Caster Attachment Plate Structure for Heavy Image Forming Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing leg-portion attachment structures for image forming apparatuses face challenges in supporting heavy loads without breaking casters, while also dealing with rocking and increased costs due to the use of high-cost rubber materials with high elastic coefficients.
Innovation Solution
A leg-portion attachment structure featuring a support member with casters and an attachment plate that includes bent portions to absorb impact forces, reducing the load on casters and eliminating the need for coil springs or rubber blocks, thus stabilizing movement and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If coil springs or rubber blocks are interposed between the apparatus main body and casters to suppress rocking, then the rocking of the apparatus main body is suppressed, but the apparatus is upsized and the cost increases
Solution Approach 1:
The patent combines the caster assembly with the support member into an integrated unit, eliminating the need for separate spring or rubber block components. The caster assembly includes a flange portion attached to the support member and a shaft portion with wheels, creating a compact structure that suppresses rocking without additional space-consuming elements.
Solution Approach 2:
The caster assembly is designed to inherently suppress rocking through its structural configuration without requiring external damping components. The flange portion and shaft portion work together to provide stability, allowing the system to self-regulate rocking motion without additional springs or rubber blocks.

4Ease of operation
If the apparatus main body is moved by means of casters, then the apparatus can be easily moved, but the casters may break under heavy load
Solution Approach 1:
The caster assembly is segmented into distinct functional parts: a flange portion for attachment to the support member, a shaft portion for rotation, and wheels for movement. This segmentation allows each component to be optimized for its specific function while working together to handle heavy loads effectively.

The patent combines the caster assembly with the support member into an integrated unit, eliminating the need for separate spring or rubber block components. The caster assembly includes a flange portion attached to the support member and a shaft portion with wheels, creating a compact structure that suppresses rocking without additional space-consuming elements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The structure effectively supports heavy loads without breaking casters, stabilizes movement, and reduces the overall size and cost of the apparatus by using elastic deformation of bent portions to absorb impact and vibration.
Implementation Method 1
a first bent portion formed by bending of an outer edge in the side direction of the caster attachment portion at a predetermined angle

AI summary
A leg-portion attachment structure (100) includes: a support member (110) having a substantially quadrilateral outer periphery and an upper surface on which an apparatus main body (1a) is mounted; two attachment plates (140) provided at two opposite sides on a lower surface of the support member (110). Each of the attachment plates (140) includes caster attachment portions (141) formed respectively on both end sides in a side direction so that casters (130) are firmly attached, first bent portions (142) formed by bending of outer edges in the side direction of the caster attachment portions (141) at predetermined angles, and first coupling portions (143) that are formed by further outward bending of edges of the first bent portions (142) and are firmly attached to the support member (110).
