Solution Overview

Problem

Existing sports bottom wear fails to effectively suppress muscle vibration and maintain good wearing comfort during exercise.

Innovation Solution

The sports bottom wear features a stretchable main cloth with strategically positioned strongly tightened parts A and B, covering areas prone to muscle vibration, and uses a hot-melt adhesive for bonding to minimize sewing lines, ensuring tight body contact and comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If strongly tightened parts are added to suppress muscle vibration, then exercise performance is improved, but wearing comfort deteriorates

Engineering Contradiction:
Improveexercise performanceVSAvoidwearing comfort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies different tightness levels to different regions of the bottom wear. Strongly tightened parts are strategically positioned only in muscle-prone areas (thighs, calves, buttocks) while other regions maintain normal elasticity. This localized differentiation suppresses muscle vibration where needed without compromising overall wearing comfort.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The bottom wear is divided into multiple functional zones with different compression characteristics. The strongly tightened parts are segmented into specific locations (front thigh, medial compartment, calf) rather than applying uniform compression throughout, allowing targeted muscle support while maintaining comfort in non-critical areas.

Inventive Principle:
Principle #1Segmentation

2Reliability

If strongly tightened parts are disposed to cover muscle areas prone to vibration, then muscle vibration is suppressed, but the structure becomes more complex

Engineering Contradiction:
Improvemuscle vibration suppressionVSAvoidstructure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple strongly tightened parts are merged into a single integrated bottom wear garment rather than using separate devices. The different tightened regions (front thigh part, medial compartment part) are combined in one piece of clothing, simplifying the overall structure while maintaining multiple functional zones for vibration suppression.

Inventive Principle:
Principle #5Merging (Combining)

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

The design effectively suppresses muscle vibration and maintains comfort by minimizing muscle shaking and interference with athletic movements while providing suitable support for posture and movement.

AI summary

Sports bottom wear (1) that includes a stretchable main cloth (2a, 2b, and 2c) that covers an area spanning from the waist to at least above the knees and is worn substantially in tight contact with the body includes: a strongly tightened part A (4a, 4b) that is disposed in a region of a front portion of the main cloth (2a, 2b), the region lying below a line extending in a lateral direction from a crotch portion of the front portion and above a knee; and a strongly tightened part B (5a, 5b) that is disposed in a region along a medial compartment of a thigh. The strongly tightened parts A and B may be constituted by a cloth piece of the main cloth or a cloth piece different from the main cloth, the cloth piece being bonded to a back face or a front face of the main cloth by means of an adhesive. Accordingly, it is possible to provide sports bottom wear that can improve exercise performance by suppressing muscle vibration and maintain good wearing comfort.
