Optical Scanner Projecting Section for Wire Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical scanners face damage to wires during pressurization and joining due to uneven pressure distribution, making them unsuitable for integration with other members.
Innovation Solution
The optical scanner design includes a projecting section on the movable section to absorb pressure, with the supporting section, movable section, and shaft section formed from the same substrate, reducing wire damage by distributing pressure effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If functional elements and wires are provided on the front and rear surfaces of the optical scanner, then the optical scanner can perform its scanning function, but the wires are likely to be damaged during pressurization and joining operations
Solution Approach 1:
The patent introduces a projecting section that extends in the thickness direction (z-axis) from the substrate surface. This dimensional extension creates a spatial buffer zone that prevents pressure applied during front surface joining from directly transmitting to the wire located on the rear surface, thereby protecting the wire from pressure damage while maintaining electrical connectivity
Solution Approach 2:
The projecting section acts as an intermediary protective structure between the joining pressure applied on the front surface and the wire on the rear surface. It absorbs and distributes the mechanical stress, preventing direct transmission of damaging forces to the wire, thus serving as a stress-buffering mediator
2Adaptability or versatility
If pressurization and joining are performed on the optical scanner, then another member can be integrated with the optical scanner, but the wire may be damaged by the pressure
Solution Approach 1:
By extending the projecting section in the thickness direction, the patent creates a three-dimensional protective barrier that allows planar joining operations to proceed without compromising the wire. This dimensional approach enables integration of additional members while maintaining wire integrity through spatial separation of the joining zone from the wire location
3Device complexity
If the wire is provided close to the substrate surface, then the device structure is simplified, but the wire is more susceptible to damage during pressurization and joining
Solution Approach 1:
The patent segments the substrate structure by introducing a projecting section that creates distinct functional zones: a protected wire region and a joining region. This segmentation allows the wire to remain close to the substrate for structural simplicity while the projecting section creates a protective barrier that prevents pressure transmission to the wire during joining operations
