Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing optical substrates to base substrates fail to effectively transfer motion while isolating the optical substrate from thermal distortions caused by steering mechanisms, leading to performance degradation due to excessive adhesive use and thermal transfer.
Innovation Solution
A steerable configuration-enhancing optical assembly that uses a selective adhesive complex with multiple small, discrete adhesive units positioned strategically on the optical substrate, employing adhesives with varying contraction coefficients to minimize thermal impact and correct deviations from the design configuration, and retainment features on the base substrate to control adhesive placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive is used to secure optical substrate to base substrate, then bonding strength is improved, but thermal transfer increases causing optical distortion
Solution Approach 1:
The adhesive complex is divided into multiple discrete adhesive units distributed across the base substrate. Each unit provides localized bonding while minimizing overall thermal transfer to the optical substrate, resolving the contradiction between achieving sufficient bonding strength and reducing thermal distortion.
2Ease of operation
If steering mechanism is used to orient base substrate, then optical assembly steering is improved, but thermal distortion of optical substrate increases
Solution Approach 1:
The segmented adhesive complex acts as thermal isolation between the steering mechanism (attached to base substrate) and the optical substrate. This allows the base substrate to be steered freely while the optical substrate remains thermally isolated, maintaining both steering capability and reducing thermal distortion.
3Force
If adhesive complex is used to secure optical substrate, then motion transfer is improved, but adhesive usage and complexity increase
Solution Approach 1:
The adhesive complex consists of multiple simple discrete adhesive units rather than a single complex adhesive structure. Each unit is straightforward in design but collectively they provide effective motion transfer from base substrate to optical substrate while maintaining simplicity in manufacturing.
