Scanner Cable Interference via Side Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sheet feed type scanners, cables such as power and communication cables often interfere with the rotation of the apparatus main body due to their positioning, causing hindrances and making it difficult to change the posture of the scanner.
Innovation Solution
The image reading apparatus includes a main body supporting portion that rotatably supports the apparatus main body, with coupling portions positioned on the side intersecting the rotation shaft, allowing cables to be securely managed and preventing them from hindering rotation. This configuration includes a motor and a rotation converting section for effortless posture switching, optimizing cable placement and reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If coupling portions are positioned on the front or rear of the apparatus main body, then cable connection is convenient, but cables interfere with rotation and hinder posture change
Solution Approach 1:
The coupling portions are repositioned from the front/rear directions to the left/right side directions of the apparatus main body. This spatial reconfiguration in a different dimension allows cables to be routed away from the rotation path, eliminating interference while maintaining connection accessibility.
2Adaptability or versatility
If apparatus main body is made rotatable for multiple postures, then versatility is improved, but cable interference increases
Solution Approach 1:
The coupling portions are extracted from their traditional front/rear positions and relocated to the side positions. This separation removes the cables from the rotational interference zone, allowing the apparatus main body to rotate freely through multiple postures without cable hindrance.
3Object-affected harmful factors
If coupling portions are positioned on the side intersecting rotation shaft, then cable interference is reduced, but connection accessibility may be affected
Solution Approach 1:
By moving coupling portions to the side directions (left/right) which intersect the rotation shaft, the design exploits a different spatial dimension that is perpendicular to the rotation arc. This positioning places cables outside the interference zone while maintaining reasonable accessibility from the sides.
