Hidden-Adjustment Clamp Structure to Eliminate Exposed Thread Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable clamps used in transportation, such as for motorcycles and bicycles, pose a safety risk due to the exposed thread rod that can contact the vehicle or rider when the clamp opens, causing inconvenience and danger.
Innovation Solution
An adjustable clamp with a hidden adjustment structure that utilizes a first and second screw member and a support member, where the second screw member is slidably disposed in a through hole, allowing for linear movement without changing the exposed length, preventing the screw member from being exposed and interfering with the vehicle or rider.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the thread rod is rotatably disposed between the first and second arms to allow clamp ends to open and close, then the clamp can securely hold objects at adjustable positions, but the exposed outer portion of the thread rod increases with the open degree, causing contact with the vehicle or rider and creating safety hazards
Solution Approach 1:
The first screw member is received within the second screw member, creating a nested configuration where the adjustment mechanism is hidden inside the clamp body. The second screw member slides within a through hole of the support member, allowing adjustment while keeping the first screw member concealed, thus eliminating the safety hazard of exposed adjustment components.
Solution Approach 2:
The support member acts as an intermediary structure that houses the second screw member within its through hole. This intermediary mechanism allows the first screw member to be driven without direct exposure, mediating between the user's adjustment action and the internal threading mechanism, thereby hiding the potentially hazardous components.
2Ease of operation
If the thread rod is exposed to allow for adjustment of the clamp opening, then the clamp can be adjusted to different positions, but the exposed thread rod contacts the vehicle body or rider during turns, causing inconvenience and danger
Solution Approach 1:
The nested configuration of the first screw member within the second screw member allows the adjustment mechanism to remain concealed during operation. The user can still easily adjust the clamp by rotating the exposed second screw member, while the critical first screw member remains hidden, preventing interference with the vehicle or rider.
Solution Approach 2:
The potentially hazardous first screw member is extracted from the external environment and placed inside the clamp body through the nested structure. Only the necessary external interface (second screw member) remains exposed for user operation, separating the functional adjustment element from the hazardous internal component.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The clamp achieves a hidden adjustment function, allowing for secure clamping of objects without exposing the screw member, thus preventing interference with the motorcycle or rider, enhancing safety and usability.
Implementation Method 1
The first screwing part is screwed to the second screwing part. When the adjustment end is rotated, the first screw member generates a linear movement with respect to the second screw member
Implementation Method 2
The second screw member is slidably disposed in the through hole

AI summary
An adjustable clamp with hidden adjustment structure includes a first clamp body, a second clamp body, and an adjustment device. The adjustment device is disposed between the first and the second clamp bodies for adjusting the clamp opening size therebetween to clamp an object. The adjustment device includes a first screw member, a second screw member, and a support member. The support member is disposed on the first clamp body. The first screw member is disposed on the second clamp body. The second screw member is slidably disposed on the support member and screwedly combined with the first screw member. When the second screw member is rotated, the first screw member generates a linear movement with respect to the second screw member. The originally exposed length of the second screw member does not change, causing no inconvenience of usage, and achieving a hidden adjustment function.
