Passenger Seat Armrest Guide Element Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional passenger seats with adjustable armrests often fail to ensure horizontal support surface adjustability based on body size and sitting position, require complex constructions, and restrict legroom due to installation space, leading to increased costs and weight, as well as impaired freedom of movement.
Innovation Solution
A seat design featuring a support structure with a guide element on the backrest for linear displacement of the armrest, allowing height adjustment and integration into the seat's support structure, eliminating the need for separate construction means and swivel joints, which impairs legroom.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional adjustable armrest designs are used, then armrest adjustability is provided, but device complexity increases and installation space is required that restricts legroom
Solution Approach 1:
The guide element is integrated directly into the support structure of the seat, merging the armrest guidance function with the existing support structure. This eliminates the need for separate construction means and large adjustment joints, thereby reducing device complexity while maintaining armrest adjustability
Solution Approach 2:
The support structure serves multiple functions: it provides structural support for the seat and simultaneously integrates the guide element for armrest height adjustment. This multi-functionality reduces the need for additional components and simplifies the overall construction
2Adaptability or versatility
If separate armrest modules are manufactured and assembled, then armrest functionality is provided, but manufacturing costs and weight increase
Solution Approach 1:
The armrest mechanism is integrated with the support structure through the guide element, eliminating the need for separate armrest modules. This integration reduces the number of parts, simplifies assembly, and decreases the overall weight of the armrest assembly
Solution Approach 2:
The guide element is extracted as a functional component integrated into the support structure, allowing the armrest to be mounted directly without requiring separate construction means. This extraction simplifies the overall design and reduces weight
3Adaptability or versatility
If swivel joints are used for armrest adjustment, then armrest position flexibility is provided, but freedom of movement for person behind is restricted
Solution Approach 1:
The guide element is integrated into the support structure, merging the armrest mounting function with the existing structure. This integration eliminates the need for swivel joints and large adjustment mechanisms, thereby preserving legroom and freedom of movement for the person behind
