Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing contact sensors cannot change the mode of diffused light on their outer surface in response to deformation caused by external forces, limiting their ability to dynamically adjust their visual output based on deformation states.
Innovation Solution
A light emitting apparatus comprising a visible light emitter, an invisible light emitter, an invisible light receiver, and a controller, where the cover member deforms with external force, reflecting invisible light and diffusing visible light, allowing the controller to adjust the emission mode of visible light based on the deformation state detected by the invisible light receiver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a contact sensor uses a cover member that deforms under external force, then the sensor can detect contact force through light reception, but the sensor cannot dynamically change the mode of diffused light on its outer surface in response to deformation
Solution Approach 1:
The patent applies the dynamics principle by making the cover member deformable under external force, allowing it to change shape dynamically. This deformation is detected by the invisible light receiver, which then triggers the controller to dynamically adjust the visible light emitter's operation mode, creating a dynamic response system that adapts to external interactions.
Solution Approach 2:
The patent implements feedback by using the invisible light receiver to detect the deformation state of the cover member and feeding this information back to the controller. The controller then adjusts the visible light emitter based on this feedback, creating a closed-loop system where the output (light emission mode) is controlled by the detected input (deformation state).
2Illumination intensity
If the cover member is made transparent to visible light, then diffused light can be seen on the outer surface, but the invisible light receiver cannot accurately detect deformation
Solution Approach 1:
The patent uses an intermediary approach by introducing invisible light (infrared or ultraviolet) as a separate detection channel that does not interfere with the visible light transmission function. The cover member is designed to be transparent to visible light while simultaneously being reflective to invisible light, allowing both functions to coexist without compromising either visibility or detection accuracy.
Solution Approach 2:
The patent applies local quality by giving different optical properties to the cover member for different wavelengths of light. The cover member is designed to be transparent to visible light wavelengths while being reflective to invisible light wavelengths, allowing each wavelength range to interact with the cover member in a manner optimized for its specific function.

AI summary
A light emitting apparatus has a visible light emitter, an invisible light emitter, invisible light receiver for receiving invisible light emitted from the invisible light emitter, cover member covering these components, and controller for controlling operation of the visible light emitter. The cover member has flexibility so as to deform when receiving external force, and at least partially reflects invisible light and passes and diffuses visible light. The invisible light emitter emits invisible light toward an inside surface of the cover member, and the invisible light receiver receives invisible light and reflected by the cover member. The controller controls an emission mode of visible light emitted from the visible light emitter in accordance with a reception state of invisible light at the invisible light receiver, which changes in accordance with deformation of the cover member.
