Spring bearing beam and frame of a laundry treatment apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry treatment apparatuses have complex internal structures leading to inefficient assembly processes and increased production costs due to asymmetrically designed spring bearing beams that are prone to detachment during transportation or movement, requiring time-consuming adjustments during assembly.
Innovation Solution
A spring bearing beam with symmetrically arranged first and second connection structures on its upper and lower sides, respectively, allowing for interchangeable left and right sides, reducing the need for side differentiation and improving fixing stability by using both structures for assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only one fixing structure (screw hole) is disposed on one side of the spring bearing beam, then the structure is simple, but the fixation effect is poor and the spring bearing beam is easily detached during transportation or movement
Solution Approach 1:
The fixing structure is segmented into multiple connection structures (first connection structure and second connection structure) distributed at different locations on the spring bearing beam. This segmentation allows the beam to be fixed at multiple points, significantly improving fixation reliability while maintaining reasonable structural complexity.
Solution Approach 2:
Different connection structures are applied at different locations on the spring bearing beam based on local fixing requirements. The first connection structure is disposed on one side and the second connection structure on another side, with each structure optimized for its specific location to achieve uniform and reliable fixation throughout the beam.
2Ease of manufacture
If the spring bearing beam is asymmetrically designed, then the connection structures can be optimized for specific functions, but the operator needs to adjust locations of front side, back side, left side, and right side during assembly, increasing assembly time
Solution Approach 1:
The spring bearing beam employs asymmetric design with different connection structures at different locations to optimize for specific functional requirements. The first connection structure and second connection structure have different configurations suited for their respective positions, achieving manufacturing optimization while the patent addresses the assembly time issue through clear structural differentiation.
Solution Approach 2:
Instead of requiring operators to remember and adjust for asymmetric orientations, the design inverts the approach by making the connection structures themselves clearly differentiated and position-specific, so that proper installation becomes self-evident through the structure's own configuration rather than requiring external orientation knowledge.
3Reliability
If the spring bearing beam is fixed to reinforcing members on the frame by using both first connection structure and second connection structure, then the fixing stability is improved, but the assembly process becomes more complex
Solution Approach 1:
The fixing process is segmented into multiple independent connection structures that can be installed separately. The first connection structure and second connection structure are disposed at different locations and can be fixed independently, improving fixing stability while allowing flexible assembly sequencing that may actually simplify the overall assembly process.
Solution Approach 2:
Multiple connection structures are merged into a unified spring bearing beam design, where the first connection structure and second connection structure work together to provide enhanced fixing stability. The structures are integrated into the beam's overall design, creating a cohesive assembly process rather than separate, complex operations.

AI summary
A frame of a laundry treatment apparatus includes a spring bearing beam, which includes a body with a strip-shape, a first connection structure is disposed on an upper side of the body, a second connection structure is disposed on a lower side of the body, and the body is fixedly connected with a reinforcing member arranged on the frame via the first connection structure and/or the second connection structure. Preferably, the first connection structure and the second connection structure are symmetrically disposed on the upper side and the lower side of the body. A left side and a right side of the spring bearing beam are used interchangeably, and in an actual assembly process, there is no need to differentiate between the left and the right positions of the spring bearing beam, and only a back side and a front side of the bearing beam need differentiation.
