Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floorball training devices are cumbersome to assemble, expensive, and components like threaded rods and elastic strings interfere with proper ball passing, disrupting training efficiency.
Innovation Solution
A floorball ball passer design featuring a first and second support with through holes, a hollow spacing tube fixed between them using screw bosses, and strings extending through these holes, with grooves to conceal the strings and protect them from mechanical damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded rods and connection elements are used to assemble the training device, then the device can be assembled with proper structural integrity, but the assembly requires a lot of labor work and takes time
Solution Approach 1:
The patent merges multiple separate components (threaded rods, connection elements, supports) into an integrated extruded profile structure. The single extruded profile combines the functions of supports, spacing elements, and attachment points into one unified component, eliminating the need for multiple separate parts and reducing assembly complexity while maintaining structural integrity.
Solution Approach 2:
The extruded profile is pre-manufactured with integrated features (slots, holes, spacing) already incorporated during the extrusion process. This preliminary formation of attachment points and structural features eliminates the need for on-site assembly of multiple components, significantly reducing assembly time while ensuring proper structural integrity.
2Strength
If threaded rods are used in the device structure, then proper structural support is achieved, but the threaded rods disturb proper use of the training device by interfering with ball passing
Solution Approach 1:
The patent extracts the interfering threaded rods from the device structure and replaces them with an extruded profile design that provides structural support through its geometry and material properties rather than through threaded fasteners. This removal of protruding threaded elements eliminates their interference with ball passing while maintaining necessary structural strength.
Solution Approach 2:
The extruded profile is designed with varying local qualities - different sections have different thicknesses, slots, and openings optimized for their specific functions. The profile provides structural support where needed while creating open spaces and channels that allow balls to pass freely without interference, achieving both strength and ease of operation through spatially varying properties.
3Adaptability or versatility
If multiple separate components are used to create the support structure, then the device can be assembled with proper flexibility, but the device becomes expensive and complex to assemble
Solution Approach 1:
The patent combines multiple separate support components into a single extruded profile that performs all structural functions. This unified component eliminates the complexity of assembling multiple parts while maintaining adaptability through integrated slots and attachment points that allow for flexible configuration and adjustment of training elements.
4Ease of operation
If elastic strings are positioned externally in the device, then the ball can bounce off the strings for training, but the strings may touch together with passed ball the threaded rods disturbing proper passing back from the device
Solution Approach 1:
The extruded profile acts as an intermediary structure that holds and positions the elastic strings. The profile's integrated design creates proper spacing and alignment between strings, preventing them from contacting threaded rods or interfering with ball passing, while still allowing balls to bounce off the strings effectively for training purposes.

AI summary
The present invention relates to floorball training devices to improve users stick-handling and ball passing abilities. The floorball ball passer (1) comprises two supports (2;22) and one hollow spacing tube (10) therebetween. The passer (1) comprises two sets of strings (20;21), where each set of strings (20;21) is extended between two supports (2;22) forming elastic string wall for bouncing off a ball. Each support (2;22) on its side wall (7) has a central region (23), at which the hollow spacing tube (10) is fixed to said support (2;22). Moreover the central region (23) of the support (2;22) comprises a pocket (24), in which one end of the hollow spacing tube (10) can be inserted, and wherein the central region (23) of the support (2;22) comprises a rim (25) extending around the pocket (24) enabling easy installation and subsequent holding of the hollow spacing tube (10) at the support (2;22).
