Solution Overview

Problem

Conventional boxing devices are unsafe for ordinary people, especially children, and existing toys lack the realism and physical exercise benefits of a traditional boxing match, with many requiring manual trigger activation or being unsuitable for interactive play between two participants.

Innovation Solution

A boxing device featuring an extensible joint with multiple extension elements that auto-retracts after use, allowing for propulsive force to extend the buffer towards a target via arm movement, enabling realistic punching motions without harm and accommodating various skill levels and distances.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional boxing gloves are used, then boxing matches can be performed, but participants risk injury and harm

Engineering Contradiction:
ImprovesafetyVSAvoidinjury risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies prior cushioning by incorporating a buffer between the extensible joint and the target that is configured to absorb impact energy. The buffer prevents direct contact between the punching mechanism and the target, cushioning the impact beforehand to eliminate injury risk while preserving the boxing match functionality.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

2Ease of operation

If existing boxing toys with elastic cords are used, then amusement is provided, but the toys cannot be used for real boxing matches due to inability to control punch direction and slow reset

Engineering Contradiction:
Improvepunch controlVSAvoidmatch speed
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent replaces the elastic cord mechanical system with an extensible joint mechanism that uses a spring-loaded arm. This substitution provides controlled extension in the punch direction through the spring mechanism while enabling rapid automatic retraction, thereby improving both punch control and match speed compared to elastic cord toys.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The extensible joint incorporates a spring mechanism that dynamically extends and retracts the punching arm. The spring provides controlled extension during the punch and automatic rapid retraction afterward, creating a dynamic system that adapts to the boxing match rhythm and enables fast successive punches.

Inventive Principle:
Principle #15Dynamics

3Object-affected harmful factors

If virtual boxing matches are used, then harm is eliminated, but expensive equipment and screens are required reducing accessibility

Engineering Contradiction:
Improveharm eliminationVSAvoidequipment cost
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent creates a physical copy of the boxing experience that eliminates harm. Instead of using expensive virtual reality equipment and screens, it provides a tangible boxing device with a soft buffer that replicates the punching motion and experience physically, making it accessible without costly technology.

Inventive Principle:
Principle #26Copying

4Ease of operation

If boxing devices require manual trigger activation, then mechanism control is achieved, but realistic punching motions and physical exercise are reduced

Engineering Contradiction:
Improvemechanism controlVSAvoidphysical exercise
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The extensible joint with spring mechanism is designed to be activated by the natural punching motion itself. The user's arm movement compresses the spring and triggers the extension automatically, eliminating the need for separate manual trigger activation. This self-service design maintains realistic punching motions and preserves physical exercise benefits.

Inventive Principle:
Principle #25Self-service

AI summary

A boxing device (1,100,200a,200b,300,400) serves for performing a harmless boxing match. The boxing device (1,100,200a,200b,300,400) comprising a base (2,5,53,87), a buffer (3,6,54) configured to hit a target (A,B,75) without injuring said target (A,B,75), and an extensible joint (4,7,54) that connects the base (2,5,53,7) and the buffer (3,6,54) to move said buffer between a retracted position and one or more extended positions. The extensible joint (4,7,52,82) is an element assembly of at least two extension elements (8,9,55,56,80a,80b), the extensible joint is configured to move the buffer (3,6,54) into the one or more extended positions by virtue of the propulsive force transferred to the extensible joint (4,7,52,82) by a punch done by a hand of a boxer (A,B) holding the boxing device (1,100,200a,200b,300,400), and auto- retract after the punch has been performed. The harmless boxing match of the invention is an enjoyable and beguiling exercise, which furthermore impart good and healthy motion to the participants.
