Electrical Treatment Device Asymmetric Marking for Limb Electrode Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical stimulation devices face challenges in accurately positioning electrode portions on both the left and right lower limbs, leading to increased manufacturing costs and reduced effectiveness when attempting to treat both limbs with a single device.
Innovation Solution
An electrical treatment device featuring a band-like member that can be wrapped around both lower limbs, with strategically positioned first and second mark portions guiding the electrode portions to specific target positions on each limb, ensuring appropriate contact and differing dermatome stimulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single electrical stimulation device is used for both left and right lower limbs, then manufacturing costs are reduced, but it becomes difficult to bring electrode portions into contact with appropriate locations on both limbs
Solution Approach 1:
The band-like member incorporates asymmetric mark portions (first mark portion and second mark portion) positioned at different locations and orientations. When wrapped around the right lower limb, the first mark portion aligns with a specific position to guide electrodes to target positions. When wrapped around the left lower limb, the second mark portion aligns with a specific position to guide electrodes to corresponding target positions. This asymmetric design enables a single device to achieve accurate electrode positioning on both limbs despite their mirror-image anatomy.
2Manufacturing precision
If separate electrical stimulation devices are manufactured for left and right lower limbs, then electrode positioning accuracy is improved, but manufacturing costs increase
Solution Approach 1:
The electrical stimulation device is designed with universal applicability to both left and right lower limbs through the band-like member with strategically positioned mark portions. The same device can be used on either limb by rotating or repositioning the band, with the first and second mark portions guiding electrode placement appropriately for each limb. This multi-functional design eliminates the need for separate left and right devices, reducing manufacturing costs while maintaining positioning accuracy.
3Adaptability or versatility
If the band-like member is wrapped around the lower portion of the torso, then it can treat the torso, but it cannot be effectively used for lower limb treatment
Solution Approach 1:
The band-like member is designed with flexible positioning capabilities, allowing it to be wrapped around different body parts including the torso and lower limbs. The mark portions are positioned and oriented to provide guidance references that adapt to different wrapping configurations. When wrapped around the lower limb, the band maintains appropriate tension and positioning to ensure electrodes contact the correct dermatomes, enabling dynamic adaptation to different treatment sites while maintaining positioning precision.
