Scanner Relay Board Cover for Cable Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing image forming devices, wire members connecting the scanner section and the printer section can be damaged during opening and closing operations, making it difficult to remove them from the scanner section.
Innovation Solution
The image forming device includes a reading device that is openable and closable, with a relay board on its lower surface that covers the upper portion of the device body. The document transport section and control section are electrically connected via a cable, and a relay board cover protects the relay board and the cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wire members are wired inside a cylindrical member to protect them during opening and closing operations, then the reliability of electrical connections is improved, but the ease of removing damaged wire members deteriorates
Solution Approach 1:
The patent divides the electrical connection system into separate segments: the relay board remains fixed in the printer section while the scanner section can be independently removed. The wire members are routed through a groove in the rotary support member rather than being enclosed in a cylindrical member, allowing individual sections to be separated without damaging the connections.
Solution Approach 2:
The patent extracts the wire members from the enclosing cylindrical structure and routes them through the groove in the rotary support member. This allows the wire members to be accessible and removable without requiring removal of a protective cylindrical enclosure, solving both the protection and removability requirements.
2Ease of operation
If the scanner section is made openable and closable for document access, then the ease of operation is improved, but the risk of wire member damage during operation increases
Solution Approach 1:
The patent nests the wire members within the structural groove of the rotary support member, which itself is nested within the scanner section assembly. This nested structure allows the scanner section to open and close for document access while the wire members remain protected within the groove structure throughout the motion range.
Solution Approach 2:
The patent uses the groove structure in the rotary support member as a flexible routing path for the wire members. The groove allows the wire members to flex and move with the opening and closing motion of the scanner section without suffering damage, accommodating the operational movement while protecting the electrical connections.
