Trunk Handle Fixing Member as Locking Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trunks do not effectively utilize the fixing member for the handle, leading to unnecessary components and increased assembly steps, and lack enhanced security and functionality for vehicle use.
Innovation Solution
The fixing member for the handle is integrated into the trunk body or lid to serve as a guide for the locking mechanism, allowing for smoother sliding and enhanced security, with configurations such as multiple fixing members, slots, and a partition member to improve locking strength and prevent external manipulation, while also enabling secure mounting to a saddle-type vehicle with a single key operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate guide body is provided for the locking mechanism, then the locking mechanism can function properly, but the number of component parts increases
Solution Approach 1:
The patent merges the guide body function with the existing fixing member for the handle. The fixing member is designed to serve dual purposes: securing the handle to the trunk body and guiding the movement of the movable locking piece. This eliminates the need for a separate guide body, reducing component parts while maintaining proper locking mechanism function.
Solution Approach 2:
The fixing member is given multiple functions: it acts as both a handle mounting component and a guide body for the locking mechanism. By making the fixing member universal, the patent reduces the total number of components needed in the trunk assembly.
2Strength
If multiple fixing members are provided for the handle, then the handle fixation strength increases, but the number of component parts increases
Solution Approach 1:
The patent combines multiple fixing members into the handle assembly structure. Instead of adding separate fixing members as additional components, the design integrates them as part of the handle's mounting structure, thereby increasing fixation strength without proportionally increasing component count.
Solution Approach 2:
The fixing members are strategically positioned at multiple locations on the handle assembly to distribute mechanical loads. This segmentation of the fixation function across multiple integrated points enhances overall strength while maintaining a compact component structure.
3Ease of operation
If the fixing member is disposed outside the trunk body, then the locking mechanism is accessible, but the locking mechanism can be externally worked and security is reduced
Solution Approach 1:
The patent nests the locking mechanism components within the trunk body structure. The movable locking piece and fixing members are positioned inside the trunk body, with the locking action occurring internally. This nested arrangement prevents external manipulation while maintaining functional accessibility through the lid mechanism.
Solution Approach 2:
Instead of making the locking mechanism externally accessible for operation, the patent inverts the approach by placing the critical locking components inside the trunk body. The operation is achieved through the lid's movement which internally actuates the locking pieces, reversing the conventional external-accessible design.
4Device complexity
If a single fixing member guides the movable locking piece, then the structure is simple, but the sliding operation is rough and strength is reduced
Solution Approach 1:
The patent segments the guiding function by providing multiple fixing members that work together to guide the movable locking piece. This segmentation of the guidance function across multiple fixed points creates smoother sliding operation and enhances structural strength compared to a single fixing member.
Solution Approach 2:
The fixing members are designed with curved or rounded guiding surfaces that facilitate smooth sliding motion of the movable locking piece. The curved geometry reduces friction and wear, improving the ease of operation while maintaining a relatively simple overall structure.

AI summary
The invention provides a trunk such that a fixing member for a handle can be utilized effectively. The trunk includes: a trunk body (31); a lid (32) provided to be openable and closable relative to the trunk body (31); a handle (37) fixed to an outer portion of the trunk body (31) by a fixing member (38); and a locking mechanism (58) including a fixed locking piece (56) fixed to the lid (32), and a movable locking piece (55) which is movably provided on the trunk body (31) and which is engaged with and disengaged from the fixed locking piece (56) to thereby lock and unlock the lid (32). The fixing member (38) of the handle (37) is disposed inside the trunk body (31), and the fixing member (38) constitutes a guide body by which movement of the movable locking piece (55) is guided.
