Scalp Care Cap Ventilation for Laser Heat Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laser hair loss treatment devices are designed only for laser light irradiation, leading to scalp heat buildup, lack user convenience, and do not prioritize user safety.
Innovation Solution
A cap device that combines laser light therapy with air ventilation to cool the scalp, adjustable sizing for user comfort, and safety features like wearing detection to prevent operation when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If laser light is irradiated to the scalp for hair loss treatment, then hair growth is promoted and hair loss is delayed, but heat is applied to the scalp which may become another cause of hair loss
Solution Approach 1:
The patent incorporates a cooling fan and air circulation system that actively removes heat from the scalp during laser treatment. The housing includes air inlet holes and air outlet holes with fans to create airflow that cools the scalp, converting the harmful heat effect into a beneficial cooling effect that prevents heat-induced hair loss while maintaining the therapeutic laser irradiation
2Ease of operation
If the cap device is designed to fit various head sizes for user convenience, then user comfort is improved, but device complexity increases
Solution Approach 1:
The patent employs an adjustable band structure with buckles that allows the cap device to be dynamically adjusted to fit different head circumferences. The band includes multiple adjustment positions and detachable buckles, enabling users to customize the fit for comfort while maintaining a relatively simple overall device structure
3Productivity
If the cap device operates continuously to maximize treatment effectiveness, then productivity is improved, but user safety is compromised when not worn
Solution Approach 1:
The patent incorporates a sensor that detects whether the cap device is properly worn on the user's head. The control unit receives feedback from this sensor and automatically controls the laser irradiation and fan operation accordingly - only activating these functions when the sensor confirms proper wearing, thereby ensuring safety while maintaining treatment effectiveness when in use
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents hair loss, promotes hair growth, ensures user convenience through adjustable fit, and enhances safety by preventing operation when not worn.
Implementation Method 1
The substrate has a plurality of laser diodes and a plurality of infrared ray and red light emitting diodes, which irradiate light to the scalp
Implementation Method 2
a laser hair loss treatment device, which is configured to irradiate laser light based on the low-level laser therapy to a scalp
Implementation Method 3
The exterior cover is configured to define an air flow passage along an outer surface of the interior cover, and has a vent hole for sucking air from an outside. The blower is configured to suck air through the vent hole and to emit the air to the scalp through the plurality of emitting holes via the air flow passage

AI summary
A cap device for scalp care is provided. The cap device includes an interior cover, an exterior cover coupled to the interior cover, a substrate, and a blower. The interior cover covers the scalp, and has emitting holes for emitting air. The exterior cover defines an air flow passage along the interior cover, and has a vent hole for sucking air. The substrate is coupled to the interior cover in the air flow passage to cover an outer surface of the interior cover. The substrate has laser diodes, infrared ray and red light emitting diodes, and through holes corresponding to the emitting holes. The blower communicates with the air flow passage at an upper end of the interior cover. The blower sucks air through the vent hole and emits the air to the scalp through the emitting holes via the air flow passage.
