Claw-Latch Chair and Stool Base for Flexible Seating Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-functional seating designs often compromise on user-friendliness and versatility, either being overly complex or too specialized, failing to meet the diverse needs of active users in various environments, particularly in smaller spaces where flexibility and simplicity are desired.
Innovation Solution
A chair with a coupling companion stool base that features a frame with a claw and latch mechanism, allowing for easy reconfiguration between task seating and casual rocker seating, with a base that can function as a stool or side table, incorporating a tilt and swivel mechanism for adaptability and user feedback through audible engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multi-functional seating designs attempt to address many common functional needs, then versatility is improved, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The seating unit is divided into two main segments: a chair portion with frame and sitting portion, and a separate base portion. These segments can be coupled together for task seating or separated for casual seating, allowing functional versatility without requiring a single complex integrated structure. The segmentation enables each part to be optimized independently while providing multiple configuration options.
Solution Approach 2:
The base portion is designed with universal functionality to serve multiple purposes: it can function as a companion stool for seating, a side table for placing items, or simply as a structural support base. This universal design allows the same component to fulfill different functional needs across various seating configurations, enhancing versatility without adding complexity.
2Adaptability or versatility
If multi-functional seating designs attempt to address many common functional needs, then versatility is improved, but ease of operation deteriorates due to requiring notable user involvement and mechanical aptitude
Solution Approach 1:
The coupling mechanism incorporates dynamic elements including a tilt mechanism that allows the seat to tilt relative to the base, and a swivel mechanism that enables rotational movement. These dynamic features allow users to easily adjust the seating position and orientation without requiring mechanical aptitude, making the versatile functionality intuitive and easy to operate.
Solution Approach 2:
The latch mechanism is designed to automatically engage and disengage the coupling between the chair portion and base portion through simple user actions. The system provides self-service functionality where the mechanical components guide the user through the coupling process, reducing the need for user involvement and mechanical knowledge while maintaining ease of operation.
3Adaptability or versatility
If the base is designed to function as a companion stool or side table, then versatility is improved, but device complexity increases
Solution Approach 1:
The base portion is designed with universal functionality to serve multiple purposes: it can function as a companion stool for seating, a side table for placing items, or simply as a structural support base. This universal design allows the same component to fulfill different functional needs across various seating configurations, enhancing versatility without adding complexity.

AI summary
A chair with a coupling companion stool base includes a frame that has: a claw extending downward from a second portion of a lower portion of the frame; a latch extending downward from and movably connected with a first portion of the lower portion; two legs adapted to support the frame upon a supporting surface extending downward from the lower portion; and a receptacle defined between the claw and the latch. The base supports the frame above a supporting surface and has a saddle with opposite back and front edges and a top surface that faces away from the supporting surface. The top surface may also define at least one of a work surface, a writing surface, and a sitting surface. The base releasably couples with the frame, having the saddle seated in the receptacle, the front edge seated in the claw, and the back edge captured by the latch. When decoupled, the chair portion may be used as casual floor rocker seating.
