Working Light Serpentine Hose Connection Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing working lights face issues with fixed illumination angles, poor connection tightness leading to water and dust ingress, and ease of damage, as well as user errors during assembly, especially in low-light conditions.
Innovation Solution
A serpentine hose with a deformable outer corrugated pipe and star-shaped support structure, along with internal flexible metal wire, provides secure and adjustable connections between the base and illumination member using internal threads, preventing direct mounting errors and enhancing durability, while a pivotable lamp cap allows multi-angle illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a serpentine hose with buckle and slot connection is used to connect base and illumination member, then the working light can be flexibly positioned, but the connection tightness is poor allowing water or dust to enter
Solution Approach 1:
The patent employs a flexible serpentine hose as the connection structure between base and illumination member. The hose can be bent and positioned flexibly while maintaining a sealed connection that prevents water and dust ingress, resolving the contradiction between flexibility and connection tightness.
2Reliability
If the serpentine hose is fixed by hanging on an object, then the working light can be secured, but the illumination angle becomes fixed and difficult to adjust
Solution Approach 1:
The patent makes the illumination member pivotable relative to the serpentine hose connection, allowing dynamic adjustment of the illumination angle while the hose remains securely fixed. This enables both secure fixation and flexible angle adjustment to coexist.
3Ease of manufacture
If the base and illumination member have different connection structures, then they can be connected directly, but users may make mounting errors especially in low-light conditions
Solution Approach 1:
The patent employs asymmetric connection structures on the base and illumination member that are designed to mate in only one correct orientation. This asymmetric design prevents mounting errors by making incorrect assembly physically impossible, while still allowing direct connection capability.
4Ease of manufacture
If the buckle connection is used to attach serpentine hose, then assembly is simple, but the buckle may easily be damaged influencing lifetime
Solution Approach 1:
The patent replaces the buckle connection with a flexible hose insertion connection where the hose is inserted into sealed slots. This eliminates the buckle component that is prone to damage, while maintaining assembly simplicity through the push-in design.

AI summary
The present invention discloses a working light, comprising a base, an illumination member and a switch control, a battery is arranged inside said base to supply power to said illumination member, said base is connected to said illumination member by a connection portion, said base and said illumination member are respectively connected to said connection portion by the same connection structures. By this arrangement, said base cannot be connected to said illumination member directly, users would not make mounting errors in use. In a preferred embodiment of the present invention, said connection portion is a serpentine hose or a joint-sleeve, wherein the serpentine hose includes a corrugated pipe and an internal star-shaped pipe, a wire and an iron wire which are arranged inside the corrugated pipe, this serpentine hose couples stiffness with toughness, after adjusting the curved shape, it is not easily deformed. The working light in the present invention overcomes several problems of the current portable illumination light and have a wide range of application, which can satisfy different requirements of users.
