odds on the board come from statements like this.
Why: central ministry statements sat below the average; hardware halves the field a software statement gets.
This is a guess, not a fact
Nobody has published 2026’s numbers yet. This is an analysed estimate from last year’s pattern, so please do not take it as the truth — check the live counter on the SIH portal before you decide anything. The range covers the middle half of likely outcomes, so one statement in two lands outside it. Entry closes at 500 ideas per statement, so no range goes past that — a statement that reaches the cap fills and shuts rather than drawing an unlimited crowd. The model reads only three things a team can see before choosing — software or hardware, the theme, and what kind of body posted it — and those explain about a quarter of the variation in last year’s field sizes (R² 0.25 on held-out statements). Trust the band more than the number, and the ordering more than either. It cannot see how good your idea is, which is the part that actually decides it.
The scores
The number is the shorthand. The line under it is the reason.
Acceptance potential
3/5A physical machine with a claim a judge can measure in the room and a field almost nobody will enter are real advantages, but the standard prescribes the entire output and the description prescribes the mechanism, so there is very little for a panel to reward beyond precise execution.
Feasibility
3/5A demonstrator with stepper-driven rollers, clamps, a blade carriage and an optical diameter sensor is genuinely buildable for tens of thousands of rupees, but hitting the dimensional tolerances that IS 10810 actually demands for insulation thickness and dumbbell specimens with student-fabricated mechanics is much harder than making the mechanism move, and the standards themselves sit behind BIS paywalls.
Innovation scope
2/5The machine architecture is dictated module by module — roller feed, adjustable clamps, programmable-depth blades, diameter sensor, PLC and HMI, automated ejection — and the output geometry is fixed by the Indian Standards, so almost every design decision has already been made for you.
Clarity
5/5Every module is named with its function, the standards and their relevant parts are cited, the existing manual process is described step by step, and the safety requirements are stated, so there is essentially nothing to interpret.
Effort
HeavyA precision mechanical build with a feed mechanism, a blade carriage with programmable depth, a sensing loop, ejection and waste handling, plus PLC control and an HMI, is a full mechatronics project where fabrication tolerance rather than code will set your schedule.
Demo-ability
EasyAlmost uniquely on this portal, a judge can verify your claim on the spot — put a caliper on the specimen your machine just made and check it against the dimension the standard requires, which is far stronger than any dashboard.
In its favour
- Green flag: The judge can measure your output with a caliper against a published standard dimension, which turns your claim into a verifiable fact rather than an assertion — very few statements allow this
- Green flag: The published standards remove requirement ambiguity entirely, so no time is lost deciding what correct means
- Green flag: Test lab automation attracts almost no hackathon entries, so a working machine has very little to compete against
- Green flag: The build is genuinely affordable — steppers, an aluminium extrusion frame, blades and an optical sensor are all cheap and available off the shelf
Against it
- Red flag: IS 10810 and IS 7098 are paid BIS documents, so obtaining the exact dimensional tolerances you are being asked to meet has a cost and access barrier — sort this out before you start
- Red flag: Innovation scope is close to zero because the standard fixes the output and the description fixes the mechanism, so a panel looking for novelty will find execution quality and nothing else
- Red flag: Cutting depth precision on PVC and XLPE without deforming the insulation is genuinely difficult, and a 3D-printed blade carriage will flex enough to miss the tolerance the whole machine exists to hit
- Red flag: The machine must handle multiple cable types and diameters automatically, so demonstrating on one cable size answers a much easier problem than the one stated
