Solution Overview

Problem

Existing seat fastening arrangements on rail arrangements are complex and cumbersome, lacking simplicity and efficiency in mounting and removal processes.

Innovation Solution

A modular fastening arrangement comprising a lock module, lock unlocking module, and rail unlocking module, allowing for preassemblable components that can be mounted and removed rapidly and simply, with independent or synchronous operation, and featuring an actuating module for easy manipulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a traditional fastening arrangement with hooks or screws is used, then the seat can be fastened on the rail arrangement, but the mounting and removal process becomes complex and time-consuming

Engineering Contradiction:

Improvemounting and removal speedVSAvoidfastening arrangement complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The fastening arrangement is divided into separate functional modules: a lock module with locking elements for securing the seat, an unlocking module for releasing the locks, and a rail module with rail locking means. This segmentation allows each module to be optimized independently and simplifies the overall assembly process, enabling rapid mounting and removal while reducing operational complexity.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If a welded connection is used for nonreleasable fastening, then the connection is strong and reliable, but the seat cannot be removed or repositioned

Engineering Contradiction:

Improveseat repositioning capabilityVSAvoidfastening implementation simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The fastening arrangement transitions from a static welded connection to a dynamic releasable system. The lock module provides a secure fastening state during normal operation, while the unlocking module enables easy release when repositioning is needed. This dynamic design maintains strong connection reliability during use while providing adaptability for seat repositioning and removal.

Inventive Principle:

Principle #15Dynamics

3Reliability

If multiple locking components are used to ensure secure fastening, then the reliability of the connection is improved, but the weight and complexity of the fastening arrangement increase

Engineering Contradiction:

Improvefastening connection reliabilityVSAvoidfastening arrangement weight

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

Multiple locking functions are merged into integrated modules. The lock module combines multiple locking elements that work together to secure the seat to the rail arrangement, while the rail module integrates rail locking means. This merging approach maintains high reliability through redundant locking mechanisms while minimizing overall weight by consolidating components into compact, functional modules rather than using separate heavy components.

Inventive Principle:

Principle #5Merging (Combining)
