Removable Backpack Massage Structure for Stable Body Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backpacks with massage functions have poor fit and massage effectiveness due to the adjustment of shoulder straps affecting the position of the massage head, leading to discomfort and reduced efficacy.
Innovation Solution
An adjustable massage structure with a back panel divided into upper and lower parts, using second webbing on shoulder straps for precise positioning of the massage head, and a second adjustment part to maintain close fit without shaking, along with a removable massage system integrated via detachable accessories for enhanced comfort and efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the shoulder straps are adjusted to change the position of the massage head, then the massage position can be modified, but the massage head loses close contact with the shoulder and back, reducing massage effectiveness
Solution Approach 1:
The back panel is divided into upper and lower parts with independent adjustment mechanisms. The upper part contains the massage head while the lower part provides structural support. This segmentation allows the upper part to be adjusted independently via the second webbing without compromising the stability provided by the lower part, thus maintaining both adjustability and contact stability.
Solution Approach 2:
The second webbing acts as an intermediary adjustment mechanism between the shoulder straps and the massage head position. It provides a dedicated adjustment path that allows position modification without directly moving the shoulder straps, thereby maintaining the massage head's close contact with the body while enabling position changes.
2Device complexity
If the massage system is permanently integrated into the backpack, then the structure is simplified, but the massage system cannot be removed when not needed, reducing versatility
Solution Approach 1:
The connection between the massage system and backpack is made dynamic rather than static. Detachable accessories enable the massage system to be easily attached and detached, allowing the structure to adapt between a simple integrated state and a versatile configurable state based on user needs.
Solution Approach 2:
The backpack is designed with universal attachment points and detachable accessories that allow the massage system to be optionally integrated. This multi-functionality enables the same backpack structure to serve both as a simple carrier and as an enhanced massage device depending on whether the massage system is attached.
3Ease of operation
If the second webbing adjustment component is positioned away from the vertical surface, then adjustment is easier, but the backpack creates left and right shaking and gaps between the back panel and shoulder
Solution Approach 1:
The second adjustment part is positioned asymmetrically close to the vertical surface of the back panel, creating a compact adjustment mechanism that maintains structural stability. This asymmetric placement allows the adjustment component to be accessible while keeping the webbing path short and direct, preventing shaking and gaps.
4Measurement precision
If the massage head is firmly fixed in the shoulder strap, then positioning is precise, but installation and removal of the massage head becomes difficult
Solution Approach 1:
The massage head is held in the shoulder strap through a dynamic elastic storage space rather than rigid fixation. The elastic properties provide firm holding during use for precise positioning, while allowing easy insertion and removal when needed, thus balancing positioning accuracy with installation ease.

AI summary
A biomechanically adaptive wearable system includes a wearable body configured to be worn on a user's torso and to bear a load. A removable massage system is detachably integrated with the wearable body. The removable massage system includes at least at least one massage head structurally integrated with the wearable body via at least one pair of a detachable accessory. The at least one massage head includes a massage actuator; and a pressure sensor configured to detect, in real-time, pressure variations originating from the load and the user's torso. A control system includes a microcontroller unit programmed to receive and analyze the signals from the pressure sensor to determine a required adjustment to massage intensity; and automatically generate and send a control command to the massage actuator to operate according to the determined required adjustment.
