Solution Overview

Problem

Students often face challenges while waiting for transportation due to the lack of comfortable and sanitary seating options, leading to physical discomfort and soiled clothing when sitting on the ground.

Innovation Solution

A backpack chair device with a folding seat assembly that includes a backrest, seat, and legs, which can be easily deployed and secured using hinges and straps, allowing the user to sit off the ground surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a student carries a traditional backpack without seating functionality, then the backpack remains lightweight and simple, but the student has no seating option when waiting for transportation

Engineering Contradiction:

Improveseating functionalityVSAvoidbackpack structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines a backpack with an integrated folding chair mechanism, merging two separate functions (carrying and seating) into a single device. The chair assembly including seat, backrest, and legs is integrated within the backpack structure, allowing the student to transition from carrying mode to seating mode without requiring separate items.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The folding chair mechanism is nested within the backpack structure. When collapsed, the chair components are contained within the backpack body or integrated into its framework. The seat, backrest, and legs are stored in a compact configuration inside the backpack, similar to nested dolls, maximizing space efficiency.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Object-affected harmful factors

If a student sits on the ground while waiting for transportation, then no additional device is needed, but the student's clothing becomes soiled and they experience physical discomfort

Engineering Contradiction:

Improvesoiled clothing and physical discomfortVSAvoidbackpack structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The chair assembly acts as an intermediary between the student and the ground surface. Instead of direct contact between the student and the potentially contaminated ground, the chair provides an elevated seating platform with legs that extend to the ground, creating a protective barrier that prevents soiling and reduces physical discomfort.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If a backpack chair device is designed with full chair assembly (seat, backrest, legs), then seating comfort is improved, but the device weight and size increase

Engineering Contradiction:

Improveseating comfortVSAvoidbackpack weight

Core Design Contradiction:

Ease of operationVSWeight of moving object

Solution Approach 1:

The chair assembly is designed with movable and collapsible components that can transition between extended and retracted states. The legs can be extended to the ground when needed and retracted into the backpack structure when not in use. The backrest and seat can be folded flat against each other, allowing the system to adapt its configuration based on whether seating is required, thereby reducing weight and size during transport.

Inventive Principle:

Principle #15Dynamics
