Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple wrenches are connected by damping in a single direction, then the wrenches can be stored and blocked, but the unlocking operation becomes cumbersome and laborious

Engineering Contradiction:
Improveblocking capabilityVSAvoidunlocking operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent transforms the static single-direction blocking mechanism into a dynamic multi-directional blocking system. The engagement member can block tool members in multiple directions (at least two different directions), and the blocking engagement can be released and re-engaged easily through the unlocking assembly, making the blocking adaptive and flexible rather than fixed and cumbersome

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The unlocking assembly includes a reset member that automatically returns the engagement member to its blocking position after unlocking. This self-resetting mechanism eliminates the need for manual re-positioning of the engagement member, making the unlocking operation simpler and more efficient while maintaining reliable blocking capability

Inventive Principle:
Principle #25Self-service

2Device complexity

If a single-direction blocking mechanism is used, then the structure is simple, but the versatility of blocking different tool members is limited

Engineering Contradiction:
Improveblocking mechanism structureVSAvoidblocking directions
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The engagement member is designed with multi-directional blocking capability, allowing it to block different tool members in at least two different directions. This universal blocking mechanism can accommodate various tool members (wrenches, screwdrivers, etc.) regardless of their orientation, enhancing the adaptability of the tool kit without requiring separate blocking mechanisms for each direction

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The blocking mechanism is segmented into multiple independent blocking positions or engagement points. The engagement member can engage with tool members at different locations and orientations, providing segmented blocking coverage that maintains structural simplicity while achieving multi-directional versatility

Inventive Principle:
Principle #1Segmentation

AI summary

The present disclosure provides a tool kit including: a first holding member, a second holding member, a tool assembly, and an unlocking assembly. The second holding member is disposed in parallel with the first holding member, and a support cylinder member is connected therebetween to form an accommodation space. The tool assembly includes at least one tool member rotatably accommodated in the accommodation space. An end of the tool member is provided with a rotational connection part, and the rotational connection part is rotatably sleeved on the support cylinder member through a sleeve hole defined in the rotational connection part. The inner wall of the sleeve hole is concavely defined with an engagement groove. The unlocking assembly is movably mounted in a mounting hole of the support cylinder member. The unlocking assembly has a locked state and an unlocked state.
