Table Frame Snap-Fit Assembly to Replace Screw Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional table assembly configurations are inconvenient for end users due to reliance on multiple screws for stability, making packaging and shipping inefficient and requiring complex assembly processes.
Innovation Solution
An assembly-friendly table frame design featuring a connecting member with an insert-fitting rail and locking slot, where a locking bump is inserted and snapped into place, allowing for tool-free assembly and disassembly using an ejector member, replacing traditional screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fastening screws are used to connect uprights and base stands, then stability is improved, but assembly convenience deteriorates
Solution Approach 1:
The patent replaces the traditional screw fastening system with a bump-lock mechanism consisting of a connecting member with a locking slot and a locking bump. This mechanical substitution eliminates the need for screws while maintaining connection stability, allowing for tool-free assembly by simply inserting and snapping the locking bump into the locking slot.
Solution Approach 2:
The invention extracts and removes the screws from the connection system, replacing them with an integrated bump-lock structure. By taking out the screw fastening method and substituting it with a snap-fit locking mechanism, the design achieves both stability and assembly convenience without requiring external fastening elements.
2Strength
If multiple screws are used to enhance stability, then connection strength is improved, but device complexity increases
Solution Approach 1:
The patent merges the locking function and the connecting function into a single integrated bump-lock mechanism. The locking bump and locking slot work together as a unified system, combining multiple functions (positioning, locking, and connection) into one simple structure, thereby reducing assembly complexity while maintaining connection strength.
Solution Approach 2:
The invention substitutes the multi-screw fastening system with a single bump-lock mechanism. This replacement reduces the number of components and assembly steps while providing sufficient connection strength through the interlocking geometry of the locking bump and slot, thereby reducing device complexity.
3Volume of moving object
If base stands are packaged separately from uprights to reduce package size, then shipping efficiency is improved, but assembly difficulty increases
Solution Approach 1:
The patent replaces complex screw assembly with a simple bump-lock mechanism that requires only insertion and snapping actions. This simplified mechanical system makes separated packaging feasible while maintaining easy assembly, as users can connect the uprights and base stands without requiring tools or complex procedures.
Solution Approach 2:
The bump-lock mechanism is designed to be self-assembling through a simple snap-fit action. The locking bump automatically engages with the locking slot when the components are brought together, providing a self-service assembly experience that eliminates the need for tools or complex procedures, thereby making separated packaging practical.

AI summary
Disclosed is an assembly-friendly table frame, which relates to the field of lift tables. The table frame includes an upright and a base stand mounted to the underside of the upright; one of the base stand or the upright is securely coupled with a connecting member, and the other thereof is provided with a locking bump; the connecting member includes an insert-fitting rail and a locking slot provided in the insert-fitting rail; the locking bump is sequentially inserted into the insert rail and slid to be snapped into the locking slot; the table frame further includes an ejector member configured to eject the locking bump out of the locking slot. Further disclosed is a table applying the table frame. An advantage of the present disclosure lies in enhancing convenience of assembly and disassembly between the upright and the base stand.
