Integrated Sighting Line for Real-Time Parallax Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sighting aids for sports like snooker and golf are ineffective in real-time game situations due to parallax error caused by eye dominance, stance, technique, and coaching issues, which cannot be diagnosed or corrected by coaches.
Innovation Solution
A sighting aid integrated into sports equipment, such as a snooker cue or golf club head, featuring a longitudinal sighting line intercepted by a step, allowing users to visually correct parallax error during gameplay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a stand-alone sighting aid is used in training environments, then users can perceive and practice correcting parallax error, but the device becomes useless outside training sessions and cannot provide real-time correction during actual gameplay
Solution Approach 1:
The patent combines the sighting aid functionality directly with the sports equipment (cue or club head) by integrating a sighting line into the equipment's structure. This merging allows the device to serve dual purposes: as a training tool for perceiving parallax error and as a real-time aid during actual gameplay, eliminating the limitation of standalone devices that are only useful in training environments
2Ease of operation
If coaches provide guidance on parallax error correction, then users receive external advice, but coaches cannot effectively diagnose the problem since they cannot see through the player's eyes
Solution Approach 1:
The sighting line integrated into the equipment enables users to self-diagnose and self-correct parallax error by directly observing the misalignment through their own visual perspective. The device provides immediate visual feedback that allows players to identify and correct their own stance and alignment issues without relying on coaches to interpret their posture or guess at visual errors
3Measurement precision
If traditional sighting methods are used without visual feedback mechanisms, then equipment remains simple, but users cannot accurately perceive or correct parallax error in real-time
Solution Approach 1:
The patent uses visual contrast and color differentiation in the sighting line design to enhance visibility and provide clear visual feedback. By making the sighting line distinctly visible against the equipment background, the design enables accurate perception of alignment and parallax error without requiring complex electronic or mechanical systems, achieving high measurement precision through simple optical contrast
