Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mini operation tables lack versatility due to a fixed-length table board, which limits their application across various occasions, such as domestic mini scaffolds and vehicle washing, as they either occupy excessive space or require excessive length, compromising portability and cost-effectiveness.
Innovation Solution
The design incorporates a telescopic table board with an eccentric rocker mechanism, allowing the table board to be extended or adjusted in length using a claw clutch and rack system, enabling infinite variable adjustments and convenient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the table board is designed with a fixed length, then the structure is simple and cost-effective, but the versatility is poor and cannot satisfy different application requirements
Solution Approach 1:
The table board is divided into multiple segments (first table board, second table board, third table board) that can slide relative to each other along guide grooves. This segmentation allows the table board to change its effective length by moving segments, thereby improving versatility for different applications while maintaining a relatively simple overall structure.
Solution Approach 2:
The table board transitions from a static fixed-length design to a dynamic adjustable-length design. The guide grooves and sliding mechanisms enable the table board segments to move dynamically, allowing the structure to adapt its configuration based on operational needs, thus resolving the contradiction between simplicity and versatility.
2Length of moving object
If the table board is extended to increase length, then the applicability to vehicle washing is improved, but the storage space requirement increases
Solution Approach 1:
The table board segments are designed to nest within each other when not in use. The first, second, and third table boards can be positioned in a nested configuration where smaller segments fit within or alongside larger segments, significantly reducing the storage space required while maintaining the capability to extend to full length during vehicle washing operations.
Solution Approach 2:
The table board employs dynamic sliding mechanisms through guide grooves that allow segments to move between extended and retracted positions. This dynamic capability enables the table board to achieve maximum length for vehicle washing while collapsing to minimum length for compact storage, resolving the contradiction between operational length and storage volume.
3Adaptability or versatility
If the table board uses a telescopic design with multiple segments, then the versatility is enhanced, but the device complexity increases
Solution Approach 1:
The table board is segmented into multiple independent but coordinated sections (first, second, and third table boards) that slide along guide grooves. Each segment can move independently, providing versatility for different applications while keeping each individual segment relatively simple in design, thus managing overall complexity.
Solution Approach 2:
The telescopic design incorporates dynamic sliding mechanisms with guide grooves that provide controlled movement between segments. This dynamic system allows the table board to adjust its length and configuration for different uses while using straightforward mechanical principles, balancing enhanced versatility with acceptable mechanism complexity.
4Ease of operation
If the table board is made longer for vehicle washing, then the operational convenience is improved, but the portability is reduced
Solution Approach 1:
The table board uses dynamic sliding mechanisms along guide grooves to allow segments to extend to full length during vehicle washing operations, providing operational convenience. When not in use, the same mechanism enables the segments to retract and nest compactly, restoring portability. This dynamic capability resolves the contradiction between operational convenience and portability.
Solution Approach 2:
The table board segments are designed to nest within each other in a compact configuration for portability. During vehicle washing operations, the segments can be extended along guide grooves to provide the necessary length and operational convenience, thus resolving the contradiction between operational convenience and portability through nested storage.
