Solution Overview

Problem

Existing vehicle seating systems lack ease of assembly and reconfiguration, particularly in motorcycles and open-air vehicles, where seating arrangements often vary and require convenient changes.

Innovation Solution

A modular seating assembly system for vehicles, allowing easy conversion between one and two seating positions, utilizing interchangeable brackets and fasteners to secure seat pans to a fender assembly, with reinforced openings and grab straps for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a common frame is used for various motorcycle models with different seating arrangements, then manufacturing cost and frame design complexity are reduced, but the ability to easily reconfigure seating from one to two positions is compromised

Engineering Contradiction:
Improveseating configuration adaptabilityVSAvoidseating assembly reconfiguration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The seating assembly is divided into separate modular components: a first seat pan for the operator and a second seat pan for the passenger, each with their own brackets and fasteners. This segmentation allows the second seat pan to be independently installed or removed, enabling easy reconfiguration between one and two seating positions without affecting the common frame structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The seating system employs removable and reconfigurable fasteners that allow dynamic adjustment of the seating configuration. The fasteners can be quickly installed or removed to convert the seating arrangement from a two-seat configuration to a one-seat configuration, providing operational flexibility without permanent modifications.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If seating arrangements are made easily reconfigurable between one and two positions, then customer convenience and adaptability are improved, but structural integrity and secure attachment may be compromised

Engineering Contradiction:
Improveseating reconfiguration easeVSAvoidseat attachment reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The brackets are pre-configured with reinforced openings and the fasteners are designed with specific engagement features before assembly. The second bracket is pre-positioned on the common frame at the desired location, and the reinforced openings are prepared in advance, allowing for quick installation while ensuring structural integrity from the start of the assembly process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The bracket design incorporates reinforced openings that combine multiple structural elements to maintain strength while allowing fastener passage. The reinforcement structures are integrated into the bracket material composition, providing both the necessary opening for easy attachment and the structural integrity required for reliable seat support.

Inventive Principle:
Principle #40Composite materials

3Adaptability or versatility

If multiple seating configurations are provided on a common frame, then vehicle versatility is improved, but the time and complexity of assembly and disassembly increase

Engineering Contradiction:
Improveseating configuration optionsVSAvoidseating assembly time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The common frame is designed with universal mounting locations and standardized bracket interfaces that can accommodate different seating configurations. The same frame structure supports both one-seat and two-seat arrangements using the same basic mounting points, reducing assembly time by eliminating the need for different frame modifications for different configurations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The fasteners are designed as simple, easily replaceable components that can be quickly installed and removed without specialized tools or complex procedures. This approach prioritizes rapid reconfiguration over permanent, highly durable fastening mechanisms, allowing customers to easily change seating arrangements without significant time investment.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
