Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing puncture repair kits face issues with hose misalignment, instability of the bottle unit, risk of compressor device fall and electrical failure due to rainwater accumulation during use.
Innovation Solution
Direct connection between the compressor device and bottle unit, with the power switch and pressure gauge mounted on the storage case's bottom surface and drainage channels to prevent rainwater accumulation, eliminating the need for an air intake hose and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct connection between compressor device and bottle unit is implemented, then hose misalignment is eliminated and stability is improved, but the compressor device becomes vulnerable to damage from falling and rainwater accumulation
Solution Approach 1:
The patent applies beforehand cushioning by providing a case that surrounds and protects the compressor device. The case includes cushioning structures that absorb impact forces if the compressor device falls, and drainage structures that prevent rainwater accumulation on the upper surface. This protective case is implemented in advance to mitigate potential damage from falling and rainwater exposure.
2Ease of operation
If power switch and pressure gauge are mounted on the upper surface for easy operation, then ease of operation is improved, but the components become vulnerable to breakage from falling
Solution Approach 1:
The power switch and pressure gauge are mounted on the upper surface of the case with beforehand cushioning structures beneath them. These cushioning structures absorb impact forces during falling, protecting the mounted components from breakage while maintaining their accessibility for operation.
3Volume of moving object
If the compressor device is made compact for portability, then ease of transport is improved, but the position of gravity center rises causing instability
Solution Approach 1:
The patent resolves the stability issue by changing the spatial arrangement in the vertical dimension. The bottle unit is positioned below the compressor device, extending downward to lower the overall gravity center. This dimensional adjustment maintains portability while achieving stable operation during use.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides increased stability, prevents incorrect hose laying, protects the power switch and pressure gauge from damage, and prevents electrical failures due to rainwater, ensuring reliable operation.
Implementation Method 1
drainage channels are formed upon the upper surface so as to extend at a downward incline from the mounting depressions toward outer side surfaces of the storage case

AI summary
Disclosed is a puncture repair kit comprising a compressor device (2), further comprising a power switch (SW), a compressor main body (13), and a pressure gauge (22), stored within a storage case (9); and a bottle unit (3), wherein a cap (6) is attached upon an opening portion (5) of a bottle container (4) containing a puncture sealant. One of a set of a compressed air discharge opening (8) of the compressor device (2) and an air intake opening (27) of the cap (6) comprises a connection nozzle (41), and the other of the set comprises a nozzle receiver (28) wherein the connection nozzle (41) is inserted and fitted. The upper surface (SU) of the storage case (9) comprises a mounting depression (54) for mounting the power switch and a mounting depression (55) for mounting the pressure gauge. The power switch (SW) and the pressure gauge (22) are mounted upon the bottom portions (54a, 55a) of the respective mounting depressions (54, 55) at distances (H1, H2) of 3-15mm downward from the upper surface (SU). Drainage channels (57, 60) that extend at a downward incline from the mount depressions (54, 55) toward the outer side surfaces of the storage case (9) are formed upon the upper surface (SU).
