Product Opportunity Analysis:

• User Need Identified: People often run into loose doorknobs, especially those secured by hidden set screws (grub screws), and they don't have the right small tools or variety of screws to fix them. This can be really frustrating, leading to multiple trips to the hardware store or resorting to less-than-ideal solutions like strong adhesives when a simple mechanical fix might work.

• Specific Product Suggestion: "Universal Doorknob Tightening & Repair Kit"

• Kit Contents:

  1. Assortment of Set Screws (Grub Screws): Various common sizes and thread pitches (e.g., M3, M4, M5, #6-32, #8-32) in different lengths. Include both hex socket and slotted types if they are commonly used.
  2. Allen Key Set (Hex Keys): A set of small Allen keys corresponding to the included hex socket set screws (e.g., 1.5mm, 2mm, 2.5mm, 3mm, and their imperial equivalents).
  3. Small Precision Screwdriver Set: Including small flathead and Phillips heads, as some older or specific knobs might use these for set screws or cover plate removal.
  4. Spudger/Thin Pry Tool: A non-marring plastic tool to help remove decorative rosettes or covers that might hide set screws without damaging the doorknob finish.
  5. Small Tube of Thread-Locking Compound (e.g., Loctite Blue): For securing set screws that tend to vibrate loose, but still allowing future disassembly.
  6. Small Tube of Strong Epoxy/Adhesive (e.g., a 2-part epoxy similar to JB Weld, or a strong cyanoacrylate for metal): For situations where threads are stripped and a mechanical fix is no longer viable, or a set screw is completely lost and can't be matched.
  7. Simple, Illustrated Instruction Card/Booklet: Showing common types of doorknobs, how to locate hidden set screws, and how to use the kit components for tightening or repair.
