Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing duplex scanners are costly due to the complexity of their mechanisms, whether they use a single scanning module with a complicated sheet passage and transporting mechanism or two scanning modules with a simpler passage and mechanism.
Innovation Solution
A duplex scan indicative scanner design utilizing a single scanning module, a sheet passage, a transporting mechanism, a duplex indicator, and a connection interface, where the electronic device controls the scanning module and duplex indicator to guide the user in scanning both sides of a document, reducing complexity and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single scanning module with a complicated sheet passage and transporting mechanism is used, then duplex scanning function is achieved, but device complexity and cost increase
Solution Approach 1:
Instead of using a single scanning module with a complicated turn-over passage to scan both sides, the patent inverts the approach by using two simple scanning modules positioned at different locations to scan the front and back sides simultaneously or sequentially, eliminating the need for document flipping and complex transporting mechanisms
Solution Approach 2:
The patent divides the duplex scanning function into two separate scanning operations performed by two independent scanning modules, each responsible for scanning one side of the document. This segmentation allows each module to be simpler and eliminates the need for a single complex module with turn-over capabilities
2Adaptability or versatility
If two scanning modules are used with simpler transporting mechanism, then duplex scanning function is achieved, but device cost increases
Solution Approach 1:
Each scanning module is designed to be multi-functional, capable of scanning both color and grayscale images, and can operate independently or in combination with the other module. This universality allows the system to achieve duplex scanning without requiring specialized expensive modules
Solution Approach 2:
The patent merges the control functions of two scanning modules into a single integrated controller that manages both modules, coordinates their operations, and processes the scanned data from both sides, reducing overall system complexity and cost despite using two scanning modules

AI summary
A duplex scan indicative scanner includes a sheet passage, a transporting mechanism, one single scanning module, a duplex indicator and a connection interface. The transporting mechanism transports a document past the sheet passage. The scanning module scans a first side of the document passing through the sheet passage. The connection interface is electrically connected to an electronic device, the duplex indicator, the transporting mechanism and the scanning module. After the electronic device has controlled, through the connection interface, the scanning module to scan the first side, the electronic device controls, through the connection interface, the duplex indicator to output a duplex indication message to guide a user to place the document or a second document, so that a second side of the document or the second document is scanned by the scanning module. A duplex scan indicative scanning apparatus and a duplex scan indicative scanning method are also provided.
