Solution Overview

Problem

Existing body-mounted sign carrying systems are cumbersome, heavy, and limit the ability to display multiple messages during protest marches, causing user fatigue and occupying hands unnecessarily.

Innovation Solution

A lightweight shoulder-mounted harness kit that allows for the assembly of up to three sign holders, enabling multiple signs to be carried and displayed without requiring users to manually hold them, using adjustable straps or integrated retainers for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional body-mounted sign carrying systems are used, then signs can be displayed, but the system becomes cumbersome and heavy causing user fatigue

Engineering Contradiction:
Improvesign display capabilityVSAvoidsystem weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The sign carrying system is divided into separate modular components: a lightweight harness body, individual sign holders, and adjustable straps. Each component can be independently configured and assembled, allowing users to carry only the necessary number of signs (one to three) without being burdened by unused equipment weight.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The harness incorporates adjustable straps and flexible retaining mechanisms that can adapt to different body sizes and carrying configurations. The dynamic adjustment capability allows the system to maintain comfort and stability while minimizing the effective weight burden on the user's shoulders and arms.

Inventive Principle:
Principle #15Dynamics

2Reliability

If traditional sign carrying systems are used, then signs can be displayed, but the system is cumbersome and difficult to carry

Engineering Contradiction:
Improvesign display capabilityVSAvoidease of carrying
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system separates the sign holders from the main harness body, allowing signs to be independently attached and removed. This modular design enables users to quickly adjust the number and position of signs without manipulating a complex integrated structure, significantly improving ease of operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The harness is designed with self-adjusting features including automatic strap tensioning and self-retaining sign holders that grip signs without requiring manual fastening mechanisms. Users can independently configure and adjust the system without assistance, making it easy to operate during protest marches.

Inventive Principle:
Principle #25Self-service

3Reliability

If traditional sign carrying systems are used, then signs can be displayed, but hands are occupied and cannot be used for other purposes

Engineering Contradiction:
Improvesign display capabilityVSAvoidhand freedom
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The sign carrying function is extracted from hand-held operation and transferred to a body-mounted system that attaches to the shoulders and back. This extraction completely frees the user's hands from sign-carrying duties while maintaining reliable sign display capability through the harness-mounted holders.

Inventive Principle:
Principle #2Taking out (Extraction)

4Quantity of substance

If traditional sign carrying systems are used, then signs can be displayed, but the system limits the number of messages that can be displayed due to size constraints

Engineering Contradiction:
Improvenumber of signsVSAvoiddisplay area
Core Design Contradiction:
Quantity of substanceVSArea of stationary object

Solution Approach 1:

The system transitions from displaying signs in a single plane (hand-held or chest-mounted) to a three-dimensional configuration around the user's torso. Multiple sign holders are positioned at different locations on the harness (front, sides, back), enabling simultaneous display of multiple messages in different spatial dimensions without increasing the footprint of any single display area.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The harness is designed as a universal platform that can accommodate one to three signs of varying sizes and configurations. The multi-functional design allows the same base system to adapt to different protest needs, whether displaying a single large message or multiple smaller messages simultaneously, maximizing the quantity of information that can be conveyed.

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

AI summary

There is disclosed a kit for assembling a body-mounted sign holder on which one or more signs can be mounted to display multiple messages without engaging a person's hands when the messages on the sign are displayed. There is also disclosed a sign holding device, in particular, one which is lightweight when worn and used, for example, during protest marches.
