Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a uniform thickness insulating layer is applied to protect sensor units and wiring, then mechanical protection and electrical insulation are improved, but detection accuracy and energy irradiation efficiency deteriorate due to excessive insulation coverage
Solution Approach 1:
The patent applies different thicknesses of insulating layers to different regions of the oral appliance. The first insulating layer has a first thickness in a first region, while the second insulating layer has a second thickness in a second region. This local differentiation allows the appliance to have sufficient insulation and protection in certain areas while maintaining sensor sensitivity and energy irradiation efficiency in other areas where thinner insulation is applied.
2Reliability
If insulating layers are applied to protect sensor units, then electrical insulation is improved, but sensitivity and detection accuracy worsen due to reduced sensor exposure
Solution Approach 1:
The patent implements local quality by applying insulating layers with different thicknesses to different regions. In regions where sensor units are located, the insulating layer thickness is controlled to maintain detection accuracy, while in other regions providing structural support or wiring protection, thicker insulating layers are applied for enhanced electrical insulation and mechanical protection.
3Reliability
If energy irradiation units are covered with insulating layers, then mechanical protection is improved, but energy irradiation efficiency deteriorates due to blocked energy transmission
Solution Approach 1:
The patent applies local quality principles by differentiating insulating layer thickness across different functional regions. In regions containing energy irradiation units, the insulating layer is applied with appropriate thickness to allow effective energy transmission while providing necessary mechanical protection. In other regions requiring higher structural protection, thicker insulating layers are used.

AI summary
A sheet-shaped oral appliance is provided that is detachably attached to an oral body device and includes a functional portion with a sensor unit that acquires information in an oral cavity and an energy irradiation unit that radiates energy into the oral cavity, an electrical connection portion, and a wiring portion that connects at least one of the sensor unit and the energy irradiation unit to the electrical connection portion. The functional portion, the connection portion, and the wiring portion are formed by a wiring layer having first and second main surfaces that oppose each other, a first insulating layer arranged on the first main surface and a second insulating layer arranged on the second main surface. Moreover, in the functional portion, a thickness of the first insulating layer is smaller than a thickness of the second insulating layer.
