Backpack Golf Practice Tool Using Visual Posture Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beginners in golf face difficulties in determining the correct posture for hitting the ball, particularly the forward tilt angle of the upper body and rotation angle during backswing, due to the complexity and size of existing golf practice tools, which are cumbersome and require specialized knowledge.
Innovation Solution
A backpack carrier type golf practice tool with a columnar box featuring adjustable striped line patterns on its surface, allowing golfers to adjust their upper body inclination and rotation, made of lightweight materials like foamed plastic or urethane foam, and an optional arm supporter with vertical striped patterns for arm alignment, enabling easy practice and posture correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a large and complex golf practice tool with a straight rod and tripod is used to define posture, then measurement precision of posture is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The large tripod structure is segmented into a compact columnar box that can be carried on the back. The posture reference function is segmented into visual patterns (striped line patterns and striped patterns) on the box surface, separating the measurement reference from the complex mechanical support structure.
Solution Approach 2:
Instead of using a physical straight rod to define posture, the invention uses visual copies of posture references in the form of striped patterns and line patterns printed on the box surface. These patterns serve as optical references that eliminate the need for physical alignment tools.
2Measurement precision
If a large golf practice tool with a straight rod is used to correct posture, then measurement precision is improved, but ease of operation deteriorates due to specialized knowledge required
Solution Approach 1:
The invention uses striped line patterns and striped patterns with distinct visual characteristics (colors and arrangements) to indicate different posture positions. Beginners can visually identify their posture by observing which patterns are visible or how they appear, eliminating the need for specialized knowledge about rod positioning.
Solution Approach 2:
The mechanical alignment system (physical straight rod requiring precise positioning) is replaced with an optical system using visual patterns on the box surface. This substitution allows beginners to self-correct posture through visual feedback without requiring mechanical expertise.
3Measurement precision
If a large golf practice tool is used to define upper body posture, then measurement precision is improved, but weight of moving object increases
Solution Approach 1:
The invention replaces heavy physical alignment tools with lightweight visual pattern references printed or applied on the box surface. The striped patterns and line patterns serve as massless optical references that provide posture guidance without adding significant weight.
Solution Approach 2:
The invention changes the reference from physical dimensions (length of straight rod, position in space) to visual parameters (patterns, colors, line arrangements) on the box surface. This parameter change allows posture measurement without requiring heavy mechanical structures.
4Measurement precision
If a complex tripod and straight rod system is used for golf practice, then measurement precision is improved, but ease of operation deteriorates due to troublesome carrying
Solution Approach 1:
The large tripod structure is segmented and reduced to a compact columnar box form factor that can be comfortably carried on the back like a backpack. This segmentation transforms an immobile or difficult-to-move structure into a portable device suitable for golf course use.
Solution Approach 2:
The columnar box serves multiple functions: it provides posture reference through its patterns, acts as a portable carrier on the back, and eliminates the need for separate tripod and rod components. This multi-functionality consolidates what would otherwise be multiple separate pieces of equipment into one portable unit.

AI summary
A golf practice tool is provided having a columnar box. The columnar box is provided with a shoulder belt and the columnar box is carried on the back of the golf player. The columnar box has a substantially flat upper surface. A plurality of striped line patterns or striped patterns substantially parallel to a side surface, which touches a back of a person and is called a back touch side surface, of the columnar box are drawn on the upper surface. The degree of inclination of the upper body of the golf player when playing golf can be adjusted by using the striped line patterns or the striped patterns. On side surfaces other than the back touch side surface of the columnar box, a plurality of vertical striped line patterns or vertical striped patterns are drawn substantially at right angles to the bottom surface of the columnar box. The degree of rotation of the upper body at a golf swing can be adjusted by using the vertical striped line patterns or the vertical striped patterns.
