Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hockey training nets lack the ability to dynamically adjust target spaces to simulate various shooting scenarios, limiting the effectiveness of skill development for hockey players.
Innovation Solution
An apparatus with movable blockers that adjust the goal opening to define a target space, allowing for variable size and shape through independent movement of panels, controlled by a guiding mechanism and motor system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If stationary targets are used in training nets, then the structure is simple and stable, but the adaptability for different shooting scenarios is limited
Solution Approach 1:
The patent applies the dynamics principle by transforming stationary targets into movable blockers that can be dynamically repositioned within the goal. The blockers are mounted on sliding mechanisms allowing them to move horizontally and vertically, enabling the training system to adapt to various shooting scenarios while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent segments the target structure into multiple independent blockers rather than using a single fixed target. Each blocker can be independently positioned and adjusted, providing versatility for different training scenarios while keeping each individual blocker simple in design.
2Adaptability or versatility
If fixed targets are used, then the device is easy to manufacture and operate, but the ability to simulate various shooting angles and locations is reduced
Solution Approach 1:
The blockers are designed with sliding mechanisms that allow easy repositioning along horizontal and vertical tracks. This dynamic capability enables trainers to simulate various shooting angles and locations by simply moving the blockers to different positions, maintaining ease of operation while significantly improving adaptability.
Solution Approach 2:
The movable blockers serve multiple functions: they can be positioned to create different target sizes, simulate various goalie positions, and represent different vulnerable areas on the goal. This multi-functionality allows a single apparatus to replace multiple fixed targets, enhancing versatility without complicating operation.
3Productivity
If movable blockers are introduced to create variable target spaces, then training effectiveness is improved, but the device complexity increases
Solution Approach 1:
The patent introduces movable blockers with sliding mechanisms that add dynamic capabilities to the training apparatus. The blockers can be independently positioned along horizontal and vertical axes, creating variable target spaces that enhance training effectiveness. The complexity is managed by using straightforward mechanical sliding mechanisms rather than complex automated systems.
Solution Approach 2:
By dividing the target area into multiple independent movable blockers, the system achieves high training effectiveness through varied target configurations. Each blocker remains a simple, manageable component, allowing the overall system to be effective without becoming overly complex.

AI summary
An apparatus for use in conjunction with a goal having a frame defining an opening is provided. The apparatus includes at least two movable blockers adapted to selectively define a target space within the opening. First and second blockers are perpendicular and mounted on portions of the frame. The first blocker has a pair of opposed horizontal first free edges defining a first free space between the first free edges and movable in a vertical direction to increase or decrease the first free space therebetween. The second blocker has a pair of opposed vertical second free edges defining a second free space between the second free edges and movable in a horizontal direction to increase or decrease the second free space therebetween. The first free space and the second free space define the target space.
