Connecting device for anchoring seat modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture anchoring devices require lateral displacement for connection, which can be impractical in spaces with limited lateral access, restricting the ability to connect modules in directions other than laterally.
Innovation Solution
A ratchet device with an articulated arm and cylindrical pivot allows for connection in any direction by using a serrated slot and pivot that can be inserted and extracted in a transverse plane, with a rotating mechanism and adjustable stops to accommodate different orientations, enabling connection and disconnection in various directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a triangular prismatic tip is inserted into a serrated slot in a lateral direction, then secure anchorage is achieved, but the device requires sufficient lateral space for insertion which is not available in many rooms
Solution Approach 1:
The patent changes the insertion dimension from lateral (horizontal) to longitudinal (vertical). The serrated slot is oriented vertically along the longitudinal axis of the end, allowing the triangular prismatic tip to be inserted by moving modules together in the longitudinal direction rather than laterally. This dimensional change resolves the space constraint while maintaining anchorage security through the same serrated engagement mechanism.
2Reliability
If modules are connected by lateral displacement with the slot opening facing the tip frontally, then proper anchorage is achieved, but connection in other directions is not possible without affecting component state
Solution Approach 1:
The patent reorients the serrated slot from a lateral opening to a longitudinal orientation along the module's length. This allows the triangular prismatic tip to engage the slot by moving modules together in the longitudinal direction, enabling connection without lateral displacement and accommodating various connection directions while ensuring proper anchorage through the serrated engagement.
Solution Approach 2:
The connecting device is designed to accommodate multiple connection directions and module orientations. The longitudinal serrated slot combined with the triangular prismatic tip creates a universal connection interface that can engage regardless of the specific directional approach, making the device adaptable to different furniture arrangements and space configurations.
3Reliability
If the serrated slot is open at one end with teeth preventing lateral extraction, then secure anchorage is achieved, but the device complexity increases with the need for specific insertion orientation
Solution Approach 1:
The patent repositions the serrated slot opening from a lateral face to the longitudinal end of the module. The slot extends vertically along the longitudinal axis with teeth oriented to prevent longitudinal extraction rather than lateral extraction. This reconfiguration simplifies the insertion process by aligning the opening with the primary movement direction while maintaining the one-way anchorage function through the serrated teeth.
