Overlapping Cable Cover for Rotating Image Forming Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face challenges in displaying vertically or horizontally long images on a rectangular screen without compromising visibility, as rotating the image orientation often results in reduced visibility or misalignment.
Innovation Solution
A support mechanism that allows the display unit to rotate between horizontally-long and vertically-long attitudes, coupled with a cable cover that expands and contracts to accommodate the rotation, ensuring the cable is protected and does not interfere with the display unit's movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display unit is rotated to display vertically long images, then the visibility of print targets is improved, but the cable may interfere with the rotation movement or become damaged
Solution Approach 1:
The cable cover is divided into multiple element cover members (first element cover member and second element cover member) that can move independently. This segmentation allows each segment to accommodate the cable's movement during rotation while maintaining continuous protection
Solution Approach 2:
The cable cover transitions from a static structure to a dynamic one where the element cover members can change their overlapping state during rotation. The cover expands when the display unit is in horizontally-long attitude and contracts when in vertically-long attitude, adapting to the cable's position throughout the rotation range
2Reliability
If a rigid cable cover is used to protect the cable, then the cable protection is improved, but the cable cover cannot accommodate the rotation movement of the display unit
Solution Approach 1:
The cable cover employs dynamic element cover members that can change their configuration during rotation. The overlapping state between the first and second element cover members varies as the display unit rotates, allowing the cover to expand and contract while maintaining continuous cable protection throughout the movement range
Solution Approach 2:
The cable cover functions as a flexible protective structure where the element cover members can adjust their relative positions. This flexibility allows the cover to accommodate the cable's movement during rotation while maintaining its protective function, unlike a rigid cover that would constrain the movement
3Volume of moving object
If the cable cover is designed to be compact, then the device size is reduced, but the cable may be exposed or damaged during rotation
Solution Approach 1:
The element cover members are arranged in an overlapping configuration where the second element cover member is positioned within or alongside the first element cover member. This nesting arrangement allows the cable cover to maintain a compact form factor while ensuring continuous cable protection during rotation movements
Solution Approach 2:
The cable cover uses dynamic overlapping element cover members that adjust their configuration during rotation. This allows the cover to maintain a compact size when not in use while expanding sufficiently during rotation to protect the cable, and contracting back to a compact state afterward

AI summary
A cable cover covers a portion of a cable ranging from a swing member to a main body. The cable cover includes a plurality of element cover members which are arranged while sequentially overlapping each other and are coupled while being capable of changing an overlapping state thereof. The plurality of element cover members include a first element cover member coupled to the swing member, and one or a plurality of second element cover members supported by the support shaft while being rotatable about a tilt axis line. By the plurality of element cover members partially rotating in conjunction with a rotation of the swing member and the overlapping state of the plurality of element cover members thus being changed, the cable cover is capable of expanding and contracting in accordance with the rotation of the swing member.
