Back Protector Cable Tightening for Precise Abdominal Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing back protection equipment for sports like cycling lacks precise and durable adjustment mechanisms, leading to discomfort and frequent strap adjustments during high-intensity activities.
Innovation Solution
A back protection device with adjustable tightening devices featuring reels, cables, and clamping mechanisms on lateral straps, allowing for precise and quick adjustment of abdominal tightness, and optionally including thermal regulation layers for temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adhesive hook and loop fasteners are used on straps for adjustment, then the equipment can be easily adjusted, but the durability is poor and precise tightening adjustment is not allowed
Solution Approach 1:
The patent replaces the adhesive hook and loop fastening system with a mechanical reel-based cable tensioning system. The reel mechanism with cable and pulley provides durable, precise mechanical adjustment while maintaining ease of operation through rotational control of the reel handle.
Solution Approach 2:
The patent introduces a dynamic adjustment mechanism where the reel can be rotated to change cable length and tension in real-time. This allows continuous adjustment of strap tightness during activity, transforming the static fastening system into a dynamically adjustable one.
2Adaptability or versatility
If adhesive hook and loop fasteners are used on straps, then adjustment is possible, but precise tightening adjustment is not achieved
Solution Approach 1:
The reel-based mechanical system provides precise control over cable tension through incremental rotation of the reel. The cable winds and unwinds in controlled amounts, enabling fine-tuned adjustment of strap tightness that adhesive fasteners cannot achieve.
Solution Approach 2:
The patent changes the adjustment parameter from discrete adhesive fastener positions to continuous cable length variation through reel rotation. This allows precise control of tightening force and position, enabling adaptation to different anatomical positions and activity requirements.
3Stability of the object's composition
If the equipment is tightened around the abdomen with straps, then the protective equipment is secured in position, but frequent loosening and tightening is required during use
Solution Approach 1:
The reel mechanism enables dynamic adjustment of strap tension during activity without requiring complete loosening and re-tightening. Users can quickly rotate the reel to adjust tightness as needed, reducing the time and effort required for frequent adjustments during cycling or other sports activities.
4Ease of operation
If adhesive hook and loop fasteners are used, then straps can be adjusted, but additional wear on the fasteners occurs
Solution Approach 1:
The patent substitutes the adhesive hook and loop fasteners with a mechanical reel and cable system that distributes wear across durable metal or plastic components. The reel, cable, and pulley mechanism are designed for long-term repeated use, significantly extending the service life compared to adhesive fasteners that degrade with frequent adjustment cycles.
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
Provides improved comfort and support during prolonged sports activities by enabling fine adjustment of abdominal tightness and thermal regulation, reducing the need for frequent strap adjustments and enhancing user protection.
Implementation Method 1
a reel attached to the first side strap, a handling and adjustment disc mounted on the reel, a cable arranged on the reel in such a way as to be wound and unwound by the action of the disc
Implementation Method 2
it is known to use adhesive hook and loop fasteners mounted on the straps
Implementation Method 3
An internal surface of the dorsal part and, where applicable, of the ventral part, may include a thermal regulation layer
