Solution Overview
Problem
Existing finger and hand exercisers fail to provide both adjustable tension for compression and extension exercises in a single unit, limiting their versatility and user adaptation.
Innovation Solution
A multi-functional finger exercise device with a central housing featuring a compression mechanism and an extension mechanism, both with adjustable tension, utilizing a threaded rod, tension adjustment nut, reciprocating plunger, and elastic line to allow for customizable resistance levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single unit finger exerciser is used, then device simplicity is improved, but tension adjustability for both compression and extension exercises deteriorates
Solution Approach 1:
The device integrates both compression and extension exercise mechanisms into a single unit, allowing it to perform multiple functions. The housing contains both a compression mechanism with plunger and spring, and an extension mechanism with elastic band, enabling users to perform both types of exercises with one device rather than requiring separate devices.
Solution Approach 2:
The device incorporates adjustable tension mechanisms for both compression and extension exercises. The compression mechanism allows tension adjustment by replacing springs with different spring rates, and the extension mechanism allows tension adjustment by changing elastic bands or modifying their configuration, enabling the device to adapt to different user needs and exercise requirements.
2Ease of manufacture
If fixed tension springs are used, then manufacturing simplicity is improved, but user adaptability deteriorates
Solution Approach 1:
The device allows users to change the physical parameters of the exercise resistance by selecting different springs with varying spring rates for compression exercises and different elastic bands for extension exercises. This enables users to adjust the tension parameter to match their individual strength levels and exercise progress, transforming a fixed-parameter device into a variable-parameter system.
3Adaptability or versatility
If separate compression and extension devices are used, then tension adjustability is improved, but device complexity deteriorates
Solution Approach 1:
The patent combines separate compression and extension exercise devices into a single integrated unit. The housing accommodates both a compression mechanism (with plunger, spring, and adjustment features) and an extension mechanism (with elastic band and anchoring points), allowing users to perform both types of exercises with one device rather than requiring two separate devices.
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
Enables users to perform a range of exercises with adjustable resistance, accommodating individual finger and hand variations, enhancing exercise effectiveness and user experience.
Implementation Method 1
a compression mechanism including a reciprocating plunger with a portion exposed from a first end of the housing, a compression adjuster axially fixed to the rod and a bias member positioned axially between the compression adjuster and the exposed portion plunger biases the plunger away from the housing
Implementation Method 2
an extension mechanism including an elastic line extending from a first end to a second end. The first end is fixed to the rod and the second end is fixed to an anchor member that is exposed on the second end of the housing
Data Source
AI summary
A multi-functional finger exercise device includes mechanisms for both compression exercises and extension exercises. The compression exercises are provided by a plunger biased away from a central housing. The extension exercises are provided by an elastic member with an anchor exposed from the housing. The tension provided by each of the compression mechanism and extension mechanism is adjustable.
