Solution Overview
Problem
Existing portable LED light sources are not suitable for use in water environments due to lack of waterproofing, limiting their application and usability.
Innovation Solution
A waterproof portable LED lamp design featuring a housing with a light source, power supply, and switch within a silicone and ABS plastic structure, a flexible transparent cover for activation, and a reflector for directed light output, ensuring watertight sealing and buoyancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional portable LED light source is used, then it is compact and easy to use, but it cannot be used in water environments
Solution Approach 1:
The lamp is divided into separate waterproof chambers - a first waterproof chamber containing the light source and switch, and a second waterproof chamber containing the power supply. These chambers are isolated from each other except for electrical connections, allowing independent protection and sealing of each component against water
Solution Approach 2:
A flexible transparent cover made of elastomeric material is used to seal the opening in the housing. This flexible membrane maintains waterproof integrity while allowing light transmission and user interaction through the cover for switch activation
2Adaptability or versatility
If the lamp is made waterproof with sealed housing, then it can be used underwater, but the switch operation becomes difficult
Solution Approach 1:
The flexible transparent cover acts as an intermediary between the user and the switch. Users can activate the switch by pressing through the cover from the outside, eliminating the need for direct contact with internal components and maintaining waterproof sealing while preserving ease of operation
Solution Approach 2:
The transparent cover allows visual feedback about the lamp's operational state. The cover can indicate whether the lamp is on or off through light transmission, providing intuitive status information to users without compromising waterproof integrity
3Illumination intensity
If a flexible transparent cover is used for the opening, then light can egress and the cover is watertight, but the cover needs to be sealed securely
Solution Approach 1:
The housing combines rigid plastic material for structural strength with an elastomeric flexible cover for sealing and light transmission. This composite construction integrates the complementary properties of rigid and flexible materials to achieve both structural integrity and waterproof flexibility
Solution Approach 2:
The elastomeric flexible cover serves as a sealing membrane that conformally seals around the opening while maintaining light transmission. The flexibility of this thin film allows it to accommodate slight dimensional variations and maintain reliable waterproof contact

AI summary
A waterproof portable lamp (10) comprises a housing (12); a light source (14) including a plurality of LEDs, a power supply (16) for said light source (14) and a switch (18) for energizing said light source (14) contained within said housing (12). An opening (20) is formed in said housing (12) permitting egress of light when said light source (14) is energized. A flexible, transparent cover (22) is peripherally sealed to said opening (20) in a watertight manner and a switch activator (24) is substantially centrally located on and fixed to said flexible, transparent cover (22). The lamp (10) is activated be depressing the center of the flexible cover (22), which moves the switch activator (24) into contact with the switch (18).
