Marching Carrier Adjustable Cushions Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional marching carriers concentrate the load of a musical instrument on specific parts of the player's back and shoulders, leading to discomfort and increased load, as they do not provide sufficient adjustable contact areas to distribute the weight evenly.
Innovation Solution
A marching carrier design featuring a carrier main body with adjustable shoulder and back cushions that pivot to fit the player's body shape, allowing for customizable angles and positions to distribute the load more evenly across the shoulders and back.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an integrated marching carrier with fixed shoulder portion is used, then the musical instrument can be reliably supported, but the load concentrates on specific positions such as shoulders and back, increasing the load on the player
Solution Approach 1:
The marching carrier is divided into separate components: a frame structure and independently adjustable shoulder straps and back cushions. This segmentation allows each component to be optimized and adjusted separately, enabling the shoulder straps and back cushions to conform to the player's body shape independently, thereby distributing the load more evenly across multiple contact points rather than concentrating it on fixed positions.
Solution Approach 2:
The shoulder straps and back cushions are designed with adjustable angles relative to the frame, allowing dynamic adaptation to different player body shapes and sizes. This adjustability enables the contact surfaces to be positioned optimally for each player, transforming the static load distribution of fixed carriers into a dynamic system that can be customized to distribute weight evenly across the shoulders and back.
2Object-affected harmful factors
If the shoulder portion shape is made adjustable according to the player's body, then the load on the player can be lightened, but the carrier structure becomes more complex
Solution Approach 1:
The carrier employs adjustable shoulder straps and back cushions that can be positioned at different angles relative to the frame, allowing adaptation to various body shapes without requiring a completely redesign of the overall structure. This dynamic adjustability achieves load distribution benefits while maintaining a relatively simple underlying frame structure.
Solution Approach 2:
The frame structure serves as a universal base that supports multiple configuration options for the shoulder straps and back cushions. This multi-functional design allows the same frame to accommodate different strap angles and cushion positions, providing adaptability to various players without requiring multiple specialized carrier designs, thus balancing complexity with versatility.
3Device complexity
If the carrier cannot be adjusted separately for different body parts, then the structure remains simple, but insufficient contact areas are obtained depending on the shapes of back and shoulders
Solution Approach 1:
The carrier separates the adjustment functions for different body parts by providing independent adjustment mechanisms for shoulder straps and back cushions. Each component can be adjusted separately to match the contours of the player's shoulders and back, maximizing the contact area at each location without requiring complex integrated adjustment systems.
Solution Approach 2:
The independent adjustability of shoulder straps and back cushions allows each component to be dynamically configured to match the player's specific body shape. This creates sufficient contact areas at both the shoulder and back regions by allowing separate optimization of each contact point, rather than relying on a single fixed structure.

AI summary
A marching carrier includes rods for supporting a musical instrument, a carrier main body to be in contact with a front face of a trunk of a player, a frame put on both shoulders of the player, a pair of shoulder cushions pivotably attached to the frame, and a back cushion pivotably attached to the frame. In the marching carrier, angles of the shoulder cushions and the back cushion to the frame can be adjusted separately.
