I interpreted it as brainstorming ways to actively sabotage success. "Solutions" that appears superficially plausible, but undermine the outcome in real world situations.

So for the dust filter, maybe selecting a material that's only rated for high temperatures in short bursts. Or one that needs frequent, labor-intensive replacements in that dangerous environment. Or test that your filter survives at high temperatures, and test the filtration efficacy, but forget to test the efficacy at high temperatures.
