Frame Unit Cutout Routing for Flexible Member Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly process of electric apparatuses with a lower and upper structure is hindered when a flexible member is routed through a corner of the lower structure, leading to reduced assembly freedom and potential deformation due to the weight of the upper structure.
Innovation Solution
A frame unit design featuring a first member with a cutout portion and a second member with a protruding portion that enters the cutout when attached, maintaining assembly freedom and preventing deformation by ensuring the cutout width remains stable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cutout portion is formed in the frame to route the flexible member, then assembly freedom is improved, but the frame may become deformed due to the weight of the upper structure
Solution Approach 1:
The frame is divided into two separate members: a first member containing the cutout portion for routing the flexible member, and a second member that serves as a support structure. This segmentation allows the first member to provide routing freedom while the second member provides structural support to prevent deformation under weight loads.
Solution Approach 2:
The second member acts as an intermediary support structure between the first member and the upper structure. By positioning the second member to face the first plate portion with its facing portions aligned with the receiving portions, it provides mechanical support that prevents the first member from deforming under the weight of the upper structure while still allowing the flexible member to pass through the cutout.
2Ease of operation
If an opening portion is formed in the lower structure to route the flexible member, then assembly freedom is improved, but the process is set and degree of freedom in assembly process is reduced
Solution Approach 1:
By segmenting the frame into two separate members with specific functional divisions, the design allows the first member to provide a cutout portion that facilitates flexible member routing without imposing the same assembly constraints as a single integrated opening portion would require.
Solution Approach 2:
The cutout portion is extracted from the traditional opening portion design. Instead of forming a large opening that requires specific assembly procedures, only a minimal cutout is created in the first member, which can be easily routed through without constraining the assembly process of other components.

AI summary
A frame unit includes a first member formed with a cutout portion, and a second member to be fixed to the first member. A first receiving portion and a second receiving portion are formed in the cutout portion, the second member includes a first facing portion facing the first receiving portion, a second facing portion facing the second receiving portion, and a protruding portion protruding toward the first plate portion. When the second member is attached to the first member, the protruding portion enters the cutout portion so that the first facing portion faces the first receiving portion and the second facing portion faces the second receiving portion.
