Solution Overview

Problem

Existing outdoor portable goals are difficult to fold and unfold efficiently, occupying a large area and being inconvenient to carry, with the goal frame often unstable in a folded state due to resilience recovery forces.

Innovation Solution

The goal frame incorporates connecting rods and movable corner joints, allowing the frame to be folded and unfolded from different directions. Each movable corner joint consists of a first housing and a second housing connected to each other, with the first housing rotatable within a predetermined angle range, enabling the goal frame to switch between unfolded and folded states.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the goal frame is made with high toughness material to ensure strength, then the strength is improved, but the frame generates resilience recovery force that makes it difficult to stabilize in folded state

Engineering Contradiction:
ImprovestrengthVSAvoidstability in folded state
Core Design Contradiction:
StrengthVSStability of the object's composition

Solution Approach 1:

The patent extracts the harmful resilience recovery force by introducing a damping component that absorbs and dissipates the elastic energy generated by the tough frame material, preventing the frame from automatically unfolding while maintaining structural strength

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a damping component as an intermediary element between the frame members, which mediates the interaction by absorbing the resilience recovery force and converting it into heat energy, thereby stabilizing the folded state without compromising the frame's strength

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the goal frame is folded in a single direction to simplify structure, then the device complexity is reduced, but the occupied area remains large and portability is poor

Engineering Contradiction:
Improvestructure complexityVSAvoidoccupied area
Core Design Contradiction:
Device complexityVSArea of stationary object

Solution Approach 1:

The patent transitions from single-direction folding to multi-directional folding by introducing movable corner joints that enable rotation along multiple axes, allowing the frame to collapse into a compact three-dimensional configuration that minimizes occupied area while maintaining structural integrity

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent segments the frame into multiple movable sections connected by corner joints, allowing each section to be independently folded and repositioned, which enables compact multi-directional folding while keeping the overall structure relatively simple

Inventive Principle:
Principle #1Segmentation

3Device complexity

If manual operation is used to fold and store the goal to reduce device complexity, then the device complexity is reduced, but the ease of operation deteriorates and user experience is reduced

Engineering Contradiction:
Improvedevice complexityVSAvoidease of folding and storing
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent implements self-service functionality by incorporating a damping component that automatically stabilizes the frame in the folded state without requiring manual intervention, allowing the frame to maintain its folded configuration passively while improving ease of operation and storage

Inventive Principle:
Principle #25Self-service

Applied Scientific Principles
