Rotary Seat Mounting Fitting for Tool-Free Reorientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting systems for objects like seats in vehicles or aircraft require complex and time-consuming processes to remove and reorient, often needing specialized tools and multiple fittings, which complicates quick and easy installation and reconfiguration.
Innovation Solution
A mounting fitting with a rotatable locking and release mechanism, featuring radially extending pins and a pre-loaded spring, allows for easy detachment and reorientation of the seat by manual rotation without tools, using a single fitting for different orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mounting systems with multiple fittings and fasteners are used, then reliable attachment is achieved, but removal and reorientation become complex and time-consuming requiring specialist tools
Solution Approach 1:
The mounting fitting is divided into two distinct portions: a first portion that attaches to the object (seat) and a second portion that attaches to the surface (floor). These portions can be independently manufactured and assembled, simplifying the overall system while enabling easy separation and reconfiguration without requiring specialist tools or complex disassembly procedures.
Solution Approach 2:
The single mounting fitting is designed to provide multiple functions: it can securely attach the seat to the floor, allow quick removal, and enable reorientation of the seat. The fitting incorporates a locking and release mechanism with pins and L-shaped grooves that work together to achieve reliable attachment while simultaneously providing easy manual operation for reconfiguration, eliminating the need for multiple different fittings or specialized tools.
2Adaptability or versatility
If multiple fittings are provided for different orientations, then adaptability is improved, but device complexity and cost increase
Solution Approach 1:
The mounting fitting incorporates a dynamic locking and release mechanism that allows the first portion to be rotated relative to the second portion. The pins extending radially from the first portion engage with L-shaped grooves in the rotatable knob, enabling the user to manually rotate and lock the fitting at different orientations. This dynamic mechanism provides adaptability for different seat orientations using a single universal fitting rather than requiring multiple static fittings for each orientation.
3Reliability
If traditional fastening systems are used, then secure attachment is achieved, but removal time increases
Solution Approach 1:
The mounting fitting incorporates a pre-loaded spring that maintains constant engagement pressure between the pins and the L-shaped grooves. This preliminary action ensures that the attachment is securely locked in place during normal use, while the rotatable knob mechanism is pre-configured to allow quick manual rotation and release. The spring-loaded design provides reliable attachment without requiring tight fasteners or complex locking procedures, enabling rapid removal and reconfiguration.

AI summary
A mounting fitting includes fitting comprising a first portion configured to be attached to a object, in use, and a second portion configured to be attached to a surface, in use, and further comprising a locking and release mechanism configured to releasably lock the first portion relative to the second portion, the locking and release mechanism including one or more pins a rotational knob located between the first portion and the second portion via a pre-loaded spring and having one or more L-shaped grooves configured to lockingly receive the one or more pins in the one or more grooves when the knob is in a first rotational position, the rotational knob being rotatable relative to first and second portions to a second rotational position in which the one or more pins can be removed axially from the one or more grooves to remove the first portion from the second portion.
