Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sensor elements are difficult to manufacture and remove efficiently, as they require complex processes and often result in leftover film portions that can obstruct the removal of film-shaped sensors.
Innovation Solution
A sensor element design featuring a tape-shaped mount film with film-shaped sensors spaced at intervals, allowing for easier removal by half-cutting and bending, utilizing a bonding layer and incorporating recessed or protruded portions for simplified extraction, and a sensor cartridge configuration that facilitates the unwinding and removal of sensors with a rotary mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple film-shaped sensors are bonded closely together on the mount film to maximize sensor density, then the quantity of sensors per unit area increases, but the removal of individual sensors becomes difficult due to lack of spacing
Solution Approach 1:
The patent divides the mount film into segmented regions with spacing between sensors. The crosswise length of each sensor is intentionally made shorter than the mount film width, creating gaps that segment the sensor array. This segmentation allows individual sensors to be removed independently without affecting adjacent sensors, resolving the contradiction between high density and easy removal.
2Loss of substance
If the crosswise length of each sensor equals the full width of the mount film to maximize material utilization, then material waste is reduced, but the manufacturing process becomes more complex due to the need to remove leftover film portions
Solution Approach 1:
The patent extracts only the necessary sensor portions from the mount film by making the sensor crosswise length shorter than the film width. This extraction approach leaves manageable leftover film portions that can remain on the mount film without requiring complex removal processes, thus simplifying manufacturing while minimizing material waste.
3Area of stationary object
If sensors are bonded without spacing to maximize space utilization, then the area coverage is improved, but the exfoliation and removal of sensors from the mount film becomes difficult
Solution Approach 1:
The patent applies local quality by creating different regions on the mount film: sensor-bonded regions with optimal spacing and leftover film regions. The spacing between sensors creates local gaps that facilitate exfoliation while maintaining high area coverage. This local differentiation resolves the contradiction between maximum coverage and easy exfoliation.
