Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication terminals, such as mobile phones, often fail to promptly alert users in noisy environments due to reliance on visual, auditory, or vibrational cues, leading to missed important information.
Innovation Solution
An information prompting bracelet featuring a flexible substrate with control portions and arched pressure levers that move to squeeze an elastic deformation portion, creating a noticeable pressure sensation on the wearer's arm when alert information is received, allowing for timely notification regardless of environmental noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual, sound or vibration effects are used for information prompting in existing terminals, then the prompting method is simple and straightforward, but the user may not receive the prompting in time in noisy environments or when the terminal is not close to the user's body
Solution Approach 1:
The bracelet is divided into multiple independent control portions (first, second, third, fourth control portions) that can be independently activated. Each control portion contains its own control unit and pressure lever, allowing selective activation of different tactile feedback locations on the wrist based on the type of information being conveyed, thereby improving prompting reliability through distributed sensing elements.
Solution Approach 2:
The patent replaces traditional visual, auditory, and vibrational prompting mechanisms with a mechanical tactile feedback system. Pressure levers mechanically deform the elastic deformation portion to create direct contact pressure sensations on the user's wrist, substituting electronic/vibrational mechanisms with pure mechanical force transmission for more reliable information delivery.
2Reliability
If multiple control portions and pressure levers are added to create tactile feedback, then the information prompting reliability improves, but the device complexity increases
Solution Approach 1:
Multiple control units and pressure levers are merged into a unified elastic deformation portion that spans across different control portions. This single integrated elastic component replaces what would otherwise require multiple separate mechanical actuators, reducing overall device complexity while maintaining the ability to provide differentiated tactile feedback at multiple locations.
Solution Approach 2:
The elastic deformation portion serves multiple functions simultaneously: it acts as a structural support element, a force transmission medium, and the actual tactile feedback interface. This multi-functional design eliminates the need for separate components for each function, thereby reducing device complexity while achieving reliable multi-point tactile feedback.
3Reliability
If the elastic deformation portion is squeezed by pressure levers to create pressure sensation, then the user awareness of prompts improves, but the force required to activate the mechanism increases
Solution Approach 1:
The pressure levers are designed with arched or curved structures rather than straight rigid beams. This curvature allows the levers to flex and deform more easily under applied force, reducing the activation force required while still transmitting sufficient mechanical force to create noticeable pressure sensations through the elastic deformation portion.
Solution Approach 2:
The elastic deformation portion's material properties and geometric parameters are optimized to achieve the right balance between sensitivity and force transmission. By adjusting the elasticity modulus, thickness, and length of the elastic portion, the system achieves low activation force while maintaining reliable prompt detection accuracy through adequate pressure sensation.

Function Achieved in This Case
Ensures timely notification of alert information through a tactile sensation, even in noisy environments, enhancing user awareness of important prompts without the need for visual or auditory attention.
Implementation Method 1
the elastic deformation portion can be squeezed towards the middle region by the pressure levers, so that the distance between the inner surface of the elastic deformation portion at the middle region and the inside of the flexible substrate after squeezing will be larger than the distance between the inner surfaces of the pressure levers and the inside of the flexible substrate when in initial position

AI summary
The present disclosure relates to an information prompting bracelet and an information prompting system. The information prompting bracelet includes: a flexible substrate, a connecting portion, control portions, pressure levers and an elastic deformation portion. When the control portions receive promoting information, they will control the pressure levers to move towards the side facing the flexible substrate. With the movement of the pressure levers, the elastic deformation portion will be squeezed towards the middle region, so that the distance between the inner surface of the elastic deformation portion at the middle region and the inside of the flexible substrate after squeezing will be larger than the distance between the inner surfaces of the pressure levers and the inside of the flexible substrate when in an initial position. In this way, this will bring the wearer a sense of pressure to notify the wearer that there is a prompting signal needing to be received.
