Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transcranial light regulation and near-infrared spectroscopy devices are hindered by hair blocking, leading to reduced light propagation and inaccurate measurements due to hair obstructing the light path.
Innovation Solution
A head optical application device with deployable components that gather or deploy under environmental forces, such as temperature or manual manipulation, to push hair aside, allowing light to directly reach the scalp without electrical driving mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional transcranial light regulation products are used, then the device structure is simple, but hair blocking reduces light propagation rate and affects treatment effectiveness
Solution Approach 1:
The deployable components are designed to dynamically change from a gathered state during insertion to a deployed state during operation. This dynamic transformation allows the device to adapt its structure: compact during insertion for simplicity, and expanded during use to push hair aside and improve light propagation rate without requiring complex electrical driving mechanisms.
2Productivity
If deployable components are added to push hair aside, then light propagation rate improves, but device complexity increases
Solution Approach 1:
The deployable components utilize elastic restoration force inherent in their material structure to automatically deploy and push hair aside once inserted. The components self-activate without requiring external electrical driving devices, control systems, or power sources. This self-service mechanism improves light propagation rate while avoiding the complexity of electrical actuation systems.
Solution Approach 2:
The invention replaces potential electrical driving mechanisms with a passive mechanical elastic restoration system. The deployable components rely on elastic force stored in their structure to perform the hair-parting function, substituting complex electrical-mechanical conversion systems with a simpler pure mechanical elastic restoration mechanism.
3Measurement precision
If near-infrared spectroscopy equipment is used, then cerebral function measurement is possible, but hair blocking makes it difficult to obtain accurate measurement results
Solution Approach 1:
The deployable components perform preliminary action by pushing hair aside before the near-infrared light needs to propagate to the scalp. This pre-clearing of the optical path ensures that when the measurement is taken, the light can directly reach the scalp without hair interference, thereby improving measurement accuracy of cerebral blood oxygen signals.

AI summary
The present disclosure provides a head optical application device, a transcranial light regulation apparatus and a near-infrared apparatus. The head optical application device comprises a support component, an optical component, and deployable components. The support component is constructed to mount an optical component. The optical component is constructed to transmit light to or receive light from scalp. The deployable components are provided on the support component, and are constructed to deploy or gather the distal ends under the action of force caused by the surrounding environment. Without the need for providing an electrical driving apparatus, the distal ends of the deployable components can be inserted into the user's hair gap in a gathered state, and distal ends of the deployable components can part (push) the hair blocking light (aside) in a deployed state after insertion, improving the problem of low light propagation rate due to hair blocking.
