Solution Overview

Problem

Conventional vehicle lid lock devices with emergency unlocking mechanisms have complex structures, high manufacturing costs, and poor operability due to multiple components, which can lead to operational errors and component loss during emergencies.

Innovation Solution

A vehicle lid lock device with a simplified structure featuring a handle member fixed to the vehicle interior via an integrally formed clip part, allowing tilting motion for easy operation, and a cable connecting the handle member to the lock pin, reducing the number of components and ensuring reliable operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the handle member is detachably disposed in a fitting hole in the vehicle body, then the emergency lid unlocking mechanism can be implemented, but the structure becomes complex and the number of components increases

Engineering Contradiction:
Improveemergency lid unlocking capabilityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The handle member is integrated with the vehicle body through a fitting protrusion and fitting hole structure, merging two previously separate components (handle member and vehicle body mounting structure) into a unified assembly. This eliminates the need for separate detachable connections while maintaining emergency unlocking functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The handle member serves multiple functions: it acts as both the emergency unlocking actuator and the mounting structure itself through its integrated fitting protrusion. The same component that users grip to unlock the lid also provides the structural connection to the vehicle body, eliminating the need for separate mounting hardware.

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

2Reliability

If the handle member is detachably disposed in a fitting hole in the vehicle body, then the emergency lid unlocking mechanism can be implemented, but manufacturing cost increases

Engineering Contradiction:
Improveemergency lid unlocking capabilityVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

By integrating the mounting function into the handle member itself, the number of separate parts is reduced. This consolidation decreases manufacturing complexity, assembly steps, and associated costs while maintaining the emergency unlocking capability.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If the handle member is disposed in a narrow, inconspicuous space inside the vehicle body, then the emergency lid unlocking mechanism can be implemented, but operability deteriorates

Engineering Contradiction:
Improveemergency lid unlocking capabilityVSAvoidoperability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The handle member is designed to extend outward from the vehicle body surface in a direction perpendicular to the mounting surface. This spatial extension brings the operational interface (grip portion) to an accessible location outside the narrow internal space, improving user reach and operability while maintaining the compact internal structure.

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

4Device complexity

If the handle member is fixed to the vehicle body, then the structure is simplified, but the handle member cannot be detached for maintenance or replacement

Engineering Contradiction:
Improvestructure simplicityVSAvoidmaintenance accessibility
Core Design Contradiction:
Device complexityVSEase of repair

Solution Approach 1:

The fitting protrusion is designed as a removable interference fit structure that can be extracted from the fitting hole. This allows the handle member to be detached from the vehicle body for maintenance or replacement while maintaining a simple integrated structure during normal operation. The extraction capability is built into the fundamental mounting design rather than requiring separate fastening mechanisms.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A vehicle lid lock device includes: a drive actuator; a lock pin movable between a first position where one end thereof is engaged with a part of a lid in a vehicle exterior panel to maintain the lid closed and a second position where the lock pin is disengaged from the part of the lid to allow the lid to open; a handle member to be gripped by a user; and a cable having one end coupled to another end of the lock pin and another end coupled to a part of the handle member and configured to retract the lock pin to disengage the lock pin from the part of the lid member when the user pulls the handle member. A clip part is formed integrally with the handle member. The handle member is tiltable with respect to a fixing surface of the vehicle interior structure.
