Adaptive Optical Plate Peeling Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adaptive optical plates, such as mirrors and lenses, are prone to breakage or deformation when released from their support arrangements due to their thin and brittle nature, making handling and replacement challenging without causing damage.
Innovation Solution
A method involving a peeling arrangement that applies sequential lifting forces to the plate along its edge, allowing it to be slowly and carefully removed from the support surface, minimizing deformation and breakage risk by maintaining contact with the support at adjacent areas until the plate is fully detached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a high force is applied to release the adaptive optical plate from the support arrangement, then the plate can be detached, but the plate breaks or deforms due to its thin and brittle nature
Solution Approach 1:
The release force is segmented and applied sequentially at different locations along the plate rather than simultaneously across the entire plate. The peeling arrangement moves along the plate, releasing small sections one after another, which distributes the mechanical stress and prevents sudden breakage or deformation of the thin plate structure
Solution Approach 2:
The peeling arrangement performs preliminary action by gradually lifting and detaching sections of the plate before complete release. This controlled sequential detachment prepares the plate for full release by progressively reducing adhesion forces, preventing sudden stress concentration that would cause breakage
2Productivity
If the entire plate is lifted simultaneously, then release is achieved quickly, but the thin plate deforms or breaks due to excessive stress
Solution Approach 1:
The plate release process is segmented into multiple sequential steps where different sections are released one after another. The peeling arrangement moves along the plate surface, detaching small areas sequentially rather than lifting the entire plate at once, maintaining both efficiency and safety
Solution Approach 2:
The peeling arrangement introduces dynamic motion to the release process, moving progressively along the plate rather than applying static force. This dynamic sequential peeling adapts the release process to the plate's mechanical limits while maintaining productive removal speed
3Stability of the object's composition
If multiple contact points are used to support the plate, then stable support is achieved, but the total release force required increases significantly
Solution Approach 1:
The total release force problem is solved by segmenting the detachment process spatially and temporally. Instead of overcoming all adhesion forces at 12,000 contact points simultaneously, the peeling arrangement sequentially releases small sections, reducing the peak force requirement while maintaining support stability during the process

AI summary
Method of releasing an adaptive optical plate (3) from an adaptive optical arrangement (4) supporting the adaptive optical plate, wherein the plate has a small thickness as compared to its surface dimensions, and is supported by the arrangement substantially along its surface (5), wherein a first area (Pl) of the plate is moved in a direction away from the support arrangement, while a second area (P2) of the plate adjacent the first area abuts the arrangement, subsequently the second area is moved in a direction away from the arrangement, while a third area (P3) of the plate adjacent the second area abuts the arrangement, and 'in the same manner sequentially further areas are moved in a direction away from the arrangement, while respective adjacent areas abut the arrangement, wherein said areas are sequentially moved in a direction away from the arrangement in at least one travelling direction such that the plate is peeled from the arrangement in said at least one travelling direction.
