Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional adhesive layer is used to bond the glass sheet and optical component, then the bonding function is achieved, but abnormal refraction and reflection of light occur
Solution Approach 1:
The adhesive layer is designed with non-uniform thickness, featuring a first thickness in a first region and a second thickness in a second region. This local variation in thickness creates different optical path lengths in different regions, allowing the adhesive layer to maintain bonding functionality while reducing abnormal refraction and reflection effects through controlled optical path management.
Solution Approach 2:
The invention changes the physical parameter of the adhesive layer by controlling its thickness distribution. By adjusting the thickness from a first value in the first region to a second value in the second region, the optical properties of the adhesive layer are modified, thereby mitigating the harmful refraction and reflection effects while preserving the bonding function.
2Strength
If the adhesive layer thickness is increased to improve bonding strength, then bonding strength is enhanced, but light aberrations are worsened
Solution Approach 1:
The adhesive layer implements different thickness values in different regions: a first thickness in the first region and a second thickness in the second region. This local differentiation allows the adhesive layer to provide sufficient bonding strength in critical areas while minimizing light path length in regions where thickness would cause aberrations, thus resolving the contradiction between bonding strength and light quality.
Solution Approach 2:
The adhesive layer is effectively segmented into different thickness zones (first region and second region), each optimized for different functions. This segmentation allows the bonding function to be optimized in one region while the optical performance is optimized in another region, resolving the conflict between mechanical and optical requirements.

AI summary
An optical device includes an electronic component, a light-permeable layer, and a ring-shaped support that is sandwiched between the electronic component and the light-permeable layer. A top surface of the electronic component includes an optical region and a carrying region that surrounds the optical region. The ring-shaped support includes an adhesive layer and an additive module that is incompletely soluble in the adhesive layer. The adhesive layer is ring-shaped and is disposed on the carrying region of the electronic component. The additive module includes a plurality of inner additives and a plurality of shape-formation additives, which are entirely embedded in the adhesive layer. The inner additives are arranged away from inner side and outer side of the adhesive layer. The shape-formation additives are arranged adjacent to the inner side, so as to enable the inner side to form a plurality of protruding microstructures.
