Backpack Mesh Net with Spring-Biased Ball Members for Ventilation and Massage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional backpacks do not effectively improve ventilation or address fatigue when worn for long periods, lacking a health-promoting effect.
Innovation Solution
A backpack design featuring a metal frame with a mesh net and ball members supported by springs, which provides ventilation by maintaining a distance between the back plate and the wearer's back, while the ball members offer a massaging effect by applying pressure on specific points, improving comfort and reducing fatigue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a mesh net is provided apart from the storage part, then ventilation is improved, but the backpack does not address fatigue accumulation when worn for long time
Solution Approach 1:
The mesh net is configured to serve dual functions: providing ventilation through its porous structure and offering massaging effects through protruding portions that stimulate acupoints on the wearer's back. This multi-functional design resolves the contradiction by integrating both ventilation and health-promoting capabilities into a single component.
Solution Approach 2:
The invention combines the ventilation function and the massaging function into a single integrated mesh net structure. The mesh net simultaneously allows air circulation while its protruding portions apply pressure to specific points on the back, merging two previously separate functions into one unified component.
2Temperature
If the mesh net is spaced apart from the storage part, then ventilation is enabled, but the structure does not provide massaging effect on the wearer
Solution Approach 1:
The mesh net incorporates localized protruding portions at specific positions corresponding to acupoints on the wearer's back. These localized structural features provide targeted massaging effects while the overall mesh structure maintains ventilation functionality, resolving the contradiction through spatially differentiated design.
3Object-affected harmful factors
If a conventional ventilation plate is used, then sweating is prevented, but ventilation is not effectively improved and no health-promoting effect is achieved
Solution Approach 1:
The mesh net features protruding portions with curved surfaces that better conform to the contours of the wearer's back compared to flat ventilation plates. This curved geometry improves contact with the back surface, enhancing both ventilation efficiency and massaging effects on acupoints.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The backpack enhances ventilation and provides a health-promoting effect by maintaining airflow and applying targeted pressure to reduce fatigue and improve comfort during extended wear.
Implementation Method 1
a ball member (13) which is supported by the spring (12)
Implementation Method 2
a mesh net (10) which is attached to the frame (11) and arranged apart from the storage part (2)

AI summary
A backpack ensuring a ventilation and improving a health-promoting effect is provided. The backpack (1) includes; a storage part (2); a pair of shoulder belts (3) attached to the storage part (2); and a supporter (4) worn on a back of a wearer with supporting the storage part (2). The supporter (4) includes: a mesh net (10) having ventilation characteristic; an annular frame (11) provided along the storage part (2) in up-down and right-left directions; and a ball member (13) provided between the mesh net (10) and the storage part (2) and attached to the frame (11) via a spring (12). The ball member (13) is arranged to bias in a direction where the mesh net (10) is pushed by the spring (12) when the backpack (1) is worn on the back of the wearer with the shoulder belts (3).
