Solution Overview

Problem

Existing seat attachment devices face challenges in ease of assembly and reusability, particularly in aircraft applications, where secure and efficient connection mechanisms are needed to ensure easy assembly and disassembly for maintenance.

Innovation Solution

A seat attachment device featuring a connection module and a fixing module with detachable coupling points, where the fixing module is designed as a half-shell clamp element and the connection module includes a base body with a slidably connected connection element, allowing for form-fitting engagement and easy assembly, with a connecting element to prevent loss and ensure secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a seat attachment device uses a traditional fixed connection mechanism, then the connection is secure and reliable, but the assembly and disassembly process becomes complex and time-consuming

Engineering Contradiction:
Improveease of assemblyVSAvoidconnection mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The connection mechanism is divided into separate functional modules: a connection module with detachable coupling points and a fixing module with clamp elements. This segmentation allows the assembly process to be simplified into distinct steps while maintaining security, resolving the contradiction between ease of assembly and connection reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection mechanism transitions from a static fixed connection to a dynamic system with detachable coupling points that can be easily engaged and disengaged. The clamp elements can be opened and closed to secure or release the connection, enabling quick assembly and disassembly without complex procedures.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the fixing module is permanently attached to the connection module, then the connection is more secure, but the device loses reusability and requires replacement after each use

Engineering Contradiction:
ImprovereusabilityVSAvoidconnection security
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

A connecting element acts as an intermediary component that temporarily links the fixing module to the connection module during operation. This mediator maintains connection security while allowing both modules to be separated and reused after detachment, resolving the contradiction between reliability and reusability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The detachable coupling points enable the fixing module and connection module to be separated after use, allowing both components to be recovered and reused in subsequent applications. The connecting element can be detached and reattached as needed, maintaining security while ensuring reusability.

Inventive Principle:
Principle #34Discarding and recovering

3Reliability

If the fixing module is completely enclosed around the support element, then the connection is more secure, but the assembly process becomes more difficult and time-consuming

Engineering Contradiction:
Improveconnection securityVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The fixing module is segmented into two separate clamp elements that can be positioned on opposite sides of the support element. This segmentation allows for easier assembly by enabling the clamp elements to be attached independently rather than requiring complete enclosure in a single complex operation, reducing assembly time while maintaining security.

Inventive Principle:
Principle #1Segmentation

AI summary

The invention is based on a seat fastening device, in particular an aircraft seat fastening device, for fastening a seat element (10a; 10c), in particular a seat base, to a carrier element (12a; 12c), with an attachment module (14a, 34a; 14b; 14c; 14d) which, for attachment to the carrier element (12a; 12c), is provided to at least partially enclose the carrier element (12a; 12c) in a circumferential direction in a mounted state. It is proposed that the seat fastening device has a fixing module (16a; 16b; 16c; 16d) which, in the mounted state, is connected to the attachment module (14a, 34a; 14b; 14c; 14d) via at least one releasable coupling point (18a, 20a; 18b, 20b; 18c, 20c; 18d, 20d) and partially encloses the carrier element (12a; 12c).
