Exercise Apparatus Elastic Band Ball Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bed exercise equipment for patients, such as rubber bands and balls, are inconvenient due to ease of loss, difficulty in handling for physically disabled patients, and frequent tearing from concentrated resistance points.
Innovation Solution
An exercise apparatus comprising an elastic band with hanging and opening portions, and a pair of balls connected to the elastic band, allowing for adjustable tension and secure fixation at various positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a rubber band is used for bed exercise, then resistance can be provided for exercise, but the rubber band may easily tear because resistance is concentrated in a portion where the rubber band is tied
Solution Approach 1:
The rubber band is divided into multiple segments by adding reinforcement members (such as fabric strips or plastic coatings) at critical stress points. These reinforcement members distribute the concentrated resistance forces across multiple layers and materials, preventing the rubber band from tearing at single points while maintaining the necessary resistance for exercise.
2Force
If a rubber band is used for bed exercise, then resistance can be provided for exercise, but the rubber band needs to be newly tied whenever the rubber band is used, and it is inconvenient as the rubber band needs to be untied again after use
Solution Approach 1:
The exercise apparatus is pre-assembled with the rubber band attached to the bed frame at predetermined positions during manufacturing. This preliminary action eliminates the need for patients to tie and untie the rubber band during each use, significantly improving convenience while maintaining the resistance function.
Solution Approach 2:
Fastening mechanisms such as Velcro straps, buckles, or magnetic attachments are introduced as intermediaries between the rubber band and the bed frame. These intermediaries simplify the connection process, allowing for quick attachment and detachment without requiring tying knots, thus improving ease of operation.
3Adaptability or versatility
If a rubber band is used for bed exercise, then resistance can be provided for exercise, but a rubber band needs to be fixed at various positions so that patients may exercise with various actions, but such inconvenience restricts use of the rubber band
Solution Approach 1:
The apparatus incorporates adjustable components such as movable clips, sliding fasteners, or repositionable anchors that allow the rubber band to be easily moved to different positions on the bed frame. This dynamic adjustability enables patients to change exercise positions and actions without the inconvenience of re-tying the rubber band, thus maintaining both versatility and ease of operation.
Solution Approach 2:
The fastening system is designed to work at multiple locations and orientations on the bed frame, allowing a single apparatus to support various exercise actions and positions. This universal design enables the same rubber band to be used for different exercises by simply adjusting its attachment points, combining adaptability with convenience.
