Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional kayak paddles lack visibility in low-light conditions, making it difficult for users to navigate and be seen while paddling, especially in early morning or late evening hours.
Innovation Solution
A kayak paddle with translucent blades and integrated light sources, powered by a battery, which emits light from within the blades to enhance visibility and safety, featuring light-emitting diodes (LEDs) that can produce various colors and a distress pattern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional kayak paddles are used, then the structure is simple and cost-effective, but the visibility in low-light conditions is poor
Solution Approach 1:
The patent combines the paddle blade and light housing into a single integrated structure. The blade serves dual purposes: as the propelling surface and as the housing for the light source and translucent cover, eliminating the need for separate light mounting structures and reducing overall complexity.
Solution Approach 2:
The patent applies translucency locally to specific portions of the blade rather than making the entire paddle complex. The translucent portion is strategically positioned at the leading edge or tip of the blade where light emission provides maximum visibility, while the rest of the paddle maintains traditional simple construction.
2Illumination intensity
If light sources are integrated into the paddle, then visibility is improved, but the weight of the paddle increases
Solution Approach 1:
The patent employs battery-powered LED light sources that are lightweight and energy-efficient. The batteries are designed to be replaceable, allowing users to swap them when depleted rather than carrying heavy rechargeable systems or permanent power sources, thus minimizing added weight.
Solution Approach 2:
The patent uses multiple LEDs capable of emitting different colors (red, green, yellow, white) to provide visibility without requiring high intensity in a single color. This allows the use of lower-power LEDs that consume less energy and add minimal weight, while still achieving effective visibility through color variety.
3Illumination intensity
If multiple light sources are used, then visibility and safety are enhanced, but the energy consumption increases
Solution Approach 1:
The patent incorporates control circuitry that enables periodic or intermittent operation of the light sources. The LEDs can be programmed to flash, blink, or operate in alternating patterns rather than continuous illumination, significantly reducing energy consumption while maintaining effective visibility and safety signaling.
Solution Approach 2:
The patent designs the light system to serve multiple functions simultaneously: illumination for the paddler's visibility, signaling to others on the water, and potential distress signaling through specific color patterns. This multi-functionality justifies the energy consumption of multiple LEDs by providing diverse operational modes from a single power source.
4Illumination intensity
If translucent material is used for blades, then light emission is improved, but the structural strength may be reduced
Solution Approach 1:
The patent employs composite construction for the paddle blade, combining translucent materials (such as translucent plastic or fiberglass) with reinforcing elements. The blade may feature a translucent outer shell with internal structural supports or a translucent resin infused into a fibrous reinforcement matrix, achieving both light transmission and mechanical strength.
Solution Approach 2:
The patent applies translucent material selectively to specific regions of the blade where light emission is most beneficial, such as the leading edge, tip, or trailing edge portions. The high-stress areas of the blade maintain traditional opaque, high-strength construction, while only the portions requiring light transmission use translucent material, thus preserving overall structural integrity.

Function Achieved in This Case
The illuminated kayak paddle improves visibility and safety by providing light for the user and making the paddle more visible to others, enhancing navigation and awareness in low-light conditions.

AI summary
A kayak paddle includes a tubular shaft having a first distal end and a second distal end, a first blade connected to the first distal end of the tubular shaft, and a second blade connected to the second distal end of the tubular shaft, wherein the first and second blades are made with a translucent material. The kayak paddle further includes a first light source secured within the tubular shaft and oriented to emit light from the first distal end into the first blade, a second light source secured within the tubular shaft and oriented to emit light from the second distal end into the second blade, and a battery electrically connected to the first and second light sources to supply electrical current that causes the first and second light sources to emit light.
