Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image reading and recording apparatuses with medium transport systems are difficult to move without damaging the installation surface due to their weight and design, making it cumbersome to change their installation position.
Innovation Solution
A medium transport apparatus with a rotating body at its bottom portion that allows the apparatus to switch between a movable state and an installation state, enabling easier movement by rotating or tilting, and including a grip portion for improved operability and posture change.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the apparatus is made heavy and stable for installation, then the installation stability is improved, but the ease of moving the apparatus deteriorates
Solution Approach 1:
The bottom portion of the apparatus is segmented into multiple contact areas including a rotating body and stationary contact areas. This segmentation allows the apparatus to switch between stable installation mode (using all contact areas) and mobile mode (using only the rotating body), resolving the contradiction between stability and mobility.
Solution Approach 2:
The apparatus employs a dynamic bottom structure where the rotating body can rotate between contacting the installation surface and retracting. This dynamic mechanism allows the apparatus to transition from a stable installed state to an easily movable state, addressing the contradiction between installation stability and ease of moving.
2Ease of operation
If the apparatus is dragged to move on the installation surface, then the ease of moving is improved, but the object-affected harmful factors worsen due to surface damage
Solution Approach 1:
The rotating body acts as an intermediary between the apparatus and the installation surface during movement. Instead of dragging the entire apparatus which damages the surface, the rotating body serves as a protective mediator that enables smooth movement while preventing direct contact and potential damage between the apparatus and the installation surface.
3Object-affected harmful factors
If the entire apparatus is lifted and moved, then the installation surface damage is prevented, but the ease of operation deteriorates due to the heavy weight
Solution Approach 1:
The weight-bearing function is segmented between the stationary contact areas (for stable support during operation) and the rotating body (for movement assistance). This segmentation allows the user to move the apparatus more easily by utilizing the rotating body, without needing to lift the entire heavy apparatus, thus maintaining ease of operation while preventing surface damage.
4Ease of operation
If the contact area of the bottom portion is reduced for movement, then the ease of moving is improved, but the installation stability deteriorates
Solution Approach 1:
The contact area of the bottom portion is dynamically adjustable. During movement, only the rotating body contacts the surface providing minimal contact area for ease of moving. During installation, the rotating body rotates to contact the surface alongside stationary contact areas, increasing the total contact area for enhanced stability. This dynamic adjustment resolves the contradiction between ease of moving and installation stability.

AI summary
A scanner is configured to include a rotating body at a bottom portion of an apparatus main body and to be switchable between a movable state in which the rotating body contacts an installation surface on which the apparatus main body is installed and the rotation of the rotating body enables the movement of the apparatus main body on the installation surface and an installation state in which a contact area of the bottom portion of the apparatus main body with respect to the installation surface is larger than the movable state and the apparatus main body is installed and used on the installation surface.
