Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inflating tools face issues such as high operating resistance due to integrated bushing movement, inconvenient assembly, and lack of limiting members, leading to potential damage and inefficiency.
Innovation Solution
A bi-directional inflating tool with a handle assembly, adapter assembly, nozzle connectors, moving control sleeves, detent assemblies, and valve assemblies, allowing for simplified and effort-saving operation by axial displacement of control sleeves and detent members, with features like included angles and circlips for secure engagement and disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If two ends of the bushing are integrated and movable at the same time, then the structure is simplified, but the operating resistance becomes larger and operation becomes inconvenient
Solution Approach 1:
The bushing is divided into a first bushing and a second bushing that can move independently. This segmentation allows each bushing to be operated separately, reducing the operating resistance and improving ease of operation while maintaining structural simplicity through the integrated design of the two bushings working together.
2Device complexity
If the adapter tube is directly integrated with the handle rod, then the assembly structure is simplified, but the assembly process becomes inconvenient
Solution Approach 1:
The adapter tube is separated from the handle rod into distinct components. The adapter tube can be independently assembled with the nozzle connector, while the handle rod remains a separate operational component. This segmentation simplifies the assembly process and manufacturing while maintaining a compact integrated structure during operation.
3Device complexity
If the detent is directly pushed by the bushing, then the structure is simplified, but the bushing becomes liable to be damaged
Solution Approach 1:
A limiting member is introduced as an intermediary component between the bushing and the detent. This limiting member receives the pushing force from the bushing and transmits it to the detent, protecting the bushing from direct contact and potential damage while maintaining the simplified structural design.
4Device complexity
If there is no limiting member between the bushing and the inflating fitting, then the structure is simplified, but the bushing can axially move too much and become liable to be damaged by collision
Solution Approach 1:
A limiting member is positioned between the bushing and the inflating fitting to serve as a protective intermediary. This component restricts the axial movement of the bushing, preventing excessive displacement and potential collision damage, while maintaining a relatively simple overall structure through its integrated design.

AI summary
A bi-directional inflating tool includes a handle assembly having an inner tube, an outer tube movably sleeved onto the inner tube and a sleeve pushing and pulling member with a sleeve pushing portion and a sleeve pulling portion, an adapter assembly connected to the inner tube, two nozzle connectors connected to the adapter assembly, two moving control sleeves sleeved onto the nozzle connectors respectively and each having an abutted moving portion, which are respectively pushed by the sleeve pushing portion and pulled by the sleeve pulling portion to displace axially, two detent assemblies controlled by the moving control sleeves respectively for engagement with the gas nozzle, and two valve assemblies controlling the communication of the adapter assembly with the nozzle connectors respectively for aeration. The moving control sleeves are operated separately, bringing simpleness and effort-saving, solving the time-consuming and laborious problem of the conventional bi-directional inflating tool.
