Telescopic Table Frame Design for Modular Storage and Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing height-adjustable office tables require significant storage space and costs due to the need for prefabricated variants and sizes, as traditional designs restrict legroom and are not modularly efficient.
Innovation Solution
A telescopic table frame composed of complementary metal profiles that can be adjusted longitudinally and laterally, allowing for compact storage and easy assembly into various sizes, featuring a modular structure with offset longitudinal profiles and cross members for stability and aesthetic customization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional welded table frames are used for different table sizes, then structural stability is ensured, but storage space and costs increase significantly
Solution Approach 1:
The table frame is divided into separate modular components (longitudinal profiles, cross members, connecting elements) that can be stored independently in a compact state and assembled when needed, eliminating the need to store multiple complete welded frames for different table sizes
Solution Approach 2:
The modular frame components are designed to nest within each other when collapsed, with longitudinal profiles containing cross members and connecting elements, achieving compact storage volume while maintaining structural integrity during use
2Reliability
If prefabricated table frames for different variants are manufactured, then specific rigidity requirements are met, but manufacturing complexity and inventory costs increase
Solution Approach 1:
A single set of modular frame components can be configured to meet rigidity requirements for multiple table variants and sizes through different assembly arrangements, eliminating the need to manufacture and store multiple specialized prefabricated frames
Solution Approach 2:
The frame structure allows dynamic adjustment and reconfiguration of components to adapt to different rigidity requirements for various table applications, rather than being fixed in a single configuration
3Strength
If traditional table frames are designed, then table top support is provided, but legroom is restricted
Solution Approach 1:
The modular frame design transitions from a rigid two-dimensional planar structure to a three-dimensional configurable structure that can be arranged to provide both adequate table top support and sufficient legroom space through vertical and lateral component positioning
