Solution Overview
Problem
Existing knee pad brackets fail to provide comfortable wear, effective shock absorption, and massage functions while maintaining stability and adjustability for different body shapes, often causing hot feelings and inadequate relief for knee soreness.
Innovation Solution
A knee pad bracket design featuring a multi-layered frame structure with pivot axes, elastic elements, and a vibration module, allowing for adjustable tightness and massage, while incorporating a cushion for comfort and air permeability, and utilizing a control module for vibration control and safety features like inclining sensing and distance detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a one-piece sleeve design is used to wrap around the knee, then the knee is protected and correct posture is maintained, but the user experiences hot feeling and discomfort during prolonged wear
Solution Approach 1:
The knee pad bracket is divided into multiple segments including a first frame with first arc portion, second frame with second arc portion, third frame with third arc portion, and fourth frame with fourth arc portion. These segments are connected through pivot axes, allowing the structure to be divided into manageable parts that can move independently while maintaining overall knee protection functionality.
Solution Approach 2:
The patent incorporates pivot axes that enable dynamic movement between the frame segments, allowing the knee pad to adapt to knee motion. The elastic elements provide dynamic tension and compression responses. This dynamic structure replaces the static one-piece sleeve design, maintaining protection while improving comfort during prolonged wear through adaptive movement.
2Adaptability or versatility
If Velcro is used to adjust tightness for different body sizes, then the knee pad can be customized to fit different users, but the flexibility is reduced and shock absorption effect is compromised
Solution Approach 1:
The patent replaces static Velcro fastening with dynamic elastic elements that automatically adjust to different body sizes while maintaining shock absorption capability. The elastic elements can stretch and compress dynamically, providing both size adaptability and mechanical shock absorption that Velcro cannot achieve.
Solution Approach 2:
The elastic elements allow the knee pad structure to change its physical parameters (tension, compression, flexibility) in response to different body sizes and applied forces. This parameter change capability enables both adaptability to different users and maintenance of shock absorption properties simultaneously.
3Reliability
If a mechanical bone type structure is used for strong resistance fixation, then the fixation strength is improved, but the device becomes complicated in process and installation, prone to slipping, and expensive
Solution Approach 1:
The complex mechanical bone type structure is segmented into simpler frame components (first, second, third, and fourth frames) connected by pivot axes. This segmentation reduces overall complexity while maintaining fixation strength through the distributed structure that works together to provide stable knee support.
Solution Approach 2:
The patent uses elastic elements as flexible components that provide the necessary resistance and fixation without requiring complex rigid mechanical structures. These flexible elements simplify the overall device design while maintaining the required fixation strength through elastic deformation rather than complex mechanical interlocking.
4Reliability
If prior knee pad brackets focus only on fixation, then the knee is stabilized, but the sore feeling from the knee cannot be relieved
Solution Approach 1:
The knee pad bracket is designed to perform multiple functions simultaneously: it provides fixation through the frame structure and pivot axes, while the elastic elements provide shock absorption and massage effects to relieve knee soreness. This multi-functionality allows the device to maintain knee stability while also addressing comfort and pain relief needs.
Solution Approach 2:
The elastic elements in the knee pad bracket can generate mechanical vibration and massage effects when the knee moves, providing therapeutic benefits that relieve soreness. This vibration function is integrated into the fixation structure, allowing simultaneous stabilization and pain relief without requiring separate devices.
