Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for personal armrests in cramped public transportation fail to provide adequate ergonomic support, storage, and adjustability, leading to discomfort and conflicts with neighboring passengers.
Innovation Solution
A wearable personal armrest device with a chest portion and adjustable shoulder straps that accommodates arms in front of the body, featuring a tubular cavity, padded materials for comfort, and a resealable pouch for storage, designed to maintain arm position and prevent slouching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a portable arm rest divider is used to expand surface area and provide separation, then personal space division is improved, but device complexity and lack of ergonomic support worsen
Solution Approach 1:
The arm support device is divided into multiple functional segments: a chest support portion, separate arm pockets, and adjustable straps. This segmentation allows each component to perform its specific function independently while contributing to the overall solution, resolving the contradiction by providing adequate surface area without excessive complexity.
Solution Approach 2:
The invention transitions from a two-dimensional flat armrest divider to a three-dimensional wearable chest support system with volumetric arm pockets. This dimensional change provides adequate support surface area while integrating the structure into the wearer's body space, avoiding the complexity of large external structures.
2Stability of the object's composition
If rigid arm support structures are used to maintain arm position, then arm position stability is improved, but comfort and adaptability worsen
Solution Approach 1:
The arm support device incorporates adjustable straps with buckles that allow dynamic adaptation to different body sizes and arm positions. The soft, flexible materials enable the structure to conform to various users while maintaining stable arm positioning through customizable tension, resolving the contradiction between stability and adaptability.
Solution Approach 2:
The device allows parameter changes in strap length and tension to adapt to different users and conditions. By varying these parameters, the device maintains stable arm support while accommodating diverse body types and comfort preferences, resolving the contradiction between stability and versatility.
3Object-affected harmful factors
If arm support devices are worn close to the body, then personal space maintenance is improved, but ergonomic support and storage capability worsen
Solution Approach 1:
The arm pockets are nested within the chest support structure, creating a compact wearable device that maintains personal space while providing adequate arm support. The nested design integrates multiple functions (support, positioning, and potential storage) within a space-efficient configuration that doesn't encroach on neighboring passengers.
Solution Approach 2:
The chest support device serves multiple functions: it provides ergonomic arm support, maintains personal space boundaries, and offers potential storage capability through the structured chest portion. This multi-functionality resolves the contradiction by delivering comprehensive ergonomic support despite the compact wearable form factor.
4Adaptability or versatility
If adjustable straps are added to improve fit, then adaptability is improved, but device complexity worsens
Solution Approach 1:
The adjustment mechanism is extracted as a separate, simple buckle system independent of the main support structure. This allows adaptability to be added without significantly increasing the complexity of the core arm support function, as the straps can be adjusted without affecting the structural integrity or support quality.

AI summary
A traveler's personal arm rest device comprises a chest portion and a pair of shoulder straps configured to supportively maintain the chest portion against the anterior side of a wearer's torso. In an embodiment, the chest portion may be securely folded to define a tubular cavity sized to accommodate all of the wearer's arms therein so that such arms may be maintained and comfortably supported by way of the straps in a resting position that is in line with his or her own body. The disclosure may provide a wearer with increased comfort while seated in cramped modes of public transportation and further prevent passive aggressive and even assertive arguments with neighbors regarding available arm resting spaces. Elements enabling compact self-stowage when not in use, providing ergonomic support when worn, and permitting storage of personal belongings therein are also provided.
